CADDY NASH 2

The Plesioturtle by Thomas Finley 

      When the first images from the Kelly Nash "Cadbourosaurus" video were released to the public a few years back there was a keen interest by aquatic cryptid fans and researchers in the clips and story that went with the video.

NASH series I -  Triangular head breaks the surface

   Being that there is very little usable or un-hoarded video footage out there of any aquatic cryptids, the Nash footage attracted much attention. Researcher John Kirk was given a private showing of the entire event and seemed excited by the prospect of footage that he felt showed a group of unknown creatures being chased by a pack of killer whales.
   The first snippets of footage released publicly consisted of about 7 seconds of lower resolution footage of what appeared to be several low lying, surface swimming animals moving along as a group. In this first series of clips, no whales are visible.

   The limited footage did not resemble the proclaimed profile of the animals as described by many witnesses - that being a camel faced, loop producing serpent whose reported slender, snake like body would coil out of the water to the point of sometimes actually showing daylight thru the hoops.
     In both series of the now public Nash clips there are no long-necks or coils or "horsey" looking heads that visibly break the surface shown at any time.

   Most researchers disagree on what the animals possibly are, with nominations made of various ancient reptiles - now thought to be extinct, mis- identified elephant seals, long necked pinnipeds not in the fossil record and the thought to be extinct "Super Otter."
   Ogopogo has often been described to posses a "Horse-like head" too.
   Whatever Ogopogo is, it lives inland from Caddy, in the 100 mile long Lake Okanagan, which  was connected to the 
                                                         British Columbian sea 8,000 years ago.

   Before his untimely passing, Kelly Nash made it clear that these animals were not anything he's ever seen before, so whales and other commonly seen sea-life might be ruled out by the on the job knowledge of someone with an over 40 year fishing career in that area of British Columbia.

    As in the original clips, the animals can be seen to cluster with one another. Kelly's son, Kyle Nash remarked that you can see "a bunch of them swimming very close together," so he realized that this was not some giant singular hump connected beast. Instead there seems to be several of these wake producing animals cruising along at a good speed, and apparent square-ish shaped heads and eyes are visible in the cluster, most prominent on the lead animal.

CADDY cluster of humps and heads ?

   The animals are swimming from right to left at a decent clip and at one point son Kyle Nash is impressed by the speed of the group and is heard exclaiming "look at how fast they're swimming." Unfortunately, most of the frames from this new footage suffer from motion blur, but several in-focus images exist if examined frame by frame. 
What may be a series of undulating humps are seen- sometimes swimming in a row, and sometimes swimming side by side while clustering together to create at times a single almost unidentifiable writhing mass.


3 in a row - eye visible on center animal ?

     One of the ideas by various researchers over the years is that some of these more humped aquatic cryptid sightings are unknown giant single animals somehow equipped with fatty flexible lumps on their backs that roll up on their spines and give the appearance of the multi- humped monsters mentioned occasionally by witnesses. Another assumption is that the animals are snake like in nature and coil to create the humped presentation. 

A youngster ?

    Viewing the Nash footage, one can see these particular animals swim in a tightly formed group. It may be easier to see where all the different shaped humps in reports of aquatic cryptids might be coming from. In both series of the Nash clips it's hard to tell where one animal ends and the next begins. They are not always swimming in a predictable circus elephant row either, but swimming besides and over each other and keeping close to the lead animal in the pack as well. If an observer were not to take this suspected behavior into account then it would be easy to think that these protrusions were all from the same hump- connected uber- animal. In the 2nd batch of footage there are no whales visible again, which may suggest that there is even more unreleased footage yet to come.

   An idea postulated by Prof. Roy Mackal while researching on Loch Ness 40 years ago was that some humps could also be the result of youngsters hitching a ride on the back of an adult animal. Such behavior would explain how it's possible that eyewitnesses have reported seeing a row of humps where one of the humps in the middle would suddenly disappear. As to the possible identity of what we are seeing in the Nash footage, fully aquatic turtles should be considered as a prospect.

   Cold water tolerant Leatherback turtle pods are sometimes seen to swim in a similar fashion to what is observed on the Nash footage. Turtles don't always need to have rigid, cumbersome shells. The Leatherback turtle has a very flexible carapace, as do the worldwide Trionychids or softshell turtles.

  If Caddy is a turtle, then why no reports of shells being noticed ?
Turtle's shells can sometimes take on the color and pattern of the skin of the animal thus giving the illusion that there is no shell at all, an idea that may have been suggested by one  aquatic cryptid researcher who once described Lake Champlain's "Champ," after witnessing it close up, as
" a Snapping Turtle without a shell." Such a  creature as a "shell-less turtle" has not existed zoologically since the order of the Placodonts, some quarter of a BILLION years ago. (250 million). Could it just be that the shell was not noticed ?

   On many occasions, Caddy has been described as "turtle-like." Could it be that there is in fact a shell, but that they are one of the species where the shell is not detected easily ?

  Hopefully there is more footage to be seen. The additional 8 seconds from the 2nd camera is important in that it could help identify the animals as not being waves or seals/ pinnepeds, whales or plesiosaurs, but perhaps something else.  The shape of the head in the Nash series seems not to be horse shaped, but looks to be a "turtle- like" creature of some kind looking into the camera with several swimming companions snuggled up against it. Could it also be that additional reports of coiling or long, overly thin necks are miss-identifications of the creature's long fins breaking the surface ?

  There is usually an expectation by researchers to hear about the long neck, believing these creatures to perhaps be Plesiosaurs, yet many sightings on places like Ness, Champlain and Okanagan report a short necked animal.
   What kind of animal can have both a short or long neck ? Only a turtle.

   Another pro-turtle idea came from "Cadborosaurus, Survivor from ther Deep" author Ed Bousfield who speculated that the animals were reptilian in nature and were able to breathe underwater, an ability that can only be attributed knowingly to the order of Testudines, via the use of cloacal gills.

Is that a head and reptilian brow-ridge up front ?

   Joe Nickel and Ben Radford have pointed out in their book "Lake Monster Mysteries" the wide variety of conflicting lake monster reports from Lake Champlain alone. The endless variations of manes, back structures, humps and head neck configurations, although believed seen and reported, may not be what they really look like. They are not always described in a consistent manner.
   Could it be that the pandemonium of the animals swimming around and over each other at an Olympic speed be responsible for the humps and bumps ? Considering the apparent behavior on the video taped by the Nash videographers, it may be worth considering.

STUPENDEMYS, the world's largest TURTLE

 PLESIOTURTLE by Thomas Finley

   Imagine yourself a passenger on a time machine that suddenly deposits you in a foliage covered jungle swamp on the edge of a lake. A quick glance around and you are taken aback by the sheer number and variety of crocodilian residents floating about the reeds edge, eyes above water, lurking silently. Suddenly, an explosion of foam and water by the shoreline and a 40 foot monster called Purussaurus leaps onto land and takes down a 1000 pound herbivore. Elsewhere out on the lake, huge domed objects, the size of a mini-van, break the water's surface and cruise along, looking much like the famous Nessy hump shaped back you've heard about so many times. Up on shore, 15 foot tall creatures, standing bipedally are stripping the leaves off the trees.

If this sounds like a typical Jurassic day, you may be surprised to know that the scene described took place just 8 million years ago in Urumaco, South America, some 55 million years after the demise of the Dinosaurs.  

   Every so often, Paleontologists will hit the jackpot and make totally unexpected, monumental discoveries. Such was the case in the summer of 1972, when a Harvard paleontological expedition working in post Tertiary deposits of northern Venezuela dug up the remains of several huge fossil turtles. One of these turtles was bigger than any still living Chelonian and eventually proved to be the largest turtle ever recovered, even bigger than the previous champion giant, the Cenozoic oceanic Archelon.



ARCHELON

Turtles probably constitute the most readily recognizable group of all vertebrates, with their trademark shell consisting of two parts, a dorsal carapace and a ventral plastron. Both sides are connected through a boney bridge, which completes the encasing of organs and even the shoulder girdle, a unique feature among living vertebrates. It's a feature one must go back to the Triassic Placodonts, almost a quarter billion (235,000,000) years ago to see it in any other animals.

PLACOCHELYS

As early as the 1930's, American oil companies like Texas Petroleum were scouting out Venezuela looking for new oil fields to tap, and in the process unearthed some interesting Miocene through Pliocene fossils. By the 1950's, Paleontologists from South America took up the fossil search in their own backyard. In 1972, Bryan Patterson from the Museum of Comparative Zoology at Harvard led an American expedition to Urumaco, and their discoveries led to the first series of publications on specific aspects of the Urumaco fauna, including many new turtles and crocodilians, one of which would turn out to be the world's largest turtle.

   Of the several new turtle species, team expert Roger Wood determined that the biggest one recovered existed fairly recently, swimming in the Venezuelan lakes, rivers and swamps perhaps up to just a few million years ago. This giant, aptly named Stupendemys Geographicus was a Miocene/Pliocene, fresh water aquatic turtle of gigantic size. The shell alone was estimated to be nearly eleven feet long !

 The team uncovered an almost complete carapace, along with partial fragments. The shell was unearthed in an upside down position and detailed examination of the scute arrangement (shell pattern) led Wood to the conclusion that this was of the super-family Pelomedusidae, a type of Pleurodira. Pleurodiras are the sub-order of the order of turtles we know best here in North America, the Cryptodiras. Pleurodiras are also known as "side-necked turtles," because they retract their necks into their shells by folding it over onto itself, unlike the direct retraction method used by the Cryptodiras. Pleurodiras at one time were the dominant order, having worldwide distribution, but today are only found south of the equator.  They are the sub-order responsible for the snake neck turtles (Chelidae), which include what is commonly referred to as one of the world's weirdest animals, the Mata Mata Turtle. 

Different neck retraction of the 2 orders.

   This uniqueness of Pleurodiras can be attributed to the long term isolation of Australia and surrounding islands from the rest of the world, as well as South America and Africa, to a lesser degree. Thus the most recent evolutions of the Pleurodiras took a different route than their northern counterpart Cryptodira since being isolated by continental drift, some 30 to 60 million years ago.

   Despite physical similarities with it's extant relative, Podocnemis, the size of Supendemys was beyond immense, perhaps more than 100 times larger than the largest currently known South American Pleurodira. Along with the shell, some fragments of the plastron were recovered along with a massive, hulk-buster humerus bone that Wood speculated was most likely hinged into a huge modified leg/paddle, a feature found on the modern day Carretochelys, a small Indonesian fresh water turtle quickly approaching extinction at the hand of man.

   Wood described the shell of Stupendemys as "gigantic with a depressed carapace pocked with irregular nodular contours on external surfaces and a deep median notch at the front. The anterior border of the nuchal bone is thickened and upturned in a curved collar configuration that is unique among Chelonians. The carapace is low arched and flattish, in the manner typical of aquatic turtles."

   Stupendemys had features that resembled modern Pelomedusids but also had different features as well. Enough in fact for Wood to describe it as "aberrant." Other unusual anatomic differences from modern peliomedusids include the placement of the glenoid (arm) socket, which faces forward rather than laterally like the modern podocnemis exspansa. This hints at the strong possibility that the animal did have fins or paddles, swimming via a modified breast-stroke. 

Possible powerful huge finned Stupendemys

   Despite Wood making the supposition that the massive humerus could be realized in the form of a huge paddle or arm/fin combination, subsequent museum representations of Stupendemys do not usually follow his original vision of the animal and complete models sometimes portray a lumbering giant Terrapin with curiously atrophied limbs.

AMNH's  rather weak representation of Stupendemys

   And in further contrast to some of the cumbersome recreations, the original estimates of a heavily laden animal were later dispelled when Marcelo R. Sanchez-Villagra showed that the composition of the shell was not a solid bony type but a criss-crossed matix of fibrous tissues resulting in a lighter weight carapace, such as fiberboard in construction, retaining strength but losing much weight in the process. That weight saving could serve to add extra speed to it's swimming abilities as would the large paddle- fin.
   Huge fins on a large turtle give it carte blanche for international travel, something borne out by the sub-artic hopping leatherback turtles (dermochelys). The only other vertebrate that has a wider natural distribution are some species of whales.

   Given what Wood has written about the humerus, one should think that these creatures were powerful swimmers, confirming what we already know about big humerus bones in turtles. The oversized humerus of the Galapagos Tortoise for example, bears the weight of the animal (up to 300 pounds) and extra weight is not a problem. 

Zoologist Gazillionaire Walter Rothschild

   In the leatherback turtle the big humerus is manifested in a large front paddle of maximum surface area resulting in great speed when needed. Leatherback turtles can swim as fast as the world's fastest Olympic sprinters. Wood 's final summation was that "Stupendemys was a highly aquatic type of turtle, most probably a fresh water preferring example but possibly being able to live in salt water too. One or more pair of limbs were most likely modified into flippers and the head and neck may have retracted in a different manner than current side neck turtles." 

   Stupendemys existed at a time when proto-humans walked the earth, making them much more acceptable as a potentially surviving species, taking into account the order of Testudians' ability to have survived the Tertiary event that wiped out the dinosaurs, it should make them a top modern day candidate for large unidentified aquatic reptiles as described from Loch Ness, Lake Champlain and other large lakes. Add to that, turtle's present proven survivability, adaptability, diversity, potential extreme size and extreme range of distribution in the world.

Snake Necked Pleurodira

   There are gaps in the fossil record in the progression of Pleurodira, especially the snake necked turtles. If Stupendemys represents it's family with extreme gigantism, then what could represent and maybe still represents the possibly equally giant predecessors to the current day snake-necked turtles ?

 Plesioturtle as The Loch Ness Animal

   If there was a snake necked turtle with flippers that was also 100 times bigger than today's versions, then you may have a creature that looks much like a Plesiosaurus would be expected to look like. Considering the difficulty in obtaining even one fossil example of the Stupendemys, it is conceivable that there may be a recent Snake Necked Turtle equivalent waiting to be unearthed or even a currently living example waiting to be positively identified.

   On many occasions, lake monster and sea serpent witnesses have mentioned that the creature had "turtle-like" features. And in other instances the sighting has been accompanied by a foul odor, another trademark of the snake neck turtle, which is nick-named "stinkpot" in it's native Australia. Both of these features were observed with the infamous Pensacola "sea-serpent" attack, among others.

monster and drew this picture

   As confirmed by our current zoological knowledge about the living 300 species of Chelonians, anything that looks turtle-like should be a turtle. Also given the creature's abilities to withstand cold water, hibernate for months at a time, be omnivorous, swim deep and fast, have worldwide distribution, amazing breath holding ability, an internal gill system that produces oxygen while submerged, have camouflage abilities and the newly discovered ability to produce underwater high frequency complex communications - unclassified gigantic turtles should be considered a top candidate for the identity of many lake monsters and unknown sea creatures claimed around the world.
