accordingtocryptozoologist:

According to Cryptozoologists Loren Coleman and Patrick Huyghe, Lakes Bear, Utah and Powell (all in Utah) and some other places in North America are haunted by giant beavers. Only one sighting from man-made Lake Powell is explicitly of a giant beaver, the rest are vague, remarkably un-beaver-like (“alligator-like jaws”, “reptilian”, etc.), or legends. Even among cryptozoologists, this doesn’t seem to be a very popular cryptid.

There were real giant beavers (Castoroides), which weren’t towering sloth-like beasts.

I read lots of bizarre hypotheses by cryptozoologists, so much so, I’ve started another blog. The (Internet) world needs to know about the Giant Beaver Hypothesis.

Fan-art of a recently (semi-) published hypothesis: that the bizarre internal structures on beaked whale skulls may be used for ‘visual’ sexual display, despite being surrounded by soft tissue. Apparently this bone — some of which is the most dense known — could still be detectable to an echo-locating beaked whale. The title of Gol’din’s article rather memorably calls them ‘antlers inside’ and… I sorta ran with it.

Cephalopod* phylogeny according to Fuchs et al. (2013). Contrary to conventional wisdom, belemnoids were not found to be extinct, rather, there appears to be a transitional taxa (Longibelus) between them and decabrachians (squids, cuttlefish, Spirula). True squid are thus a surprisingly young group and amazingly, lack a fossil record; fossils previously regarded as squid are now thought to be vampyropods (vampire squid and octopuses).

* More specifically, covering crown-coleoids and one stem-coleoid, not all cephalopods.

Stepanov N.P and the Penza Specimen in 1929. This huge, partial skull was recently assigned to Mosasaurus hoffmani; measuring over 1.7 meters in length, it is from one of the largest known mosasaur specimens. The arrows are pointing to an incorrectly placed left angular.

At the Audubon Society of Rhode Island’s Environmental Education Center, the resident blue lobster molted and came out purple. I’ve seen lots of blue lobsters molt before, but this is a first.

There aren’t very many photos of Jesus, and fewer still of Him fighting dinosaurs.

This photo just turned up in the university archives. It seems to show a man battling a stegosaurus! Roy Mackal was right!!

Beautiful. Especially the desperate sloth watching the guy on the toilet.

Diver with a live ateleopodid identified as Ijimaia sp. from tamar.org.br. Jellynoses can be rather big fish — up to 2 meters long — but I’m sensing some forced perspective in this photo.

Recently an I. antillarum made the news when it was captured off Florida, and judging by the comments I’ve seen, this group of fish is almost unknown to the public.

Captive Claudius angustatus from Aquarium Zone. This species has no bony connection between the plastron and carapace (lower and upper shell), which allows the turtle to make threat displays by partially retracting its head with its huge mouth open. This isn’t a threat display… I’m not sure what is happening here.Incidentally, Tetrapod Zoology just published an excellent article on Mud and Musk Turtles.
