It's time for Fossil Friday! Meet Cryptocleidus oxoniensis, a short-necked plesiosaur. Plesiosaurs were large marine reptiles that lived from the late Triassic to the end of the Cretaceous. The plesiosaurs had extensive modifications to the shoulder and pelvic girdles: these elements form large, flat sheets of bone, presumably for the attachment of swimming muscles. Cryptocleidus' trunk was very rigid and short, and the short tail could only function as a rudder, leaving the limbs as its main organ of propulsion.

Here’s a weird throwback for ya- it’s not a squid, it’s an ammonite. Ammonites were around right up until when the big dinosaurs went extinct.
Nipponites look like freaky meatballs, but scientists (using a *lot* of math) realized it’s a predictable meatball. When you first look at it, you might think "Um what the shit?" but apparently there is some kind of order in there. Just don't ask me to explain it to ya.

This is true of most Egyptian relief work with animals. If you don't believe me, have a look at Hatshepsut's Punt reliefs and the fish.

Thought of this meme with Hallucigenia, an ancient cambrian-era animal. Now that I think about it, it should probably have more spikes :P

It’s Trilobite Tuesday! Meet Heliopeltis, one of Morocco’s strangest Devonian trilobites. This 400-million-year-old marine arthropod had a small body, large eyes, and long spines. Scientists think its unusual physique indicates that this species floated on gentle ocean currents.

Pre-Historic Waters: The Tully Monster
Tumblr media
These strange but wonderful creatures were up to a foot long and lived about 300 million years ago in the at the time shallow tropical waters of Illinois.
Tumblr media
These strange, soft bodied creatures were discovered in the mid-60s by paleontologist Eugene Richardson and are believed by some scientists to be similar to modern-day lampreys.

(Let me know if you folks are interested in pre historic water life too! I'd love to talk about them more.)

port Jackson sharks?
DYK…
Tumblr media
port jackson sharks are considered to be harmless, however, if provoked they could pose a threat.
port jackson sharks are a nocturnal, bottom dwelling 'bullhead' shark endemic to the Great Southern Reef. these sharks grow up to 1.65m and can live for more than 30 years. they usually live at depths of less than 100 metres but have been known to go as deep as 275 metres.
port jackson sharks are not an endangered species and is not used as a common food supply. it is, however, useful when scientists are hoping to study bottom-dwelling sharks and can be vulnerable to being caught as bycatch.
