Tiny polar dinosaur footprints found

Adam Khor

In Australia, and they seem to have been left by ornithomimosaurs or something very similar. The footprints suggest chicken to crane-sized animals, and they were left during the Early Cretaceous.

Awww, like an itty bitty lil' dino family

Dino chicken.

Frozen Dino Chicken.

Had sage and onion been invented by then?:D

This is the sort of news that really got my interest. I am fascinated by creatures living in the polar regions. It shows just how diverse life was back then, and it isn't just a 'modern' phenomenon.

(I wonder if we will ever see evidence of a dino penguin?)

All penguins are dinosaurs [/pedantic]

Sure, there was that 5 foot tall penguin from prehistoric times:

But if you want one from the mesozoic the closest you're likely to find is this ugly mug:

Which Primeval made even "uglier" by stripping it featherless...

I assume one of the Plesiosaurs would be the equivalent of a Leapard seal in that case.

Does anyone know if any of the marine reptiles frequented polar regions?

Yes they did; three-crested Umoonasaurus and needle-toothed Opallionectes from the early Cretaceous both lived in polar waters in what is today Australia. They were discovered before it was confirmed that plesiosaurs were warm blooded, so there was already much talk about that possibility since then.
Kronosaurus is another example, hence my drawing of a hungry Krono coming out of a breathing hole in the ice to grab some dinner

Ichthyosaur Platypterygius also lived in polar waters.

Rubecula

That drawing is awsome. It is a Kronosaur?

Don't suppose you could do a comparison sketch on what a Kronosaur and a Liopleuridon looked like could you? They do seem to be remarkably similar (what we think they looked like anyway.) And you know my fascination of all things marine reptile orientated.

Yeah its a Kronosaurus.

And yes, I guess I could, although it seems that none of them is known by complete remains. Some of the remains previously assigned to Liopleurodon ended up being a completely new creature, so...

Ah yes thats true. Well nevermind then. I do sometimes get carried away. Sorry:o
