First known amphibious dinosaur discovered

[DavidBrown]

Meet Halszkaraptor escuilliei, the first recorded amphibious dinosaur. It had teeth adapted for grabbing fish and front limbs that look like penguin flippers.

So Spinosaurus, Lurdusaurus and various arms of the avian tree (such as penguins, auks, grebes, loons, ducks etc) don't count as aquatic/amphibious dinosaurs???

Aquatic and amphibious are different things. A fish is aquatic but not amphibious.

Aquatic and amphibious are different things. A fish is aquatic but not amphibious.

Given that 'aquatic' relates to living in water for most or all of its life, it could be said that some bird spp virtually never leave the water.

How to Tell If a Dinosaur Is Fake

An interesting article. It features the author of the paper about Halzkaraptor saying that basically he is confident to have proven it isn't a fake to the best of current capabilities.
Basically everyone seems to think this is the real deal, but they are very conscious that if it wasn't it would probably look like this.

Yes, but the artical said the dinosaur was the first amphibious. Even if these birds are aquatic, they aren't amphibious!

Mudskippers or the climbing perch, among others, might beg to differ. ^^

At this stage, we're pretty much subjecting the genus Lepus to excessive taxonomic re-assessment

Reminds me of Hastead's dodgy interpretation of C. corallestris.

The forelimbs resemble flippers somewhat yet are too small to be propulsive, the hindlimbs do not look like thse of an aquatic animal and the tail obviously isn't a propulsive organ. Maybe the wings were used in steering underwater, but if so, how could H. have propelled itself? Seems to me that apart from those flattened forelimbs H. could as easily be a ground or waterside bird, as it is a divng animal.
