Eocene belemnites from Hungary The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible...

Underrated example of convergent evolution I feel. The hummingbird hawk-moth can feed on nectar using its proboscis while hovering in the air, just like a hummingbird.

Just placed an order on this one. Despite its price, not only would it be unique to my current collection, but I saw that it was low in stock, so I struck while the iron was hot.

I saw these photos on Instagram taken by brown hyena researcher Marie Lemerle. This is a brown hyena badly wounded by another. She was convinced he would die here, but he was actually seen again a few weeks later doing fine, albeit with big scars on his neck.

I and previous researchers would seem to think so, at least for those with the familiar fish-like body plan.

to injure prey wouldn’t hurt.

of is that headbutting wouldn’t be contingent upon fitting a piece of the prey item in its mouth to rip off, only that the predator hits hard (and it would certainly be more applicable than any of the clawed limbs). Ofc that’s why theropods had huge jaws to begin with, I just thought a 2nd option—

Tbc I can’t actually say that it was done *at all*, just a theoretical second option. I agree cutting out a large wound with jaws would be more efficient at actually killing a large prey item (orcas have to ram large baleen whales numerous times to debilitate them), but one advantage I can think—

Tyrannotitan and Patagotitan. The latter I sort of doubt is meant to be depicted at full size. I see it more as orca-like headbutting to progressively wound than to actually push over.

Something I realized I also liked The Dinosaurs was the way it portrayed pterosaurs over time. At no point are the pterosaurs claimed to be on the decline. Here, whenever they pop up, they remain successful, if anything being “bigger than ever before”.

Literally an idea I had in my head for a while that turned into an actual sculpt. If this isn't the most badass dinosaur sculpt I have ever seen...

to dismember, and so a bite from an alioramin would still have been pretty vicious. Not to mention powerful legs to kick with.

I think some recent papers proposed that alioramins might themselves have been prey to larger tyrannosaurids. While that’s probably true, and their skulls were better built for small prey, they were still long and filled with serrated teeth. They still had to have some capacity—

I just know that if Hesperornis were alive today, we'd get the occasional case report published about someone getting bitten or pecked, how much they bled/got infected, all antibiotics used over a numerical period, and of course, a picture(s) of the wound.

Apart from a large figure that I ordered last week, I'm debating what the smaller figure(s) I should get next. Options are between retired CollectA figures, new Schleich, current CollectA, and Haolonggood. What do y'all think?

Its ventral surface isn't light in color by contrast, or at least not nearly to the extent seen in an orca or a white shark, which is what I'd like to know if any previous researchers provided an explanation for.

I finally watched the last episode of The Dinosaurs and the newest episode of Primal tonight. A couple things.

1) Yay, they emphasize birds as dinosaurs THOROUGHLY.

2) Finally saw something I've been waiting for since Primal S3's teaser.
