I've got a question about the last common ancestor of sauropsids and synapsids that I wanted to bring up. The last common ancestor of all extant amniotes existed something like 310 million years ago. By implication, does this mean it must've produced at least two offspring who are common ancestors of sauropsida and synapsida respectively (but not the other group). Or does the concept of 'last common ancestor' not function this way? submitted by /u/TDM_Jesus [visit reddit] [comments ..read more

As a kid, I got picked on for loving dinosaurs, and one of the worst things people told were that dinosaurs weren't real. I don't care if people said they sucked or they didn't like them, but when someone says something like that, it flat out pisses me of. I get really anxious with the fact that the creatures I loved all my life are called fake. Even now, white b***ces like Allie Beth Stuckey and that one girl from tiktok saying that pisses me of so much and makes my anxiety work. How do I let myself know that dinosaurs are REAL and ignore what the haters have to say (and can we all roast the ..read more

I know the other Torosaurus species (aka latus) is dated 68-66mya. Just wondering what age is given to T.utahensis. Is it older than T.latus or the same age? submitted by /u/Budget_Childhood_351 [visit reddit] [comments ..read more

Personally I’m leaning towards Permian. You’ve got so many huge clades that just vanish, while the Cretaceous was generally more a smattering across the board. The effect on mammalian evolution was certainly more pronounced due to the great dying. Curious to know what y’all think and if there’s any good papers on this I can look at submitted by /u/thunder-bug- [visit reddit] [comments ..read more

So, my 4.y.o. is making his daddy proud by being a big dino fan - and unsurprisingly, T-Rex is his absolute favorite. Unfortunately, there aren't many T-Rexes around in Europe, so we haven't had a chance to check one out yet. Closest that I was aware of is in Berlin, and that's a 9h drive. Now I've stumbled across this museum in Bavaria (private/commercial) that claims to have the skeleton of a juvenile T-Rex (nickname Rocky). It's much closer by and at 10m in length even a not fully grown Rex is probably mighty impressive. The museum is, however, a bit pricey, especially seeing how they don ..read more

So hypothetically speaking, say aliens from the future discovered a fossilized skeleton of a human that had dwarfism. Assume for the sake of argument, these aliens only had technology on the same level that we currently do. And also, that these aliens have never seen a human in real life. They don’t have access to anything created by people (videos, art, architecture, etc.). The only thing they know about people is the fossil. In absence of other human fossils, would the aliens just assume that all humans were little people? If an average sized human fossil was discovered, would the aliens be ..read more
