Well I was born in the 90's and they weren't around then so it tracks.

If it's strong enough to throw an F-150, that dino is fucked. Also, we barely know what lived in upland and interior environments, so who knows what adaptations they had. Most dinosaur fossils come from lowland settings near rivers and coasts where rapid burial was likely. There are whole ecosystems we've basically never sampled.

This drives me crazy. Along with the fact that we'll probably never know about the various colors and fleshy structures that these animals had.

We know for a fact that at least one dinosaur tastes like chicken.

Chicken! Maybe turkey, but probably chicken or possibly another game bird, but probably chicken!

Yeah I was gonna say, one of the defining features of the large sauropods was a low body density due to the air sacks in their huge necks and hollow bones. Those adaptations were likely required to achieve their size. So you have a really big animal with relatively low density and high surface area, that thing is going right up into the sky and getting smashed to bits when it lands.

Oh I never really thought about the fossil record being sedimentary, this largely aquatic and adjacent environments.

clearly this means there were sauropods with wings, who evolved to use tornadoes for transportation

You just do a quick laydown and tuck your head under your arms, and find a bit of dirt to hide behind.

Nearly all tetrapods have a laryngeal nerve that goes from the brain stem to the larynx, but doesn't go straight for the few inches, instead travelling down the neck to go around the aortic arch above the heart. It's a throwback to when we were ocean dwelling and had gills much closer to the heart.

In giraffes this nerve takes a 15 ft detour.

In something like a brachiosaurus which had a neck around 30 ft long, this would be a 60ft detour.

A great proof of evolution, of making do with what is there and adapting.

I wasn’t gonna say this but since you’re making changes anyway: the recurrent laryngeal nerve doesn’t go around the heart but around the aortic arch and the great arteries.

....yes. but I also straight up didn't notice this was a screenshot from reddit until I read your comment.

I certainly care about sources, but far less when it comes to shitposting.

I'm a late Lemmy joining only after the blackout cos fuck reddit and fuck spez.

And you know what Lemmy is better.

Well, back then there was more oxygen in the air, which allowed tornados to grow larger.

bull is a generic term, there were absolutely bull dinosaurs. Like there was at least one species of herbivorous dinosaur that lived in herds and had strong sexual dimorphism.

Hadrosaurus in a Hurricane? T-rex in a Typhoon? Centrosaurus in a cyclone?
