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.
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.
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.

Omg lol. Dinosaur scientists have been extinct for like hundreds of years.

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

Are you sure? I opened up YouTube yesterday and saw a dinasour right there.

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.

Or what they taste like if you serve them with a side salad

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

Every dinosaur I've ever eaten has tasted fowl.

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

They've actually started figuring out some colours believe it or not. I'll see if I can dig it up... Edit:
https://en.wikipedia.org/wiki/Dinosaur_coloration
There's a decent video on that page too.

Oh I never really thought about the fossil record being sedimentary, this largely aquatic and adjacent environments.
Swedneck@discuss.tchncs.de · 3 pts · 143d
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.

Brachiosaurus wasn’t a mammal.

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