wait are chickens actually decended from t-rexes or is it just a comedic pairing
Chickens and T. rex share a recent common ancestor, more recent than T. rex shares with Stegosaurus or Brontosaurus/Apatosaurus
Chickens did not descend from T. rex, because T. rex is a very specialized and derived dinosaur
However, they - and all other birds, because all birds are in a single group - descended from small raptorial dinosaurs like Velociraptor. And, the common ancestor of Velociraptor and all birds (including chickens) could fly
And since birds descend from the same common ancestor as all other dinosaurs, they're dinosaurs.
Its that time of night again when my body gets really cold to tell me to go to bed and instead i put on a hoodie and continue to research magma
It's weird how geological time works. Eras start and end bit by bit over the course of hundreds of thousands of years. That sounds like a big uncertainty but that sort of timescale, on which the climate can overhaul itself completely and entire species rise and fall, is instantaneous compared to the age of the earth. Any hypothetical sentient creature would have no idea it was living through a major turning point. The Silurian slid into the Devonian as land plants became A Thing and insects started to wonder if 'pilot' might be a good career path, but there was no one moment when one thing ended and another began. That's not how that works...
... except for the Cretaceous. The Cretaceous had a Last Day and it was probably in April, and then the next day it was the Paleogene.
It saddens me deeply to know I cannot collect every rock
I cannot collect the smallest rocks because I would lose them
I cannot collect the biggest rocks because arm's weak
I cannot collect the funkiest rocks because no money
I cannot collect the spicy rocks because they hurt
I cannot collect the space rocks because gravity
What horribleness, how dare existance not allow me the rocks
Oh well, at least the'res plenty of rock that I Can collect

Okay then, if you're so very clever...
If we're not meant to eat rocks, how come they're named shit like "apatite"?
You're damn fucking right I have an apetite.
