Fact 136: What came first, the chicken or the egg?

Fact 136: What came first, the chicken or the egg?

Now, apparently this is one of those unanswered questions, a mystery to everyone, and yet everyone delights in the knowledge that chickens descended from dinosaurs and in the knowledge that chickens are currently the closest living relative of the T.rex.

Dinosaurs are famous for being reptiles (sauropsids) and having eggs that look massive!

Dinosaurs predate chickens and birds.

Spoiler alert the egg came first!

The oldest dinosaur fossil is roughly 230 million years old (according to the Natural Geographic), and the oldest bird fossil is about 150 million years old (according to the Natural History museums)

So 230 million -150 million = 80 million, so, give or take, the dinosaurs predate the chicken by 80 million years and there for, so does the egg.

It is likely that the chicken descended from a group of dinosaurs called theropods (theropods includes the T.rex) in a group called Coelurosauria. "This includes not only tyrannosaurs and birds, but also the ornithomimosaurs, therizinosaurs and compsognathids."-Natural History Museum.

The egg came first!!!
