Which Came First? Eggs Before Chickens, Scientists Now Say

A rare fossilized dinosaur nest helps answer the conundrum of which came first, the chicken or the egg, two paleontologists say.

The small carnivorous dinosaur sat over her nest of eggs some 77 million years ago, along a sandy river beach. When water levels rose, Mom seems to have fled, leaving the unhatched offspring.

[...] Well, it’s still unclear whether chicken eggs or chickens came first (the intended question in the original riddle), said Darla Zelenitsky, a paleontologist of the University of Calgary in Alberta who was the first scientist to closely analyze the dinosaur nest.

But interpreted literally, the answer to the riddle is clear. Dinosaurs were forming bird-like nests and laying bird-like eggs long before birds (including chickens) evolved from dinosaurs.

"The egg came before the chicken," Zelenitsky said. "Chickens evolved well after the meat-eating dinosaurs that laid these eggs."

Okay, so now which came first? The dinosaur or the egg?
