The constant insistance that the dinosaurs never "truly" died out because they became birds I think has caused some gullible folks to literally believe birds are dinosaurs all along. They're not modern-day fossils like the "living fossils" which are called as such because they evolved so little or not at all since when they first showed up in the fossil record and some species still exhibit primitive features like being lobe-finned or being a jawless fish like the lamprey and hagfish. Then there's the monotremes (platypus and the echidna) exhibiting the primitive method of laying eggs as mammals although the species themselves did evolve at some point.idk about anyone else, but I've gotten REALLY annoyed at the constant insistence with people calling birds dinosaurs. Like not even simply that they evolved from them, just straight up calling them dinosaurs, to the point where some lunatics want to categorize birds as fucking reptiles now.
Do we call amphibans "fish" or mammal "reptiles" because one came from the other? Fuck no. Let birds be their own separate thing dammit.
A few birds are considered living fossils, such as the pelican and the hoatzin whose chicks are born with two-clawed wings to climb trees, but that still doesn't make them dinosaurs. Oh, and much like the horseshoe crab and the coelacanth, mantis shrimps occupied the same waters as other prehistoric marine reptiles, first branching off in the middle of the Carboniferous and remained relatively unchanged since. They're fucking badasses, I bet there was actual claw-to-claw combat between them and the eurypterids.
But uh, yeah, "living fossils" =/= dinosaurs.
