"The incredible diversity of pterosaurs is perhaps best expressed in one of the prehistoric flying reptile's most intriguing and mysterious features: the head crest."
What evidence from the text supports the idea that the diversity of pterosaurs is best
expressed in their head crests?
A "Many pterosaurs had flesh-and-bone crests atop their skulls - dramatic
anatomical characteristics whose purpose is still debated by paleontologists."
B "Akin to a rooster's comb, peacock's crown, or the frill on some lizards!
necks, pterosaur crests were prominent anatomical features found across many
species."
C "Pterosaurs crests are thought to have been fairly ubiquitous, appearing in
many groups of pterosaurs from the Triassic (252-201 million years ago)
through the Jurassic (201–145 million years ago) and Cretaceous (145-66
million years ago) periods."
D "Among pterosaur species known to have had crests, there is an amazing
range of shapes and sizes."
