Researchers discovered a 520-million-year-old fossil of an arthropod named Youti yuanshi that still had its brain and guts ...

Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex -- structural materials containing protein and polysaccharide -- are present in abundance in ...

A 505-million-year-old fossil provides hard proof of what scientists had previously only suspected: Ancient arthropods shed their exoskeletons during growth, just as their modern relatives do.

Molting, that periodic ritual in which arthropods shed and replace their outer skeletons, can be a dangerous time for the creatures. Just ask the trilobite. Research published by a Michigan State ...
