[Geology2] Unexpected exoskeleton remnants found in Paleozoic fossils

I love when that happens . . .

Unexpected exoskeleton remnants found in Paleozoic fossils
PhysOrg.com [USA], February 7, 2011

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 fossils of
arthropods from the Paleozoic era. Previously the oldest molecular
signature of chitin-protein complex was discovered in 25 million year
old Cenozoic fossils and remnants of structural protein have also been
discovered in 80 million-year-old Mesozoic fossils.
