The Unlikely Arms of a Fossilized Predator The discovery of Carcinonepa libererrantes, an ancient insect with crab like claws, has left scientists in awe of its unusual anatomy.
This fossil, unearthed from amber in Myanmar, reveals an independent development of chelae, claw like structures that are typically associated with crabs and other decapods.
Researchers used micro computed tomography and morphological comparisons to demonstrate the distinctiveness of these claws compared to those found in other insects.
