For #FossilFriday, check out the images of this amazing #Pleistocene griffon #vulture, entombed in an Italian pyroclastic deposit, and preserved as a space in the block. Iurino et al. (2014) scanned the block and were able to reconstruct the animal in 3D!! #vultures#birds More.. pic.twitter.com/7HWjdh2iE1
