Vinctifer

Santana fish

Vinctifer comptoni is the long, armoured, needle-nosed fish preserved three-dimensionally in Romualdo Formation concretions from the Araripe Basin, Brazil. Nodules with Vinctifer were exported in huge numbers before enforcement tightened; today they carry the same legal cloud as all Brazilian fossils. Their preservation, with scales and bone in the round, is unmatched.
