Description
This is a package deal of a Rastellium Zigzag oyster and a SeaBiscuit. These fossils come from the Mahajanga River Basin of Madagascar. Rastellium oysters are a now extinct branch of oysters that are named after the interlocking "teeth". Often touted as a "Biting oyster", these teeth actually weren't used to bite any prey, instead they were filter feeders like most modern oysters and clams. The Sea Biscuit is an old Echinoderm who still has relatives today.
Will combine multiple orders from us.
