It is the metatarsal bone

Risnes 2005

Parent taxon: Homalonotidae according to P

It is a piece with a size that exceeds that of the average for its species

The basin has a so great continuity in its stratigraphic record that both the Upper Cretaceous as well as the two first epochs of the Paleogene (Paleocene and Eocene) can be studied

20859 - Pink Cobaltoan Calcite Crystals on Matrix - Bou Azzer Mine (South Morocco) Claw It is the metatarsal boneCalcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". The Cobaltoan calcite is a variety of calcite containing Co2+ replacing Ca, that's the reason for its pretty pink color.
