On a special extended stand, the drill was used to sample another pelycosaur. A well earned BBQ after a challenging but successful day! Courtesy of Johannes Richter (geol. survey), Martin Sander, Jörg Schneider, Christen Shelton, Nico Richter, and Marcel Hübner.

documentation of early amniote fossils

casts of early amniote fossils

For my planned dissertation some Permian amniote fossils have to be cast. The soft bones have left natural casts in the limestone that can be documented as the original shapes when molded with silicone.
