Preserved material of "Rapator ornitholestoides", BMNH R3718, either the first metacarpal or the first phalanx of the first digit. On the top row, left to right: dorsal, ventral, medial, and lateral; on the bottom row: distal and proximal views. The bone measures 7cm along it's length, though von Huene's measurment is not based on a particular axis that can be verified from figures. It is proximally 4.5cm wide, 4cm wide distally, and in the middle it is 2.5cm.
