Haasiasaurus

Polcyn et al. 2003

Haasiasaurus is an extinct genus of early mosasauroid. The genus contains a single species, H. gittelmani, which was found in Cenomanian to Turonian rocks near Ein Yabrud, in the Palestinian West Bank, approximately 20 kilometres (12 mi) north of Jerusalem. It was named in honour of the palaeontologist Georg Haas, replacing the original name Haasia which was preoccupied by a millipede. Haasiasaurus was one of the oldest mosasauroids, measuring 1 metre (3.3 ft) long. The genus potentially represents a chimera, since the cranial and postcranial material were not found in association.
