Taxonomic list

• A large quantity of material was collected from the extensive outcrops around Alhadas by the geologist Paul Choffat (1849–1919) and his team as they mapped the area. It is possible that MG33 was collected during those expeditions. Alhadas has yielded several other vertebrate remains including ichthyosaurs and fishes, and a new fossil fish locality was identified during a prospecting trip in November 2007.
