“apparently terminal.” Cope’s subsequent and more detailed descrip- 
tions ignored the second vertebra but added a third from another locality: 
“A second [sic] and much smaller vertebra from the pit that furnished the 
remains of Hypsibema crassicauda, belonged to a third individual, and 
possibly to this species” (Cope 1870). The “terminal” vertebra is now 
missing and the tentatively referred “second” vertebra, also missing, is at- 
tributed by us to a juvenile Hypsibema crassicauda. Lull and Wright (1942: 
145) cited as cotypes USNM 7190 and 7093, but since the latter specimen 
is labeled as having been collected by Berry and Stephenson at Phoebus 
Landing in 1907 it cannot be part of the type material; we take it to be a
