A new crocodilian, Hassiacosuchus kayi, from the Bridger Eocene beds of Wyoming.
Open accessAbstract
During the field season of 1936 an unusually well preserved fossil crocodilian skeleton was discovered in the Bridger Eocene Beds near Mountain View, Wyoming, by Mr. J. LeRoy Kay of the Carnegie Museum.This specimen consists of a nearly perfect skull with jaws and a practically complete postcranial skeleton with the dorsal scutes in place.The skeleton now comprises Carnegie Museum No. 9600.It was referred to me for study by Mr. Kay.I wish to express my appreciation for the privilege of describing this fine specimen.

The historical range of adult bite-force values for Crocodylia as a whole may have spanned from 628 N to 102,803 N, in extinct Procaimanoidea kayi and Deinosuchus riograndensis respectively.
“In addition the historical range of adult bite-force values for Crocodylia as a whole may have spanned from 628 N to 102,803 N (141 to 23,102 lbs; in extinct 0.8 m TL, 1.99 kg Procaimanoidea kayi [27] and 11 m TL, 3,450 kg Deinosuchus riograndensis [28], respectively; see Materials and Methods).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
