Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Feduccia 1974 | Distal end (21.7 mm) of left tibiotarsus similar to that of Neophrontops americanus L. Miller (see Miller, 1916, and Howard, 1932,
for generic diagnosis), but differing as follows: anterior intercondylar fossa relatively deeper; tendinal groove relatively broader; internal ligmental prominence relatively more pronounced; external ligamental prominence relatively less pronounced; shaft relatively more robust at condylar area; external condyle notched at its union with shaft (running smoothly into shaft in N. americanus). N. slaughteri is similar in size to the largest of the tibiotarsi of N. americanus, measured as follows: breadth of distal end of tibiotarsus-15.0 mm in N. slaughteri and 14.3 +/- 0.8 (standard deviation) (range 13.2 to 15.0) in 6 N. americanus; depth of distal end of tibiotarsus -11.4 in N. slaughteri and 11.0 +/- 0.5 (range 10.2 to 11.3) in 6 N. americanus. |
