Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. M. Appleby 1979 (Leptopterygius) | "As for the single species in this genus." | |
| R. Motani 1999 | Overbite present but not remarkable; manual digits short, usually with six or less phalanges in the longest digit; notch in radius but not in other leading-edge elements. | |
| M. W. Maisch and A. T. Matzke 2000 | "Skull with long and exceedingly slender snout but no distinct overbite, orbits large but directed largely laterally and only slightly anteriorly, forefins without notches except in radius, with few usually rounded and rather widely spaced phalanges, hindfins less than two thirds of the length of the forefins." | |
| C. Ji et al. 2016 | Orbit large; angular lateral exposure at its maxi- mum depth much deeper than surangular; coronoid region slightly elevated; root of tooth without strong striations; humerus with constricted shaft, widely expanded distally with leading edge facet that is usually prominent; radioulnar foramen present; phalanges rounded and well spaced distally; forelimb longer than but less than twice hind limb; femur medially constricted, form- ing a slender shaft region; pubis and ischium separate or partially fused. |
