Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. S. Morgan and N. J. Czaplewski 2023 | All characters pertain to the holotype M1, the only tooth represented in the hypodigm of Karstopteryx gunnelli. The M1 has a greatly reduced anterolabial portion of the tooth, including the stylar shelf labial to the paracone, but has a well developed, rounded parastyle at the anterolabial terminus of the paracingulum. The preparacrista is very short and oriented anteriorly. A weakly concave indentation is present in the metafossa labial to the metacone, not a sharply V-shaped indentation. The metacone is taller than the paracone. The paracingulum curves posterolingually from the parastyle to the protocone. The weak hypocone is not separated from the protocone by a distinct notch in the postprotocrista. A paraloph and metaloph are absent. The trigon is triangular in shape not squarish. The talon has rounded lingual, labial, and posterior margins and lacks a deep, central pit. |
