The nearly complete AMNH FR 30587 skeleton anchors the anatomical comparison; suchian placement and convergence are character-matrix interpretations, not ancestry or identical ecology.

topology · mediumAMNH FR 30587 preserves a nearly complete edentulous, gracile archosaur skeleton that the published character analysis places within Suchia; resemblance to ornithomimid theropods is interpreted as convergence, not shared ancestry or identical ecology.
