Figure 1. Characters 1 and 2 and their postulated states. Char. 1. Premaxilla, rostrum, length relative to the maxilla: B, longer – 1.0; A, C, D, shorter – 1.1. Lr is the length of the rostrum and pr is its caudal projection over the maxilla; an arrow marks the caudal margin of the maxillary process of the nasal (see text). Char. 2. Premaxilla, nasal process, form: A, not arched – 2.0; B, smoothly arched – 2.1; C, strongly arched – 2.2; D, developed into a high crest – 2.3. Rostrum of (A) Rhinocrypta lanceolata (MCP 2395), (B) Liosceles thoracicus (MPEG O-3953), (C) Eugralla paradoxa (MCP 2398) and (D) Acropternis orthonyx (QCAZ 3723) in lateral view. Not to scale.
