Fig. 3 Image of left pterygoid (A) of IVPP V 15001, holotype of Macrocnemus fuyuanensis and reconstructive sketch (B) of the pterygoids and surrounding bones The basioccipital, the pterygoid (in grey), and the ectopterygoid were taken from IVPP V 15001 and are to scale (the latter two were also mirrored for completion). The parabasisphenoid and the palatine were taken from PIMUZ T 1559 and rescaled (the latter also mirrored as well). Stippled lines indicate the outlines of the upper jawbones (premaxilla, maxilla and jugal) and the vomers. The outline and dentition of the vomer is only incompletely preserved in IVPP V 15001. Note that the posteromedial gap between pterygoid and tooth-bearing margin of the palatine in the sketch might be a preservational artifact Abbreviation: pt-qr. quadrat ramus of pterygoid; other abbreviations see Fig. 2
