Campylognathoides liasicus (Pterodactylus liasicus Quenstedt 1858, Campylognathoides liasicus Plieninger 1907) CM 11424, specimen C3 in the Wild (1975 catalog), Early Jurassic, ~180 mya, was derived from a sister to Nesodactylus and phylogenetically preceded Rhamphorhynchus intermedius no. 28.
Distinct from C5, the skull of C. liasicus is a robust overall with a dorsally curved premaxilla and relatively smaller fangs. The “lacrimal” identified by Wellnhofer (1974) is the inverted postorbital. The “ectopterygoid” is the missing articular. The right “pterygoid” is the right quadrate. The multi-branched “pterygoid” is a pair of overlapping ectopalatines. Wellnhofer’s curved bone identified with a “?” is the right pterygoid and both anterior pterygoids appear below the layered ectopalatines. The vom
Distinct from Nesodactylus, the cervicals did not decrease cranially and the neural spines were not as tall. The sternal ribs were slender. The tail was not as long or robust.
Each side of the sternal complex was anteriorly convex.
The ischium was broad. The long-stemmed prepubes were fused ventrally resulting in a prepubic belt with two circular perforations. This appears to be the largest prepubis relative to the torso among pterosaurs. Pedal digit III, sans the ungual, was longer than the others.
Following the C3 specimen is a phylogenetic size reduction from Rhamphorhynchus intermedius no.28, to the unnumbered BMM specimen to the no.10 specimen. |
