Campylognathoides liasicus pterosaur skeleton in matrix 

It wasn't until 1928 that paleontologist Embrik Strand realized that the name of Campylognathus was already taken and he renamed the genus to Campylognathoides

Cast of the Pittsburgh specimen of Campylognathoides liasicus

We have a limited number of this cast (which is no longer being made). It comes from a private collection.

We will repaint, or touch up cast as needed prior to shipping.

In 1858 Friedrich August Quenstedt named a new species of Pterodactylus: P. liasicus. It was based on a fossil, holotype GPIT 9533, consisting of some wing bones, found on the Wittberg near Metzingen in layers dating from the early Toarcian. The specific name referred to the Lias. Quenstedt thought he had identified long metacarpals in the wing, concluding that the new species was therefore not belonging to more basal genera, like the long-tailed Rhamphorhynchus.

In 1893 commercial fossil collector Bernhard Hauff sr. discovered a skeleton of a large pterosaur near Holzmaden. In 1894 Felix Plieninger based a new genus on this specimen: Campylognathus. The genus name is derived from Greek kampylos, "bent", and gnathos, "jaw", in reference to the bent lower jaw. The type species is Campylognathus zitteli. The specific name honours Alfred von Zittel. The holotype is SMNS 9787.

In 1897 Hauff prepared another specimen that eventually in 1903 was acquired by the Carnegie Museum of Natural History at Pittsburgh. This fossil, CM 11424, is due to its completeness the best source of information about the genus.

In 1901 Plieninger for the first time studied P. liasicus and discovered that Quenstedt had mistaken the, in reality short, metacarpal, for a coracoid, meaning it was a basal pterosaur. In 1906 Plieninger referred P. liasicus and the Pittsburgh specimen to Campylognathus, though not yet establishing the specific status of each of the three exemplars. In 1907 however, Plieninger recognised a second species of Campylognathus: C. liasicus, to which CM 11424 was referred also.

Norwegian entomologist Embrik Strand discovered in the 1920s that the name Campylognathus had previously been used for the African bug Campylognathus nigrensis, a genus of the Heteroptera named in 1890. As the name was thus preoccupied, he renamed the pterosaur Campylognathoides in 1928. During the twentieth century new finds have brought the number of known specimens to about a dozen.

According to a study by Kevin Padian there are eight cervical vertebrae, fourteen dorsals, four or five sacrals and up to 38 caudal vertebrae. The tail base is flexible with about six short vertebrae; behind them the caudals elongate and are stiffened by very long extensions allowing the tail to function as a rudder Campylognathoides liasicus

Campylognathoides liasicus Jurassic skeleton in matrix resin cast.

Campylognathoides ("curved jaw", Strand 1928) is a genus of pterosaur, discovered in the Württemberg Lias deposits (dated to the early Toarcian age), the first specimen consisting of wing fragments. Further better preserved specimens were found in the Holzmaden shale and it was based on these specimens that Felix Plieninger erected a new genus

Compared to its contemporary from the same layers Dorygnathus, the snout on this genus is relatively short, though the skull is still in general elongated, be it much lighter built. The large eye sockets, placed low in the skull above a narrow jugal, have caused some researchers to speculate that Campylognathoides had especially acute vision, or possibly even a nocturnal lifestyle. The back of the skull is relatively high and flat, with a sudden downturn just in front of the eyes. The snout ends in a slender point curving a bit upwards at its very end. A large part of the snout is occupied by long bony nares. Below them a small triangular skull opening, the fenestra antorbitalis is present.

Reflecting the more shallow snout, the teeth of Campylognathoides are also short and not at all laniaries or fang-like as in the markedly heterodont Dorygnathus. They are conical and recurved but have a broad base with the point bevelled off from the inside forming a sharp and strong cutting surface. In the upper jaw there are four rather widely spaced teeth in the praemaxilla gradually increasing in size from the front to the back; the fourth pair of teeth is the largest. Behind them are ten smaller teeth in the maxilla, gradually decreasing posteriorely. In the lower jaw there are twelve to fourteen teeth present in C. liasicus, sixteen to nineteen in C. zitteli. The largest total number is thus 66.

This cast measures 30 x 17 inches.  If you see a smaller cast for sale it is a bootleg.  We own the original mold.
