Pterodactylus is known from over 30 fossil specimens, and though most belong to juveniles, many preserve complete skeletons. [17] [23] Pterodactylus antiquus was a relatively small pterosaur, with an estimated adult wingspan of about 1.04 meters (3 ft 5 in), based on the only known adult specimen, which is represented by an isolated skull.

The collection's final selling price of 700 ... fragment of an upper jaw with teeth, ... in 1857 as belonging to the pterosaur Pterodactylus crassipes by H. v. Meyer ...
A peculiar family within this group is the Ctenochasmatidae, which most of the members had very distinguishing teeth that were lined within their elongated snouts. [8] A genus called Pterofiltrus only had 112 teeth, but these teeth cover about 55.8% of the total skull, and the skull itself measured about 208 millimeters (8.2 in) in length. [9]
If you thought teeth were only worth a couple bucks from the tooth fairy, think again. On a brand-new episode of "Antiques Roadshow" Monday, a Fred Myrick scrimshaw tooth got a price tag that ...
However, in 2010, Brian Andres re-defined the group as a stem-based taxon in his dissertation, [10] and then formalized the definition in 2014 as all pterosaurs more closely related to Pteranodon longiceps than to Pterodactylus antiquus. [3] The slightly more exclusive group Ornithocheiroidea was re-defined in 2003 by Alexander Kellner.
Gallodactylidae is a group of pterosaurs within the suborder Pterodactyloidea.Gallodactylids differed from other related pterosaurs in several distinct features, including fewer than 50 teeth present only in the jaw tips, and rounded crests present on the rear portion of the skull and jaws but not near the ends of their snouts.
For example, Pterodactylus fittoni shares with C. cuvieri a low snout tip, the lack of a front expansion at the end of the snout, a palate that is curved towards the back, as well as a palatal ridge extending hindward until the third pair of tooth sockets, though the latter feature is only shared with C. cuvieri if the first preserved pair of ...
The snout curved slightly upward and was rounded at the tip, and the teeth were restricted to the front half of the jaws. [6] The smallest species, Ctenochasma elegans, had a maximum wingspan of 1.9 metres (6.2 ft) as an adult. [9] Ctenochasma is distinguished by
