Pterosauria - Rhamphorhynchoidae - Dimorphodontoidea - Anurognathidae
The Anurognathids formed a group of small pterosaurs strongly related to the Dimorphodontids. The tail was shorter, the legs long and good develped, the neck was short, the snout and nostrils smaller, the beak broad and the teeth small and peg-like. Ancestors: Dimorphodontidae
Distribution: Laurasia (Germany and Kazachstan)
Timeperiod: Kimmeridgian-Titonian, Late Jurassic
Size: Skulll 3-5 cm. Spanwide 30-50 cm.
Diet: Insects and small vertebrates
Info: Parafamily: Aunrognathidae Kuhn, 1967 = Anurognathinae Nopcsa, 1928
Describer: Döderlein, 1923
Distribution: Eichstätt limestone, Germany
Timeperiod: Late Jurassic
Size: Skull length = 3 cm in length Spanwide 50 cm.
Info: = Anuroganthus Young, 1964 [sic] Anurognathus from the Late Jurassic of Germany was one of the last Rhamphorhynchoidae, this is reflected by the abcense of a long tail, with a spanwide of 30 cm. this is one of the smallest known pterosaurs. The skull was relatively small and the jaws gave space to small blunt teeth.
Describer: Riabinin, 1948
Distribution: Karatau Mountains, Kazachstan
Timeperiod: Late Jurassic
Size: Skull length = 4.8 cm. Wingspan = 50 cm.
Info: Known from two disarticulated and crushed specimens. This pterosaur has a broad skull and short, widely-spaced teeth. The wing claws are large. The toe bones are very short close to the foot, like Sordes and other anurognathids. The sternum is very broad and not very deep.
Describer: Ji S. & Ji Q., 1998/Yin & Zeng, 1995
Distribution: Chaomidianzi Formation, Beipiao City, western Liaoning Province, China
Timeperiod: Tithonian, Late Jurassic
Size: Skull length = 3 cm. Overal length = over 12 cm. Wingspan = 48 cm.
Info: = ( Dendrorhynchus curvidentatus = tree beak, curved teeth) D.curvidentatus horiginally described as a rhamphorhynchoid has a short, lightly constructed face a short, thin fourth wing finger phalanx, large manual claws, appressed metatarsals and a short thin tail.
Describer: Colbert, 1969
Distribution: western Cuba
Timeperiod: Oxfordian, Late Jurassic
Info: Nesodactylus = Nesodon Jensen & Ostrom, 1977/Owen, 1840 [sic] N. hesperius Colbert, 1969 = Nesodon hesparius Jensen & Ostrom, 1977 [sic]
This genus is listed in an as-yet-unnamed new family with Comodactylus by Unwin (in Benton, 1993). Referred to this family provisionally.(Nesodactylus hesperius =island finger of the west)
Discovered in the lab at the American Museum in the 1960s when a chunk of Jurassic limestone collected 50 years earlier was being prepared in acid. The length of the first wing finger phalanx indicates it is an anurognathid.
