Liaoningopterus, sometimes misspelled as "Liaoningopteryx", was a
, China.The genus was named in 2003 by Wang Xiaolin and Zhou Zhonghe. The type species is Liaoningopterus gui. The genus name is derived from Liaoning and a Latinized Greek pteron, "wing". The specific name honors Professor Gu Zhiwei, an invertebrate specialist who has pioneered the study of the Jehol Biota.
Description
The genus is based on
Meanwhile, the longest tooth in the lower jaw of Liaoningopterus has a length of 41 millimeters (1.6 in). Tooth length in the specimen is very variable, which the authors explained by the presence of recently erupted replacement teeth. There were twenty pairs of teeth in the upper jaws and thirteen or fourteen pairs in the lower jaws. The preserved cervical vertebra has a centrum length of 46 millimeters (1.8 in) and a centrum height of 34 millimeters (1.3 in). From the wing bones pieces of the first phalanx can be recognized which had an estimated total length of about 50 millimeters (2.0 in). The authors described Liaoningopterus as being probably a piscivore, due to the long, pointed snout.[1]
The size is estimated at 5 m (16 ft) in wingspan and 20 kg (44 lb) in body mass.[2][3]
