sinopterus

My restoration of the weird azhdarchoid Tupandactylus. This drawing is already on Tumblr, but I wanted to share the original one.

Sinopterus (“Chinese wing”)

  • Temporal range: Early Cretaceous, 120 Ma
  • Fossil location: Jiufotang Formation (China)
  • Known species: S. dongi, S. jii

From Wikipedia:

Sinopterus is known for its proportionally large skull, which has a birdlike pointed beak, a long bony crest that starts with a tall premaxilla and goes back along the middle of the skull to form a point overhanging the rear of the skull, and its lack of teeth.

The chinese wing, Sinopterus (2003)

Phylum : Chordata
Class : Reptilia
Order : Pterosauria
Superfamily : Azhdarchoidea
Family : Tapejaridae
Subfamily : Tapejarinae
Genus : Sinopterus
Species : S. dongi, S. jii

  • Early Cretaceous (120 Ma)
  • 1,2 m long (size)
  • Jiufotang Formation, China (map)

Aside from being the first tapejarid discovered outside of Brazil,‭ ‬Sinopterus also represents one of the earliest and‭ ‬most complete.‭ ‬Sinopterus had a toothless bony beak and bony crest that runs from the premaxilla to the middle of the skull.‭ ‬The crest is then thought to extend upwards.‭ ‬Sinopterus is thought to have been an omnivore,‭ ‬with fruit perhaps forming an important part of its diet.

Another species,‭ ‬Sinopterus gui,‭ ‬is now thought to represent a younger individual of S.‭ ‬dongi.‭ ‬Some also consider that the smallest currently known pterosaur Nemicolopterus which also comes from the same Jiufotang Formation,‭ ‬may also represent a juvenile Sinopterus.‭ ‬As always,‭ ‬more fossils and study will be required for both of these pterosaurs.
