Pterosaur - Fossil matrix - Sinopterus - 72 cm - 63 cm

Sinopterus — The Crested Master of the Air

Sinopterus is a member of the Tapejaridae family, a group of toothless pterosaurs. Its defining features include a large preorbital fenestra and a cranial crest developed from the upper jaw, extending from the front to the back of the skull. In pterosaurs, such crests likely served multiple functions, including species recognition, sexual selection, thermoregulation, and social signaling.

The bones of this specimen are black and lustrous throughout, indicating excellent mineralization. One of the key features of Sinopterus—the cranial crest—is also exceptionally well preserved, as shown in the photos. The length from the tip of the beak to the tip of the crest measures 19 cm, making it a large individual for this species.

The matrix measures 72 × 63 × 2 cm, and the reverse side has been reinforced, so there is no need to worry about damage during transportation.

This specimen is preserved in its original burial posture. As flying reptiles, pterosaurs typically had lightweight and fragile bones, making their preservation over tens of millions of years an exceptionally rare occurrence. In most cases, even a complete skull preserved together with the torso on the same matrix is considered uncommon.

However, this specimen goes far beyond that: the phalanges, claws, and the tip of the wing finger are all perfectly preserved, and the entire body shows no signs of restoration. Without doubt, this is a well-preserved pterosaur specimen.

I sincerely recommend this perfectly preserved and meticulously prepared pterosaur fossil to all collectors.
