Aymberedactylus (meaning "small lizard finger") is a genus of tapejarid pterosaur from the Early Cretaceous Crato Formation of Brazil.

[1] The name Aymberedactylus is derived from the Tupi word aymbere ("small lizard") and Greek daktylos ("finger"), and the specific name refers to the Brazilian state of Ceará, which it was discovered in.

[1] Aymberedactylus can be identified as a tapejarine tapejarid from the holotypic jawbone due to its toothlessness, slightly downturned dentary symphysis which accounts for half of the total length of the jaw, and a small crest on the bottom of the dentary (which was incompletely preserved).

Small neurovascular foramina on the symphysis indicates the likely presence of a horned sheath over the tip of the jaw, which is also seen in Tupandactylus.

[1] The preserved specimen of Aymberedactylus would have had a wingspan of approximately 2 metres (6 ft 7 in), typical of tapejarids.
