Draconyx

Draconyx

Draconyx (meaning "dragon claw") is a genus of dinosaur from the Late Jurassic. It was an ornithopod which lived in what is now Portugal. It was found in Lourinhã, in 1991, and described by Octávio Mateus and Miguel Telles Antunes in 2001.

The type species, known from only partial remains, is D. loureiroi, in honour of João de Loureiro, a Portuguese jesuit priest, a pioneer in Portuguese palaeontology.

Material

The holotype (ML 357) consists of two maxillary teeth, three caudal centra, one chevron, distal epiphysis of right humerus, one manual phalanx, three manual unguals, distal epiphysis of right femur, epiphysis of tibia and fibula, astragalus, calcanaeum, three tarsals, four metatarsals and pedal phalanges. It was found on Vale de Frades.

A femur (ML 434), found on Praia do Caniçal, has also been referred to this taxon.

Systematics

According to Mateus and Antunes (2001), Draconyx loureiroi is a member of Iguanodontia, more specifically Camptosauridae, based on the maxillary teeth, which have a strong vertical primary ridge on the distal side of the labial crown, and the femur, which is curved and has a prominent lesser trochanter.
