Lonchodraco is a genus of lonchodraconid pterodactyloid pterosaur from the Late Cretaceous of southern England.

In 1850, Richard Owen, considering the species not to have been particularly large, and renamed it into Pterodactylus conirostris; the specific name meaning "cone-snouted", which was based on the conical snout of specimen NHMUK PV 39412.

Therefore, they created a new genus Lonchodraco, combining Greek λόγχη, lonchē, "lance", with Latin draco, "dragon".

[1] Rodrigues and Kellner considered NHMUK PV 39412 to be the lectotype of Lonchodraco giganteus, after a choice by Peter Wellnhofer in 1978.

The type specimen of Ornithocheirus oweni Seeley 1870, CAMSM B 54439, was synonymized with microdon by Unwin (2001),[11] and Rodrigues & Kellner (2013) agreed with this synonymy.

In 1870, Seeley had realised that the generic name Ptenodactylus had been preoccupied and renamed the species into Ornithocheirus machaerorhynchus.

They established one of these: the tooth sockets are elevated relative to the palate and lower jaw edge.

Later in their analysis however, Rodrigues & Kellner considered the definition of Lonchodraconidae to be more or less synonymous to that of Lonchodectidae, however, they stated that Lonchodectes is a nomen dubium and therefore should not be included in the group.
