Abstract

The Australian pterosaur record is poor by world standards, comprising fewer than 20 fragmentary specimens. Herein, we describe the new genus and species Ferrodraco lentoni gen. et sp. nov., based on the most complete pterosaur specimen ever found in Australia, and the first reported from the Winton Formation (Cenomanian–lower Turonian). The presence of premaxillary and mandibular crests, and spike-shaped teeth with subcircular bases, enable Ferrodraco to be referred to Anhangueria. Ferrodraco can be distinguished from all other anhanguerian pterosaurs based on two dental characters: the first premaxillary and mandibular tooth pairs are small; and the fourth–seventh tooth pairs are smaller than the third and eighth ones. Ferrodraco was included in a phylogenetic analysis of Pterosauria and resolved as the sister taxon to Mythunga camara (upper Albian Toolebuc Formation, Australia), with that clade occupying the most derived position within Ornithocheiridae. Ornithocheirus simus (Albian Cambridge Greensand, England), Coloborhynchus clavirostris (Valanginian Hastings Sands, England), and Tropeognathus mesembrinus (upper Aptian–lower Albian Romualdo Formation, Brazil) were resolved as successive sister taxa, which suggests that ornithocheirids were cosmopolitan during the Albian–Cenomanian. Furthermore, the stratigraphic age of Ferrodraco lentoni (Cenomanian–lower Turonian) implies that anhanguerians might have survived later in Australia than elsewhere.

Highlights

Pterosaurs are known from Mesozoic strata on every continent, with their fossil record spanning the Late Triassic–end Cretaceous[1]
Briefly describe, a new anhanguerian pterosaur species from the Cenomanian–lower Turonian Winton Formation of Queensland, northeast Australia. This specimen — discovered in April 2017 by one of the authors (RAE) — is the first pterosaur reported from the Winton Formation, and is the most complete pterosaur ever found in Australia
Phylogenetic analysis indicates that Ferrodraco (Fig. 8) and Mythunga belong to the Ornithocheirinae sensu Andres et al.[19], with two pterosaurs from England — Ornithocheirus simus from the Albian Cambridge Greensand and Coloborhynchus clavirostris from the Valanginian Hastings Beds — as successive sister taxa within that clade

Summary

Introduction

Pterosaurs are known from Mesozoic strata on every continent, with their fossil record spanning the Late Triassic–end Cretaceous[1]. Pterosaurs are rare in Australia, with their fossil record restricted to the Cretaceous and comprising isolated and fragmentary bones from Queensland[3,4,5,6,7,8,9], New South Wales[10], Western Australia[11,12] and Victoria[13,14]. Briefly describe, a new anhanguerian pterosaur species from the Cenomanian–lower Turonian (lower Upper Cretaceous) Winton Formation of Queensland, northeast Australia. This specimen — discovered in April 2017 by one of the authors (RAE) — is the first pterosaur reported from the Winton Formation, and is the most complete pterosaur ever found in Australia
