prey. This idea was later criticised for lack of evidence; Thalassodromeus has since been found to have had strong jaw musculature, and may have been able to kill and eat relatively large prey on the ground. The limb proportions of related species indicate that it may have adapted to fly in inland settings, and would have been efficient at moving on the ground. Thalassodromeus is known from the Romualdo Formation, where it coexisted with many other types of pterosaurs, dinosaurs and other animals. History of discovery The first known specimen of this pterosaur (an extinct order of flying reptiles) was collected in 1983 near the town of Santana do Cariri in the Araripe Basin of northeastern Brazil. Found in outcrops of the Romualdo Formation, it was collected over a long period in several pieces. The specimen (catalogued as DGM 1476-R at the Museu de Ciências da Terra) was preserved in a calcareous nodule, and consists of an almost-complete, three-dimensional skull (pterosaur bones are often flattened compression fossils), missing two segments of the bottom of the skull and mandible and the front of the lower jaw. The left jugal region and right mandibular ramus (half of the mandible) are pushed slightly inward. The skull was first reported in a 1984 Italian book, and preliminarily described and figured in 1990 by palaeontologists Alexander Kellner and Diogenes de Almeida Campos. Although the pieces of skull had been divided between museums in South and North America, they were assembled before 2002. In 2002, Kellner and Campos described and named the new genus and species Thalassodromeus sethi, skull DGM 1476-R being the holotype specimen. The generic name is derived from the Ancient Greek words and , meaning "sea runner" in reference to the animal's supposed skim-feeding behaviour. The specific name refers to the Egyptian god Seth. The specimen was not fully prepared at the time of this preliminary description. The original describers chose the name sethi because the crest of this pterosaur was supposedly reminiscent of the crown worn by Seth, but the palaeontologists André Jacques Veldmeijer, Marco Signore, and Hanneke J. M. Meijer pointed out in 2005 that the crown (with its two tall plumes) was typically worn by the god Amon (or Amon-Ra) and his manifestationsnot by Seth. In 2006, palaeontologists David M. Martill and Darren Naish suggested that Thalassodromeus was a junior synonym of the related genus Tupuxuara, which was named by
