“…The area of the new dinosaur tracksite is located between Boca do Chapim and Praia do Areia do Mastro sites. Those localities are situated at the coastal cliffs, about 2 km to the north of Cape Espichel (Figure 1) Formation, dated as middle Barremian (e.g., Rey, 1972;Manupella et al, 1999;Aillud, 2001;Dinis et al, 2008;Rey et al, 2003;Figueiredo et al, 2020) ( Figure 2). The Areia do Mastro Formation comprises brackish-water estuarine sandstones and silty marls to marine carbonates (Rey, 1972(Rey, , 1992Manupella et al, 1999;Rey et al, 2003).…”

“…The dinosaur tracks were found in three top beds of the Areia do Mastro Formation, which can be attributed to the lowermost Barremian (Rey, 1972;Manupella et al, 1999;Rey et al, 2003); remains of marine turtles and abundant large naticid gastropods were also found. The dinosaur trampled beds consist of bluish-grey limestones showing a nodular texture due to a high invertebrate bioturbation (mainly Thalassinoides suevicus) typical of an intertidal to subtidal lagoon environment (Neto de Carvalho et al, 2007), and that suggests that the dinosaurs crossed an intertidal environment (Figueiredo et al, 2017(Figueiredo et al, , 2020.…”

We present a new tracksite with multiple dinosaur tracks from the lowermost Barremian (Lower Cretaceous) of the Cape Espichel (Sesimbra, Portugal). The tracks are localized on three beds on the top carbonate beds of the Areia do Mastro Formation. Those bioclastic, nodular limestones were deposited in a very shallow subtidal-intertidal, restricted lagoon environment. The track surfaces are very dinoturbated, with a substantial number of tracks. Several tracks assign to sauropods, ornithopods and theropods dinosaurs were recorded. Due to heavy bioturbation and the preservation conditions, it is not possible to define trackways; some preliminary work done on the tracks could disclose some behaviours of their producers. Several species of carnivore and herbivore dinosaurs crossed that large area at different times. Herbivores may have used the lagoon margin as passage between feeding spots, while carnivores frequented the area to hunt in groups or individually.

“…Other isolated teeth comprise the vast majority of pterosaur fossils from Portugal, and were recovered from the Areia do Mastro locality of the lower Barremian Papo Seco Formation of Cabo Espichel. They were assigned to the Ornithocheiridae and to the Ctenochasmatoidea ( Figueiredo et al, 2020 , 2022 ). From the Andrés fossil site of the Kimmeridgian Alcobaça Formation, isolated teeth were also attributed to Pterosauria indet.…”

A new gnathosaurine (Pterosauria, Archaeopterodactyloidea) from the Late Jurassic of Portugal

An incomplete, yet remarkably-sized dentated rostrum and associated partial cervical vertebrae of a pterosaur (ML 2554) were recently discovered from the Late Jurassic (Late Kimmeridgian-Early Tithonian) Lourinhã Formation of Praia do Caniçal, of central west Portugal. This specimen exhibits features such as a spatulated anterior expansion of the rostrum, robust comb-like dentition, and pronounced rims of the tooth alveoli, indicating gnathosaurine affinities. Based on its further unique tooth and dentary morphology, a new genus and species, Lusognathus almadrava gen. et spec. nov., is proposed, making this the first named pterosaur species found within Portugal. The presence of this taxon adds yet another element to the fluvio-deltaic lagoonal environment that has been suggested as representative of the Lourinhã Formation in the Late Jurassic, further contributing to the diversity and distribution of gnathosaurines worldwide.
