Reconstruction of the life aspect of Lusovenator santosi (Author: Carlos de Miguel Chaves for the GBE)
A new species of theropod dinosaur found in Portugal pushes back the date of carcharodontosaurids in Europe by 20 million years.
Summary Points
A paleontologist team led by Elisabete Malafaia identified a new species of carnivorous dinosaur in the Upper Jurassic of Portugal.
Lusovenator santosi: The genus name Lusovenator means Hunter from Lusitania. The species name santosi is a tribute to an amateur paleontologist who has discovered a large number of dinosaur sites throughout Portugal.
Lusovenator santosi is the earliest occurrence of carcharodonstosaurid dinosaurs in Europe.
The fossils were collected over the past 20 years from beaches in the Lusitanian Basin along the Portuguese coast

A paleontologist team led by Elisabete Malafaia identified a new species of carnivorous dinosaur in the Upper Jurassic of Portugal. The new species called Lusovenator santosi is based on fossils collected over the past 20 years from beaches in the Lusitanian Basin along the Portuguese coast. This new species of lived between 146 and 153 million years ago and was around 3.5 meters in length.
Initially the fossils were thought to be from the well-known Jurassic theropod called Allosaurus, however this more detailed study shows they are from a group of dinosaurs called carcharodontosaurids.
Carcharodontosaurids are a group of carnivorous theropod dinosaurs. In the Cretaceous, they became some of the largest predators on the planet. A well-known carcharodontosaurus is Carcharodontosaurus saharicus from the Kem Kem beds of Morrocco. This large theropod is similar in size to T. rex. Another well-known carcharodontosaurus is Gigantosaurus carolinii of South America which is the largest theropod dinosaur yet found.
Previously, the oldest known carcharodontosaurid fossils came from Tanzania in Africa from the Upper Jurassic. This new species from Portugal is the same age as the Tanzania specimens and constitutes the first evidence of carcarodontosaurids in the Upper Jurassic of the northern hemisphere.
This is the first time a carcharodontosaurus this old was found in the northern hemisphere. This new research shows carcharodonsotaurids were present in the Iberian Peninsula at least 20 million years earlier than previously thought. This has many implications to the evolution of the dinosaurs and ecosystems in not just the Iberian Peninsula but how and when they migrated between Europe and North America.
Until this discovery, the Upper Jurassic theropod fauna of Portugal consisted of closely related dinosaurs species from the Morrison Formation of North America, such as Ceratosaurus, Torvosaurus, and Allosaurus. Carcharodontosaurs are not found in North America until the Lower Cretaceous.
The name Lusovenator, means hunter from Lusitania. The species name is a tribute to Jose Joaquim Dos Santos, an amateur paleontologist who has discovered a large number of dinosaur and other fossil sites throughout Portugal.
A detailed description of the fossils were published in the Journal of Vertebrate Paleontology.
