Named By: Geovane Alves de Souza, Marina Bento Soares, Luiz Carlos Weinschütz, Everton Wilner, Ricardo Tadeu Lopes, Olga Maria Oliveira de Araújo & Alexander Wilhelm Armin Kellner - 2021.
Classification: Reptilia, Dinosauria, Theropoda, Noasauridae.
Species: B. leopoldinae (type).
Size: Uncertain due to holotype being described from an immature individual, but possibly under a meter long.
Known locations: Brazil, Paraná - Goio-Erê Formation.
Time period: Unknown due to uncertainty of the date of the Fossil Formation at the time of description, but probably somewhere between the Aptian to the Campanian of the Cretaceous.
Fossil representation: Partial skull and Almost complete skeleton. Holotype is of an immature individual.
seems to be a bit of a strange dinosaur as even though it has been
considered to be a noasaurid theropod dinosaur, Berthasaura
a toothless beak. The description of Berthasaura
is not actually the
first time that a noasaurid theropod has been found without teeth,
is also toothless and is known from the Late Jurassic
period of China. Berthasaura however is even
further specialised with
its beak like form to its skull.
This casts immediate uncertainty as to what Berthasaura ate, as most other noasaurids seem to be dedicated carnivores. If Berthasaura was still a carnivore, it would perhaps be more likely to have swallowed small vertebrates like lizards whole, or picked at the carcasses of dead animals. Berthasaura might have even taken to herbivorous browsing, or followed an omnivorous lifestyle, eating whatever it could get. Only future discoveries with preserved stomach contents might be able to give a clearer picture.
The fossil site that Berthasaura is known from was a desert back in the Cretaceous.
