Prettige feite

Petrobrasaurus is known from a partial skeleton that includes teeth, vertebrae, ribs, leg bones, and even sternal plates.1

Its name honors the Petrobras oil company, which helped preserve fossils in the area.1

This dinosaur lived about 89 to 83 million years ago, during the Late Cretaceous period.3

Its teeth were cylindrical and pencil-like, perfect for a plant-eating diet.1

The fossils were found near an oil well called PH 1597, in the Puesto Hernández oil field.1

Vir dino-kenners

Wetenskaplike naam: Petrobrasaurus
Benoem deur: Filippi et al. 20114
Groep: Langnekke
Familie / klade: Titanosauria4
Klassifikasie: Sauropodomorpha > Sauropoda > Titanosauria > Macronaria4
Ouderdom van die rotse: 90 tot 84 miljoen jaar (Coniacian / Santonian)4
Rotsformasies: Plottier4
Lande: Argentinië4
Fossielrekords: 1 in The Paleobiology Database4
Ontdekking: Petrobrasaurus was named in 2011 by Leonardo Filippi and colleagues, based on a partial skeleton found in the Plottier Formation of Argentina.2 3
Steeds omstrede: Scientists are not sure exactly which group of titanosaurs Petrobrasaurus belongs to; some think it might be related to Lognkosauria, but it is still considered Titanosauria incertae sedis (uncertain placement).1
