Angaturama

Say it: an-gah-too-RAH-mah

Name means: “noble”1

Ate: MeatSpinosaursEarly Cretaceous

Angaturama was a meat-eating dinosaur that lived about 115 million years ago in what is now Brazil. It had a long, narrow snout with a rosette of teeth at the tip, perfect for catching fish. This dinosaur was one of the smallest spinosaurids, but it was still a fierce hunter.1

Fun facts

Angaturama's snout tip was shaped like a rosette, with long teeth that interlocked to trap slippery fish.1

Its nostrils were placed far back on the snout, which helped it breathe while its mouth was underwater.1

Angaturama had a thin crest on top of its head where strong neck muscles attached, helping it snap its jaws quickly.1

This dinosaur lived in a tropical coastal lagoon environment, surrounded by dry land with plants like cycads and conifers.1

Angaturama is known only from a snout tip, but a replica skeleton was built using other bones from the same formation and is displayed in Brazil.1

Some scientists think Angaturama might be the same species as another spinosaur called Irritator, but others disagree.2 1

For dino experts

Scientific name: Angaturama
Named by: Kellner and Campos 19964
Group: Spinosaurs
Family / clade: Spinosauridae4
Classification: Theropoda > Spinosauridae4
Age of the rocks: 120 to 113 million years (Aptian)4

Discovery: Angaturama was named by Brazilian paleontologists Alexander W. A. Kellner and Diogenes de Almeida Campos in February 1996. The fossil snout tip was found in a limestone nodule from the Romualdo Formation in Brazil.1 3
Still debated: Scientists are not sure if Angaturama is a separate species from Irritator, or if they are the same dinosaur.2 1
