Meet Amanasaurus Nesbitti

Around 233 million years ago, during the warm and humid Carnian stage of the Late Triassic, Amanasaurus Nesbitti roamed the Earth. Picture a time when Brazil was part of the supercontinent Pangea, surrounded by lush vegetation and diverse ecosystems.

This little dinosauriform, a member of the Silesauridae family, had some unique features. Standing at just 1.2 to 1.4 meters long, it was a compact herbivore with a triangular skull and small, peg-like teeth adapted for munching on plants.

The Puzzle of Amanasaurus Nesbitti’s Body

Amanasaurus Nesbitti was no slouch when it came to movement. Its long neck and legs suggested it likely walked on all fours, adding to its agility. Robust hind limbs and tail hinted at a strong hind limb-driven locomotion, perfect for dodging predators and navigating the Triassic terrain.

The discovery of Amanasaurus Nesbitti gives us a peek into the Late Triassic’s ecological dynamics. Imagine it sharing space with other dinosauriforms like Sacisaurus agudoensis and Gamatavus antiquus in southern Brazil. It paints a picture of a diverse community of these ancient creatures.

Triassic Tango

Amanasaurus Nesbitti didn’t dance alone. Its presence, alongside herbivores and carnivorous reptiles, reveals the intricate food webs that existed in Triassic ecosystems. This discovery deepens our understanding of how early dinosaurs adapted and evolved from their archosaur ancestors.

This new find adds to the growing list of dinosaurs that once called Brazil home. Think of Saturnalia tupiniquim, a small early predator, or Staurikosaurus pricei, a formidable carnivore reigning as one of the top predators of its time. Brazil’s Triassic period was a hotbed of dinosaur diversity!

Why is this discovery a big deal? Amanasaurus Nesbitti expands our understanding of:

  • Dinosaur diversity in southern Brazil showcases the region’s importance in early dinosaur evolution.
  • The unique traits of Silesauridae dinosaurs, give us fresh insights into their anatomy.
  • The complex interactions within Triassic ecosystems, shed light on the relationships between herbivores, predators, and the food web.

Calling for More Triassic Adventures

The discovery of Amanasaurus Nesbitti is just the beginning. We urge further paleontological exploration in Brazil and beyond. Uncharted territories may reveal new species, uncover evolutionary secrets, and provide a more detailed picture of Triassic paleoecosystems.


Amanasaurus Nesbitti, our “rain lizard” friend, emerges from the depths of time to remind us of the wonders waiting to be discovered. As we continue our journey through the layers of Earth’s history, each revelation, like this herbivorous dinosaur, adds to the intricate tapestry of life’s diversity.


Q: What was Amanasaurus Nesbitti?

Amanasaurus Nesbitti, a diminutive herbivorous dinosaur, inhabited Brazil during the Late Triassic, approximately 233 million years ago. Belonging to the Silesauridae family, it shared close kinship with fellow early dinosaurs such as Sacisaurus and Gamatavus.

Q: What does the name Amanasaurus Nesbitti mean?

The name Amanasaurus Nesbitti comes from two parts:

  • Amanas: This comes from the Tupi word “amana,” which means “rain.” This is because the dinosaur was found in rocks that were formed during a rainy period in the Triassic.
  • Nesbitti: This is the name of the paleontologist who discovered the dinosaur, Dr. Sterling Nesbitt.

Q: What did Amanasaurus Nesbitti eat?

Amanasaurus Nesbitti was an herbivore, which means it ate plants. Its teeth were small and peg-like, which were well-suited for eating soft, leafy plants.

Q: Who discovered Amanasaurus Nesbitti?

Amanasaurus Nesbitti was discovered in 2023 by a team of paleontologists led by Dr. Rodrigo Müller of the Federal University of Santa Maria in Brazil.

Q: Where did Amanasaurus Nesbitti live?

Amanasaurus Nesbitti lived in what is now southern Brazil during the Late Triassic period. This area was part of a large continent called Pangea, which included most of the Earth’s landmasses at the time.
