The fossil represents a critical moment in evolutionary history, as it shows the common ancestor of dinosaurs, birds, and crocodiles. This discovery helps us understand the relationships between these groups and how they diverged over time.
The fossil was discovered in 2017 by paleontologists in Brazil.
The fossil was preserved in sedimentary rock, which helped protect it from erosion and allowed for its discovery millions of years later.
The fossil has a combination of bird-like and crocodile-like characteristics, such as a long neck and sharp teeth. It also has a unique hip structure that is found in both dinosaurs and crocodiles.
Studying this fossil can provide insights into the evolution of these three groups and how they adapted to different environments. It can also give us a better understanding of the biodiversity of prehistoric creatures and how they continue to influence life on Earth today.
