izinto ezimnandi

Iinyani ezimnandi

1

Protohadros is the oldest definite hadrosaurid, or duck-billed dinosaur, known to science.2

2

Its name means 'first hadrosaur' because it lived so early in hadrosaur evolution.1

3

This dinosaur had a downward-pointing muzzle, which scientists think helped it eat plants close to the ground.2

4

Protohadros had a mix of primitive and advanced skull features, showing a step in the evolution of chewing ability.2

5

Its fossils were found in the Woodbine Formation of Texas, which was a delta environment during the Cretaceous.2

6

The only known species is Protohadros byrdi, named after the person who discovered it.1

Ukufunyanwa
Protohadros was named by paleontologist J. J. Head in 1998, based on a partial skull and some bones from the Woodbine Formation in Texas.42
Kusaxoxwa ngayo
Scientists debate whether hadrosaurs first evolved in North America or Asia, and Protohadros is a key piece of that puzzle.2
