Datos curiosos

1

Segisaurus had a wishbone, called a furcula, just like birds do. This was one of the first times such a bone was found in a non-bird dinosaur.2

2

Its bones were first thought to be solid, but a 2005 study showed they were actually hollow, like other theropods.2

3

The only known fossil was found by a Navajo man named Max Littlesalt in 1933, who was keeping livestock in the canyon.2

4

Segisaurus lived in an environment like modern sand dunes, and its fossil was buried in sandstone.2

5

It had a long tail and long forearms, and its legs were powerful and long compared to its body.2

6

Scientists think Segisaurus was closely related to Coelophysis, but it had some unusual features that made them question that at first.2
