What was a Thespesius‘s habitat?

The Thespesius was usually found in terrestrial lands. Since they were herbivore dinosaurs, they needed to be around areas surrounded by plants and greenery.

Who did a Thespesius live with?

Thespesius reproduced by laying eggs, just like the other Hadrosaurs. They usually laid their eggs in wet lowlands.

Thespesius Fun Facts 

What did a Thespesius look like?

According to the fossils found, there is not much evidence that suggests how the Thespesius actually looked other than the fact that it was duck-billed and belonged to a genus named Hadrosaurid. The syntype fossils found by the paleontologist suggest that it is a caudal vertebra. The Thespesius was green-brown in color. Some dinosaurs had shorter front limbs, however, a rough image of the Thespesius suggests that it had longer front limbs and could walk and run on all fours.

How many bones did a Thespesius have?

There are not many records of the exact number of bones a Thespesius had, however, a study concluded that they have over 200 bones.

How did they communicate?

Some duck-billed dinosaurs produced low-frequency sounds from the elaborate crests and extensions on their breathing tracts.

How big was a Thespesius?

The Thespesius belonged to the genus Hadrosaurid dinosaurs and was around 23-26 ft (7-8 m) in length and about 9 ft (2.7m) in height. This was the average height of a Thespesius, however, a Hadrosaur's height could range from 10-65 ft (3-19.8 m). The Thespesius was one of the smallest in the Hadrosaurid species.

How fast could a Thespesius move?

A Thespesius usually had longer limbs on the front and back and if they ran on all fours, they could go up to 33 mph (53.1 kph).

How much did a Thespesius weigh?

The exact weight of a Thespesius is unknown, however, a Hadrosaur could weigh around 4409.3-8818.5 lb (2,000-4,000 kg).

What were the male and female names of the species?

There is not enough evidence that proves the difference between a male and female dinosaur, therefore the name of the male and female Thespesius is unknown.

What would you call a baby Thespesius?

There is no evidence that suggests there was a separate name for a baby Thespesius.

What did they eat?

The Thespesius usually ate plants and trees in the areas that they lived in. However, there are some reports that suggest that the Hadrosaurs also preyed on certain crustaceans (shrimp, crabs, and lobsters).

How aggressive were they?

There is no evidence that supports the aggressive behavior of a Thespesius.

Did You Know...

The fossils of the Thespesius were actually found by geologist Ferdinand Vandeveer Hayden in Philadephia from a surface of rock formation in Nebraska and the name was given by Joseph Leidy.

Since they were duck-billed, they did not have large and pointy teeth like other animals. They had hundreds of tiny packed teeth.
