What is the State Dinosaur of Connecticut?

Just South of Massachusetts, geographically, is Connecticut and along with the similar location is a similarity of state symbols, in this case especially the State Dinosaurs and Fossils of Connecticut and massachusetts. We take a look at what they are and why they are similar below.

Dilophosaurus was named as the State dinosaur of Connecticut in 2017, joining Eubrontes Giganteus, which are likely the footprints of a Dilophosaurus type dinosaur, as the prehistoric state symbols. both the Dilophosaurus and the fossilized footprints are dated to around 200 million years ago.

The dilophosaurus is certainly a iconic dinosaur, although its fame does stem from a lot of mis information from the Jurassic Park franchise. it was not particular small, and it is not known to either have a neck frill, or to have the ability to spit poison!.

We actually have a Dilophosaurus facts article here on the site. With a print out and other facts as well.

Why is Dilophosaurus the State Dinosaur of Connecticut?

Although significant of finds of Dilophosaurus have been found in Arizona ( see below) Arizona 1 – already has a state dinosaur, although it chose after Connecticut, and 2 – Tracks of what was either a dilophosaurus or a close relative have been discovered in Connecticut.

The Dinosaur tracks discovered in 1966 in Rocky hill are a three toed theropod dinosaur, and are called Eubrontes Giganteus. This is the name of the fossilized footprints rather than the name of the dinosaur however.

So in 2017 the bill signing into law the Dilophosaurus as the State Dinosaur for Connecticut was signed by the Governor Dannel Malloy was signed. As we mentioned they are thought to be from a dinosaur similar to a Dilophosaurus and connecticut is sticking with that story!

Where was Dilophosaurus discovered?

Dilophosaurus was a genus of theropod dinosaur that lived during the Early Jurassic period, about 193 million years ago. It was first discovered in the early 1940s by paleontologist Samuel Paul Welles in the Kayenta Formation of Arizona, United States.

The first specimen of Dilophosaurus was found in the Petrified Forest National Park in Arizona, and more fossils have been found in the Kayenta Formation and elsewhere in the western United States. A further two fossils were also found in the area after Welles was shown their location by the Native American people the Navajo.

Dilophosaurus was a relatively large theropod, with an estimated length of about 20 feet and a weight of around 1000 pounds. It is known for the two thin crests on its head, which were probably used for display or to make loud vocalizations.

What is the State Fossil of Connecticut?

The state fossil of Connecticut is, in a round about way, the same as the state dinosaur of connecticut. The State fossil is actually Eubrontes Giganteus, which is the scientific name of the dinosaur footprints found in Rocky Hill in 1966.

They are thought to be of either a coelophysis or a Dilophosaurus and were adopted as the state fossil of connecticut in 1991.

The Dinosaur footprints have been dated to around 200 million years ago, which would be of a similar age to dilophosaurus, and both Connecticut and Massachusetts have a wealth of these that are studied and researched.

you can check out the other state dinosaurs, those that have adopted one as a state symbol, here in the following list.

You can also read more about State dinosaurs in our US State dinosaur page as well linked here and below.


So while both the state dinosaur of connecticut, and the state fossil, may be the same animal, only one of them is currently a resident of connecticut. The fossilized dinosaur footprints are found in the state, and the likely owner of them was found elsewhere.

However an absence of proof does not equal a proof of absence and the footprints making up the State dinosaurs are very likely to belong to a dilophosaurus or relative. Which does indicate that 200 million years ago they were walking in what would later, much later, become Connecticut.
