Dinosaur State Park
Rocky Hill, CTA 200-million-year-old fossil trackway, nature trails, arboretum, and interactive exhibits bring the Mesozoic era to life. Explore a paleontological museum and enjoy the outdoors...all in one trip in a park like no other. The Park features over 750 early Jurassic dinosaur footprints — one of the largest dinosaur track sites in North America — preserved in place viewable inside the museum, alongside exhibits about dinosaurs, fossils, Connecticut geology, and modern live animals.
Geologic History
The Park is located in the Central Valley which was created during the breakup of the super content Pangea around 220-170 million years ago. During the breakup several "rifts" or cracks were formed. The Central Valley is one of them and if it did not fail to continue to open, it may well have been the start of the future Atlantic Ocean. The Connecticut River flows through the Central Valley and portions of the Central Valley are referred to as the Connecticut River Valley.
For centuries the Central Valley has been known to contain outstanding specimens of preserved footprints uncovered in various locations including in the 19th century brownstone quarries. These tracks have found their way into museums throughout the world. In 1966, a new chapter was added to that storied history with the discovery of more than 2,600 individual dinosaur footprints, most classified as Eubrontes Giganteus. The term Eubrontes Giganteus refers to the classification of the tracks themselves. Scientists are still not completely sure which dinosaur made these tracks. Possibly a dinosaur that resembles Dilophosaurus.
Park History
During the excavation for a State of Connecticut Department of Transportation (CTDOT) laboratory in 1966, several tracks were unearthed by bulldozer operator by the name of Ed McCarthy on August 23, 1966. He quickly told the site foreman. During the next several days, paleontologists from Yale, Wesleyan, UConn, and Willimantic College (now Eastern Connecticut State University) visited the site. Over the next several weeks and months over 2,600 dinosaur tracks were discovered. On September 13, 1966, after consulting with officials, professors, and researchers, Governor of Connecticut John Dempsey declared the site of the discovery of the dinosaur tracks, a state park, Dinosaur State Park.

A committee was assembled by Governor John Dempsey to plan the future of the park. All agreed that the park should serve as an educational center due to the impressive dinosaur tracks, close proximity to Interstate 91 and its central location.
In 1968, the state released plans for the Park designed by the Mortin S. Fine & Associates. The original plans were extensive. Unfortunately, due to limited state funding the plan could not be completed.

1968 Proposed Plans for Dinosaur State Park.
Also in 1968, the Park was established as a Registered National Natural Landmark by the United States Department of the Interior. In preparation for the exhibit center proposed in 1968, workers unearthed over 750 tracks to the west of the original tracksite. This was to allow the public to continue to observe the tracks while the proposed exhibit center was being built above the original tracksite. However, after several years of little progress on funding the proposed exhibit center, it was decided to re-bury the original tracksite to prevent further decay of the dinosaur tracks. Around the same time, the Bubble dome what was covering the secondary, west tracksite had failed each year. A more permanent structure started to be planned in 1976 and was completed in 1978. This new structure is the geodesic dome that currently covers the secondary western trackway. It is hoped that someday, the original east tracksite can be uncovered and a modern conservatory can be built over it.

Museums
Exhibit Center
Head to the geodesic dome for a bird’s-eye view of over 750 preserved dinosaur tracks that date back 200 million years to the early Jurassic period. This portion of the preserved Mesozoic floodplain includes just a fraction of the over 2,000 dinosaur tracks discovered in the 1960s—the other rest of the tracks were reburied for natural preservation. Along with the tracks, check out a model of a Dilophosaurus—a 18-20 foot predator and a possible source of the tracks, dioramas of Triassic and Jurassic environments, fossil collections, and hands-on interactive exhibits.

Field Trips
Exhibit Center Field Trips
Available September – June, the park offers guided programs throughout the school year for grades 1 and up. Your visit will begin with a presentation, followed by a guided tour of the trackway, and an activity with the following themes:
- Grades Prek-1 Fossil Discovery - How do we know dinosaurs existed? Join us as we travel to the past to discover all of the different clues left behind by the dinosaurs and what each can tell us about their lives. Together, we will investigate fossil bones, teeth, and other surprising clues that helped these creatures survive!
- Grades 2-5 Fun with Fossils - How do we know that ancient life, including Dinosaurs, existed? Travel back in the time to learn what Connecticut was like at the time of the dinosaurs and what we can learn about dinosaurs from their footprints and fossils. Students will examine a wide variety of fossils and dinosaur models to learn what made dinosaurs unique.
- Grades 6-8 Layers Through Time - Piece together the existence, extinction, and changes in life forms over 400 million years, from trilobites to mammoths, by digging through layers of “rock” to discover animals that lived in the American West. Use the fossil record to investigate environmental changes over time, gaining an understanding of the history of the area from the Devonian period to today.
- Grades 9-12 and College The Speed of Dinosaurs - While dinosaur bones can tell us what dinosaurs looked like, and how they died, dinosaur tracks can tell us what they did while they were alive! In this activity, we will get down onto the trackway (no shoes allowed, just socks!) and take dino measurements. Then, using these measurements, calculate the estimated speed of the individual dinosaurs as they walked across our trackway.

“Mine" for gems and fossils in the park’s outdoor mining sluice. To participate, purchase bags of mineral and gem or fossil mining rough from the bookstore (prices range from $7 to $25 a bag, or $75 for a bucket). We recommend one bag for up to three or four people. "Mining" each bag takes about 10 minutes and park staff and volunteer will be on hand to help you identify your new treasures. Mining bags are purchased at the Friends of Dinosaur Park & Arboretum's museum shop located inside the exhibit center.
Track Casting
Available May 1 - October 31, 9:00 a.m. to 3:30 p.m.
Cast your own dinosaur footprint using real dinosaur prints — a one-of-a-kind experience and souvenir! The activity is free, but you’ll need to bring your own materials.
Materials – For each cast, you will need:
- 10 pounds of Plaster-of-Paris (no substitutions)
- 1/4 cup cooking oil
- Five-gallon plastic bucket
- Cloth rags and paper towels
- (The park provides Eubrontes tracks, metal rings, and water.)
Instructions – The entire process takes about 30 to 45 minutes.
- Clear off the Eubrontes Track and metal ring with broom and rags. DO NOT USE WATER.
- Oil the track and ring with your hands.
- Center ring on the track and wrap rags around the outside of the ring.
- Measure three (3) quarts of water (3/4 of one gallon jug); pour into the bucket.
- Add the ten pounds of Plaster-of-Paris to the water.
- Stir the plaster mixture quickly with your hands until it is smooth and has the consistency of cake batter.
- Immediately pour the mixture into the prepared ring.
- When the cast is hard, carefully remove the rags and the ring. Then remove the cast from the rock.
Know Before You Go – only one cast per family or group so all visitors have a chance to participate. We do not recommend casting during inclement weather.
