Dinosaur State Park, Friends

Dinosaur State Park, Friends See real, 200 million year old dinosaur tracks preserved in place! Enjoy the park and nature trails! The outdoor park and trails remain open.

PLEASE NOTE: The Exhibit Center is closed from March 1, 2022 through August 1, 2022 for the replacement of the HVAC system. In August of 1966, bulldozer operator Edward McCarthy was excavating a rocky site for a state building. He turned over a slab of gray sandstone and saw something very exciting: six large, three-toed footprints. Within a few weeks of the discovery, state officials decided to p

reserve the site as a state park. Two seasons of careful excavation resulted in one of the largest on-site displays of dinosaur tracks in the world. Fossil tracks are named independently from fossil animals. No skeletal remains were found at the Rocky Hill site so scientists speculate that the animal was similar to Dilophosaurus based on the shape and size of the footprints and the age of the sandstone where they are found. Come learn all about it during a track talk! The Park offers school field trips for grades 1 and up during the school year. As well as family-oriented programming on weekends, school vacations, and during the summer months. The anniversary celebration will include a “First 50” giveaway one Saturday a month for the first 50 families that pay admission on that day. The dates will be posted by the end of 2015. The giveaways will not be posted until the day of the events but will include a different item each month. Books, videos, posters, and dinosaur toys are examples of some of the items that will be given away. The park will have several days where admission will be free over the summer months. These dates will be posted after the New Year and will include Connecticut Open House Day in June and Dinosaur State Park Day in August. Lectures, animal programs, book signings, and other special programs sponsored by our Friends group will take place throughout the year. You will want to visit over and over again!

There's 3 months until Dinosaur State Park Day, where you can celebrate the 60th anniversary of the discovery of our trackway with us!

Fun Fact: Did you know that in 1978 the current exhibit center was built over the trackway, meaning the tracks are in the same place they were made 200 million years ago!

Dinosaur State Park Day is on Saturday, August 1st from 10:00 a.m. to 3:00 p.m.
We'll see you there!

🎉Happy Birthday Edward Hitchcock!🎉
Hitchcock was a geologist, Amherst College professor, and the first American Scientist to study fossil tracks. Through his research he created the science of studying trace fossils, known as "Ichnology". Hitchcock did much of his research in the Central Valley, where our fossil tracks are located!

⛏️But... What is a trace fossil?
Trace fossils are geological records of the biological activity and behavior of past lifeforms. This includes things like nests, burrows, and the footprints you see at Dinosaur State Park!

🦖You can learn more about Edward Hitchcock, trace fossils, and the Central Valley by visiting the exhibit center Dinosaur State Park.

Happy World Turtle Day! 🐢
You can visit Waldo the African Spurred Tortoise among our other turtally awesome shelled species at Dinosaur State Park in the exhibit center today!

🔍What's the difference between Turtles and Tortoises?
Turtles are mostly aquatic omnivores with a flatter shaped shell and webbed feet or flippers. They tend to have a shorter lifespan from anywhere between 5-60+ years. Tortoises are land dwelling herbivores with a more dome shaped shell and elephant-like feet. Tortoises have a much longer lifespan of anywhere between 25-100+ years.

It's Fossil Friday, can you dig it?
Pictured below is a Eurypterid, or "sea scorpion", an extinct group of arthropods related to horseshoe crabs, scorpions, and ticks that lived from the Ordivician period to the end Permian mass extinction (about 460 to 250 million years ago). Eurypterids are were among the largest aquatic predators during the Paleozoic and likely ate anything that crossed their path. They are considered the largest arthropods, but ranged in size from only a few centimeters to up to more than 8 feet in length! These sea scorpions lived all over the world in shallow seas and are commonly identified by their front appendages, known as chelicerae.

Did you know the largest and most diverse collection of Eurypterid fossils can be found at the Yale Peabody Museum right here in Connecticut!

It's Fossil Friday, can you dig it?
Pictured below are ammonites, an extinct cephalopod fossil that lived from the early Devonian to the Cretaceous period (about 400 to 66 million years ago). Ammonites are born with shells that develop new chambers as they grow. They would move their body into each new chamber and block off the old chamber with a wall called septa. Ammonites lived all over the world in shallow seas and had a diet consisting of crustaceans, bivalves, and fish. Ammonites ranged greatly in size from just a few inches to multiple feet in diameter.

There's 3 months until Dinosaur State Park Day, where you can celebrate the 60th anniversary of the discovery of our trackway with us!

Fun Fact: Did you know that although some of the original 1,800 tracks had to be reburied for protection in 1976, 753 tracks are still visible from our trackway in the exhibit center!

Dinosaur State Park Day is on Saturday, August 1st from 10:00 a.m. to 3:00 p.m.

It's Fossil Friday, can you dig it?
Pictured below is Semionotus, an extinct ray-finned fish fossil that lived from the late Triassic to the early Jurassic (about 247 -125 million years ago). These fish can be up to about one foot long and are considered ancestors to present day gars. The Semionotus has been found worldwide, but is most popularly found in freshwater lake deposits in eastern North America. You can see examples of Semionotus today at Dinosaur State Park!

There's under 4 months until Dinosaur State Park Day, and you can celebrate the 60th anniversary of the discovery of our trackway with us!

Fun Fact: Did you know the first footprints were discovered in Rocky Hill by bulldozer operator Edward Mccarthy while excavating for a project with the Connecticut Department of Transportation? The image in the second slide depicts Edward with one of the footprints on August 23, 1966.

Dinosaur State Park Day is on Saturday, August 1st from 10:00 a.m. to 3:00 p.m.

It's Fossil Friday, can you dig it? Pictured below is a Trilobite!
Trilobites are extinct marine arthropods that lived from the early Cambrian period to the end Permian mass extinction (521- 251 million years ago). Trilobites can range in size from only a few millimeters to over 2 feet long! There are over 20,000 described species of Trilobites as of today.
