ROCKY HILL, Conn. (AP) — Connecticut officials are pushing to promote a state park that is home to dinosaur tracks dating back 200 million years.

Dinosaur State Park in Rocky Hill is putting on several free events Saturday at the site, where a construction worker uncovered the tracks in sandstone while excavating for a state office building project46 years ago.

The project was immediately halted after the discovery on Aug. 23, 1966. About 2,000 dinosaur tracks were eventually uncovered and some 1,500 others remain buried for preservation.

Researchers say they came from a dinosaur resembling a Dilophosaurus (dy-LOF'-o-SAWR'-us), a three-toed carnivore that was about 6 feet tall and 20 feet long.

More than 50,000 people visit Dinosaur State Park and its museum each year. Saturday's anniversary celebration events run from 10 a.m. to 3 p.m.
