Originally, the site was part of a stone
quarry owned by the
Kidde company called Roseland Quarry. In 1968, there was a discovery of dinosaur tracks on the quarry. With the news, a 14-year-old,
Paul E. Olsen who lived in Livingston, and his friend Tony Lessa started visiting the quarry to study them. Over a period of a few years, they uncovered more than one thousand dinosaur, animal and insect tracks from the
Late Triassic and
Early Jurassic period. When the fate of the quarry site became uncertain, the two teenagers came up with a plan to prevent the site from being developed. They made a
cast from a footprint of
Eubrontes giganteus and sent that to President
Richard Nixon to get support. Currently, the site is now part of the
Riker Hill Complex along with
Riker Hill Art Park and Becker Park. For many years, the public was allowed to collect fossils at the site, but now access to the site is restricted. ==References==
