The Cretaceous in New York, US

Paleontology and geology

On Long Island, we find some Cretaceous sediments in the Coastal Plain region. The Coastal Plain consists of layers of sedimentary material, sloping gently towards the ocean. Many of the deposits are composed of materials that have not yet been cemented or compacted into rock. These deposits formed during the rise and fall of sea level, as sediment was eroded from higher land to the west and transported by rivers to the coast.
