These basins are famous for the fossils of dinosaurs and other creatures that lived during the Jurassic and even during the older Triassic Period. For example, the Connecticut Valley is famous for its fossils of dinosaur tracks. Scientists say these basins were formed when what is now North America tore away from the supercontinent it had long been part of, stretching and cracking the earth's crust. However, the only Coastal Plain state that is really famous for producing dinosaur bones is New Jersey. Three other vertebrates are represented, Alabama and Mississippi adopting prehistoric whales and Georgia adopting the shark tooth.
Agatized coral is Florida's state stone.
One might also mention Alabama's state rock, marble. The only Coastal Plain adopted as a state fossil is petrified palmwood, which represents Louisiana and Texas.
