Morton made significant contributions to paleontology at a time when natural history research in the United States was still in its infancy. An active member and officer of the Academy of Natural Sciences of Philadelphia, Morton took good advantage of his access to the Academy s extensive collections, studying fossil specimens delivered to Philadelphia from overseas ports or the American frontier. "Morton cemented his reputation as a paleontologist after describing fossils unearthed in the digging of the Chesapeake and Delaware Canal. Later, he was selected to describe the fossils that Lewis and Clark brought back with them from the American West. Morton s studies of fossils in Cretaceous sand and marl layers in New Jersey showed their relation to chalk regions of Europe. A century later, such research would be used to document continental drift." (Penn Museum). Morton had some skill as an artist: His paper on new fossil species of Scaphites (ammonites) and Crepidula (slipper shells) is illustrated with an engraving made from his drawings.
