About the author

Born in 1856, Jacob Lawson Wortman was an American physician and paleontologist whose career moved from medicine into fossil collecting and museum science. Reliable museum and library sources describe him as a medical doctor who joined important vertebrate fossil expeditions and built a reputation as a skilled field collector.

He worked with major figures and institutions of his time, including Edward Drinker Cope, the American Museum of Natural History, and later the Carnegie Museum of Pittsburgh. Sources also credit him with taking part in expeditions across the American West and with discoveries that helped shape museum collections and scientific understanding of extinct mammals and other fossil animals.

Wortman died in 1926. Today he is remembered less as a household name than as one of the hardworking experts behind many classic paleontological discoveries, and his published papers still reflect that practical, exploratory spirit.
