Kate LoMedico Marriott is a graduate researcher in paleontology. She trained in sculpture at the State University of New York at Purchase, then earned an interdisciplinary B.A. at State University of New York at New Paltz, and a M.S. in Earth and Environmental Sciences at Brooklyn College in New York in 2021. She is the former in-house paleontologist at Astro Gallery of Gems on Fifth Avenue in New York City and the author or co-author of several publications on ammonites, including one systematizing the paleoart theory of heteromorph ammonites (now in press) and a new method for fractal analysis of ammonite sutures (in preparation). She has also submitted research in fossil mammals for publication in the near future. Kate was a Special Mention Finalist in the International Award on Scientific Illustration in Madrid, Spain for her work on heteromorphs. In 2020, Kate became the second paleoartist to be inducted into the Ocean Artists Society. She is also the co-founder of The Society of Invertebrate Paleoartists.
