WE are interested in the origin and evolution of invertebrate animals as informed by exceptionally preserved fossils from Paleozoic deposits. Our research brings together specimen-based traditional paleontology and fieldwork, developmental biology of extant organisms, and state of the art imaging and analytical techniques to study the evolutionary history of euarthropods and their close relatives.

NOSOTROS estamos interesados ​​en el origen y evolución de los animales invertebrados con base en el estudio de fósiles excepcionalmente preservados provenientes de depósitos Paleozoicos. El grupo combina paleontología tradicional, trabajo de campo, biología del desarrollo, y técnicas de imagen y análisis de vanguardia para reconstruir la historia evolutiva de los euartrópodos y sus familiares cercanos.

3D head organization in early Cambrian euarthropods

June 25, 2020

Our latest contribution to the study of early Cambrian exceptionally preserved euarthropods from the Chengjiang biota is now available in Current Biology. We investigated the head organization of small juveniles (5 to 7mm long) of the great appendage euarthropod Leanchoilia illecebrosa through microCT. Our results show the head organization of Leanchoilia in unprecedented detail...

Work remotely to prevent spread of COVID-19

March 18, 2020

In line with the safety recommendations implemented by Harvard University and the Faculty of Arts and Sciences, all members of the Invertebrate Paleobiology and Evolution Lab are required to work remotely until further notice in order to minimize the risk of contagion by the COVID-19 virus.

Please consult Harvard's webpage, including daily updates on the situation within the university and worldwide at https://www.harvard.edu/coronavirus

New OEB/EPS course on exceptional preservation and invertebrate evolution

January 17, 2020

We are super excited about our new course offering for Spring 2020, OEB/EPS 150 Exceptional Paleobiological Insights into Animal Evolution. We will learn about the the nature and biases of the fossil record, the mechanisms behind exceptional preservation in biotas ranging from the Precambrian to mid-Phanerozoic, and study some amazing fossils from the MCZ collections along the way! The course is open to both undergraduate and graduate students, and features a week-long trip to the Cambrian of Utah during the spring. You can find...
