Collaborations

Caribbean Sloths
I have been blessed of late to work with a fine array of people regarding sloths being recovered from water filled caves in Hispaniola, and those specimens are providing us with an amazing new insight into these island sloths and a whole host of other animals as well. We are indebted to our divers associated with the Dominican Republic Speleological Society @ www.dr-ss.com.
Dr. Siobhan Cooke, Assistant Professor at Johns Hopkins University
Dr. Renato Rimoli, Curator at Museo del Hombre Dominicano, Santo Domingo.
Dr. Juan Almonte, Vertebrate Paleontologist at Museo Nacional de Historia Natural, Santo Domingo.
Dr. Alexis Mychajliw, recent PhD graduate.

Paleodiet/Microwear
Investigations into the dietary and eating habits of extinct and modern xenarthrans can be done in a number of ways. I've previously worked with Dr. Jeremy Green, Associate Professor at Kent State University-Tuscawaras, in microwear on sloths and we are shifting to also include armadillos. We have recently started working with Ryan Haupt, PhD Candidate at University of Wyoming, who is using radioisotopic analyses in conjunction with microwear to provide new resolution to these studies and questions. Ryan also runs an excellent podcast, Science...Sort of, that covers a wide range of topics in a fun and educational manner; I have also been a guest on two episodes.

Reconstruction of Musculature
Many researchers work in this area but my collaborations have been with Dr. Virginia Naples, Professor at Northern Illinois University. We utilize accounts from the literature and our own dissections of modern xenarthrans to determine the position and extent of muscles in the extinct taxa. Specifically we have done this for the muscles of the crania related to feeding and chewing, but are working our way down the body.
I am also happy to know and hopefully work with Dr. Michael Butcher, Assistant Professor at Youngstown State University. He and his lab are doing amazing work in mapping the musculature and exploring the physiological abilities of those muscles in all living xenarthrans.
