A Sea Monster Named Jim

Katherine Webbink, Information Systems Specialist, Information Technology

Olivier Rieppel and Jim Holstein tell the tale of the giant Lizard Eating Sovereign of the Sea (named Jim!). Touted as the "T. rex of the Sea," the Triassic sea monster was unearthed and brought back to The Field Museum where we hope to learn more about this new species. Research into this fascinating creature may teach us something about biodiversity crises and the recovery of ecosystems, both past and present.

In the Technology Department, Kate works on cataloging the Field Museum's digital media--how do we preserve the digital media bits of natural history? For now, the answer here seems to involve a lot of DNGs. Going forward, digital formats and the workflows that go with them change all the time, so collections need to stay on their toes if they don't want to lose data and the ideas that go with them.

BioBlitz at the St Joseph County Park District

Alan Resetar, Collections Manager III, Gantz Family Collections Center

On Saturday June 9th at Spicer Lake Nature Preserve County Park near South Bend in St. Joseph County Indiana, Dr. Gary Merrill (Adjunct Curator (Bryology) in the Department of Botany), James Louderman (Collection Assistant in the Division of Insects) and Alan Resetar (Collection Manager in the Division of Amphibians and Reptiles) participated in the fourth BioBlitz sponsored by the St Joseph County Park District.  A population of the declining cricket frog (Acris crepitans) as well as many interesting bryophytes and insects were found.  A short sound clip from the bioblitz with a calling cricket frog making its characteristic clicking can be heard here (I attached a sound file).  We did not want to disturb the frogs so there is no cute frog footage - only cattails and calls.

Fossils, Rocks, and Akiko

Inside the Field Museum there are several laboratories where scientists do their research projects. Visit the Paleontolgy lab where vertebrate fossil preparator Akiko Shinya works on fossils. You may also get to see a very good looking Psittacosaur!

The Fossil Amphibian and Reptile Collection includes over 7,000 catalogued specimens. The collections strengths include Early Permian fossils from Oklahoma and Texas, and growing collections of dinosaurs, and marine reptiles. A small but significant synapsid collection is included for historical reasons.

Earth Sciences at The Field Museum are focused on paleontology, systematics, evolutionary theory and meteoritics. Most of our paleontologists take an interdisciplinary approach in their research programs, combining fossil and living organisms together to extract information of broad evolutionary significance. Current research within the Robert A. Pritzker Center for Meteoritics and Polar Studies is on presolar grains to afford insights into our parent stars and the history of our Galaxy.
