There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Fossils tell the story of where these species used to live. These are fossil skulls of an American black bear, a raccoon, and a packrat from the Holocene of California, embedded in a block of original sediment. Credit: Alan Shabel.
