lcbergan Posted August 22, 2021 Share Posted August 22, 2021 I just returned from a dig near Baker, Montana. I found this part of an Edmontosaurus jaw with the teeth replaced by siderite. I thought it was a rare replacement. If important, the KT boundary was very visible on this ranch. The section is about 3 inches by 3 inches. 2 1 Link to comment Share on other sites More sharing options...
