rwise Posted December 28, 2015 Share Posted December 28, 2015 Found this in a creek bed in the Cooke Co., TX area, Fort Worth Limestone and Weno formations. Need help with ID. Are these burrows or something else? Abundance of Mortoniceras, and several types of urchins in immediate area. There are burrows in the formations, but they look different. See below: Typical Burrows in area Thanks in advance for any assistance in identifying...... Thanks for your help in advance. Link to comment Share on other sites More sharing options...
