Kane Posted March 25, 2018 Share Posted March 25, 2018 I've actually seen fairly thick worm burrows (not saying a worm did this one - could be crustaceans and other types of critters), but some of those are actually created by more than one worm, or with repeated entry by a single worm, thus expanding the burrow wall - an example of nature's conservation of energy, or just plain laziness. In terms of direction, burrows can go in just about any direction (think of a cross-section of an ant colony). Some traces can form fairly entangled and intricate burrow-mazes, such as Thalassinoides: 3 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Yeah that's possible! The matrix is about one and 1/2 feel thick, three and 1/2 feet wide, four feet long if the burrows showing are the top. The reason I assumed this was the top is because how limestone/ shale usually fractures Link to comment Share on other sites More sharing options...

abyssunder Posted March 25, 2018 Share Posted March 25, 2018 Thalassinoides will be my guess, also. They can be huge, sometimes. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
