piranha Posted March 10, 2012 Share Posted March 10, 2012 Here are two fun fossils from the Pennsylvanian Breathitt Formation in eastern Kentucky. Upon first glance they look like possible Asteriacites sp., starfish resting traces. In fact, they are Asterosoma sp., deposit-feeding worm burrows. These star-shaped ichnofossils are a welcome addition for research and study. Enjoy the new 'stars' to my collection.

Auspex Posted March 10, 2012 Share Posted March 10, 2012 Those are nice, well defined examples; way to collect!

Auspex Posted March 10, 2012 Share Posted March 10, 2012 I am at very high risk of succumbing to ichno fever; it's all too cool...ahhhh, the collection one could amass! If I had the space, I'd be all over it!

squalicorax Posted March 10, 2012 Share Posted March 10, 2012 Reminds me of a type of feeding trace. Gathering around them from one spot. What is the matrix composed of?

piranha Posted March 10, 2012 Author Share Posted March 10, 2012 Reminds me of a type of feeding trace. Gathering around them from one spot. What is the matrix composed of? You are correct... 'deposit-feeding worm burrows' was a vague description. Thanks for clarifying that point. Reading through the paper indicates that Asterosoma occur in claystones, interbedded sandstone / shale facies and the most robust examples found abundantly in fine-grained sandstones. Although sedimentology is not my long suit, I'd have to go with the latter in this case. Link to comment Share on other sites More sharing options...
