According to a paleotologist that was at U-Dig when I was there this Trilo's damage was caused by a predator (with grasping appendages similar to the Tulley Monster). The guys at U-dig said this was only the 3rd one they have verified to have predation damage. You can tell by the disruption pattern that it is not hammer or chisel damage. Anyway I think it's unique and tells a story. It's my favorite find of the trip.

yes it is. and it is quite uncommon, but many more than 3 have been found. here is one that i found on my first trip at udig. notice teh ends of the pluerae have started to heal and regenerate. yours is a particularly nice example. anomolicaris is the predator. parts of them are rarely found in the Marjum formation and i think one was found in the Weeks fm as well.

Very nice specimen showing the results of predation. Your specimen looks like it got away from whatever took a bite out of it (most likely an Anomalocarid). The bite mark resembles those commonly found on trilobites from the Burgess Shale which are attributed to Anomalocaris.

Pretty cool, John (and others). I've not seen this before. Something to keep on the lookout for.
