It has been a couple of years since we went last, but is it too late this year to head back out to Pit 11 area? We have always looked around Monster Lake. The finds are so so, but wondering if there is somewhere else we should try or just stick to that area. Thanks, Todd

So a friend told me that this was a Trigonotarbid. My Dad, the paleontologist, had it ID'd as an unidentified anthracomartid. Any thoughts?

Hello- My son and I recently found this Tully Monster. I am wondering what everyone's thoughts are on cleaning this, and what approach may be best? I have cleaned jellyfish and some other white calcified looking material from these types of concretions using vinegar for a few minute soak, but have heard that it may not be a good idea since it removes some of the material that helps define the imprint. The Tully we have was found in two different scenarios. The first image, the side was facing down in the dirt a the top of a hill. The second was found face up in a pile of leaves at the base of a hill. The side with the darker green black seems to be the one with the most potentials for cleaning but I am no expert so wanted to check to see if we are better off just leaving the sides as is. thanks in advance, -tom

Hello- I am posting for the first time on this site, it's been a great resource for comparing some concretions I've found over the past few years. I've been taking my son on these collecting adventures, and we seem to find at least one nice specimen per trip- although it sometimes take a few months for them to crack open! We found this concretion in Braidwood area, pit 11. It had already split but still together. I have some similar looking shrimp but not 100% sure what this is because the overall form looks a little different, so hoping to get some help here. Maybe it is a shrimp as well? thanks in advance for your help! -tom

I found this half nodule in the southern area of Pit 11 several years ago. I was told by someone at a fossil show it is likely a piece of seaweed. He described it as it being a wavy leaf similar in appearance to a lasagna noodle. Any information about it would be greatly appreciated. Thanks
