I have a lot of unopened Mazon Creek concretions and though I do put some out in the winter for the Freeze / Thaw process, the vast majority, especially the larger ones do not open. So to dwindle my concretions, I have no problem whacking them with a hammer, and that is what I was doing today. As we all know, this is not the best way to do it since it can damage a nice specimen, but I take my chances. I always picked up any concretion that looked promising and never passed up larger ones. This all depends on the are that you are collecting, concretions from Pit 11 are never super

Here are two new Mazon Creek finds I'm not positive on. This first one looks very familiar but I can't place it. The second is a nice 3D piece of wood. My best guess is a Psaronius stem (tree fern), but I haven't found anything like this before so I was hoping for a second opinion. @Nimravis @stats @Mark Kmiecik @deutscheben @RCFossils I appreciate any help.

I'll update this thread with my Mazon Collection over the next few weeks. With some good weather out yesterday, I managed to get my first fossil hunt in for the season and will post a report in this topic. I will be moving this upcoming summer which will put me even further from Mazon Creek so I have purchased a few pieces to fill in the genus/species I haven't found yet and will mention if I purchased a fossil. I still hold out hope to find some of these pieces I purchased eventually but will realistically be difficult if I only can make 1 trip a year. Fauna Tullimo

@stats @Mark Kmiecik @RCFossils @Peat Burns @connorp @deutscheben@fiddlehead I had been in contact with a friend (Bob) of mine that I met over 30 years ago. I met him through my fossil mentor Walter. Bob and Walter would collect in the 70’s and 80’s with many well know collectors, including Francis Tully. The would also bring fossils to the Field Museum so Dr. Eugene Richardson and others, could ID some of their finds. In our talks over the last several months, he had spoke about selling his collection and I advised him that I would be interested. We came to an agree

I am thinking that this is an example of Palaeoxyris prendelli, if it is, I believe it is my first of this specific one. @RCFossils @stats

I've been spending a lot of time lately studying the Mazon Creek flora, and am continuously astonished by the diversity and quality of specimens that can be found. I don't think we see enough plants on the forum, so I figured I would go ahead and share some of my favorite finds. First is a specimen I recently shared, and a fitting start to the thread. This is Crenulopteris acadica, the most common true fern found in the Mazon Creek flora. It has been the most common plant I find, accounting for probably half my finds. Next is a favorite of mine. This is a s

Just came across this piece in a box of loose concretions. It has the look of an insect wing, but believe it might be a Neuropteris inflata leaf. What do you think? @RCFossils @deutscheben @stats @connorp @Mark Kmiecik Sorry for the darker pics, but this is a real black concretion.

I have two odd pieces tonight and was wondering if anyone has an idea. @RCFossils @deutscheben @Mark Kmiecik @stats @connorp This first one it odd looking, I am thinking fauna, but wonder if it is a seed. This next piece reminds me of an insect, but I think it might be a worm.

@RCFossils @Mark Kmiecik @connorp @deutscheben @stats Looking for thoughts on these few pieces- It looks a bit like the barnacle Illilepas damrowi Thinking possible Reticulomedusa greenei This next one is odd looking and the only thing that I can think of is an Octomedusa pieckorum. Lastly, looking for something on this bivalve.

Yesterday at work, I ran into a co-worker who knew that I collected fossils. He had me meet him at an area on his property in Coal City that was having some construction taking place and advised me that he thought concretions were there. I started looking around and found a number of them. Unfortunately, this area will covered over today. Below are a couple that I found in situ. I found this big concretions opened and face down. I rubbed it on my pants leg and thought it might be an Asterophylli
