butchb Posted December 28, 2019 Share Posted December 28, 2019 Hi guys, This is my first posting on the forum, constructive criticism is appreciated. Each year, when the water level in the lake is lowered in late fall, I go there in search of crinoids The first set of photos shows one of my better finds of 2017. This small slab (approximately 9 x 12 inches) had partially eroded from the shore. I was more than pleased to see all crinoids exposed along the weathered edge. Hopefully, there are some nice ones hidden in the center. Last year, while walking up a watershed near the lake, I found a slab of bedded limestone with the calyx pictured below. I decided to downsize the slab. The rock split along the bedding plane to reveal this: There were a couple of similar but smaller slabs nearby. I carried them back to the truck to split at home. I found one more nice calyx embedded in the rock. Pictured below are two more of last year's finds: While walking next to the waterline, I found the fragmented cephalopod pictured below. I was not sure if I wanted to keep it, so I set it aside to examine more closely on my way back. It was only after I looked at it again on my return that I noticed the tooth at the top. This year has not proven to be as fruitful as last year. The first photo pictures a calyx in somewhat rotten matrix. What should I use to stabilize it? One more Does anyone know the bryozoan to which the funnel shaped appendage pictured below belong? Thanks for looking 10 Link to comment Share on other sites More sharing options...
connorp Posted December 28, 2019 Share Posted December 28, 2019 Wow, those are some nice crinoids! Looking forward to seeing more of your finds. Link to comment Share on other sites More sharing options...
Wrangellian Posted December 28, 2019 Share Posted December 28, 2019 Nice stuff! I've got a few specimens from the Bangor Limestone but I'm afraid to venture any guesses with the IDs offhand.. Someone here should be able to tell you the names including that horn-shaped bryozoan, which is a nice specimen, by the way! (I believe that's the whole bryozoan, not a part of something larger). The main glues that are recommended are Paraloid or Acryloid (B72) or similar, which you buy as beads and dissolve in acetone. It is easily reversible with acetone too, which is an important feature. Sometimes crazy glue is OK as long as you're sure you're not going to want to undo it. It will come apart with acetone too but it's more troublesome. If I were you, I'd glue that one split calyx back together and then prepare from the outside (or get someone to do it for you)... and then please show the results here. 2 Link to comment Share on other sites More sharing options...

Jeffrey P Posted December 28, 2019 Share Posted December 28, 2019 Those are some excellent finds. That first slab looks particularly promising. If properly prepared no telling what you might find. What you can actually see is worthwhile enough. Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 28, 2019 Share Posted December 28, 2019 Welcome to the Forum. Those are potentially some awesome crinoids. Can't help with ID, but I would look into getting them prepped out. @crinoid1 @crinus Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

FossilDAWG Posted December 28, 2019 Share Posted December 28, 2019 @crinoid1, @crinus, or @Archimedes should be able to help with IDs. Crinus also has an excellent web site that includes images of his many crinoids from Alabama, which should be useful for you to ID your finds. You certainly found some very nice crinoids. The first slab in particular has potential to be spectacular, and may merit professional prepping if you don't have a lot of experience. I have found crinoids and blastoids around the Cedar Creek Reservoir, but nothing with the density of complete crinoids you have on that first slab.

grandpa Posted December 28, 2019 Share Posted December 28, 2019 Welcome to TFF from Austin, Tx. You certainly know how to make a grand entrance - beautiful specimens, esp. the large slab with multiple species. Looking forward to more of your posts.

FossilNerd Posted December 28, 2019 Share Posted December 28, 2019 Hello and welcome! A nice crinoid calyx is on the bucket list for me to find, and here you are with a boatload of them! Very nice ones at that! Looking forward to seeing more of your finds and I agree with the other opinions about getting them prepped. It would make them even more spectacular!

This small slab (approximately 9 x 12 inches) had partially eroded from the shore. I was more than pleased to see all crinoids exposed along the weathered edge. Hopefully, there are some nice ones hidden in the center. Nice slab that should prep out easily. Hard to tell what crinoids you have other than lower right may be a Cymbiocrinus. Last year, while walking up a watershed near the lake, I found a slab of bedded limestone with the calyx pictured below. I decided to downsize the slab. this is a Dasciocrinus. It looks like it is in the hard limestone and will be very difficult to prep even for the professional. I do not bother with these any more. You end up doing a lot of damage to the specimen just to get it in decent shape. The rock split along the bedding plane to reveal this: I think this is going to be a Phacelocrinus. It will be very nice once prepped. The pieces in the negative can be cut out and put back on and then prepped from the top. I would not glue the whole thing back together. this will also be a very nice specimen. There were a couple of similar but smaller slabs nearby. I carried them back to the truck to split at home. I found one more nice calyx embedded in the rock. Hard to tell what you have there. But it is going to be nice since most of it is buried. Pictured below are two more of last year's finds: Oklahomacrinus sp. Phanocrinus bellulus While walking next to the waterline, I found the fragmented cephalopod pictured below. I was not sure if I wanted to keep it, so I set it aside to examine more closely on my way back. It was only after I looked at it again on my return that I noticed the tooth at the top.

Shamalama Posted December 29, 2019 Share Posted December 29, 2019 Nice finds! The Mississippian epoch is full of nice Crinoids if you can find the right exposure. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.
