Fossil Friday! Today's FF video post is from Lake Texoma. We made our first ever trip to lake Texoma to search the duck creek formation for ammonites. After much research and planning, we arrived to find we could not access the locations we wanted, so we ended up scouting around. It turned out well and we found some great fossils including ammonites, oysters, clams and echinoids.

Yesterday, my son and I finally made a day-trip to Lake Texoma for some fossil hunting. We've been wanting to make this trip for while, but it can be difficult between both our jobs and weather, and lake levels. I planned for this trip by searching the google maps for good looking locations with a nearby shore access. Unfortunately, one spot turned into a private drive, and the other was closed off by the Corps of Engineers for some unknown reason. We didnt want to hit the same spot that everyone else goes to so we began just driving and looking. The first place we stopped was a gravel bar in creek. When I drove over the bridge and saw the bar, I immediately made a u-turn. I'm sure that this has been searched, but it didnt disappoint. There were a lot of Gryphaea in the marl walls as well as gravel. We found a couple large segments of ammonites and eventually found a small, complete ammonite, about 2 inches in diameter. Then we drove around the lake roads until we found a likely looking shoreline, which fortunately was only a short walk to the exposure. Hunting started slow, and we could see a couple piles of rejects left by other hunters. But we stayed optimistic and kept searching in depth, and then the finds started to show up. There were huge Gryphaea everywhere, many were 1-1/2" long. I eventually got tired of picking them up. There were huge oysters, but they were mostly broken. I did find a smaller one, about 4 inches across. Then there were many partial ammonites and finally several complete ones. Our favorite finds were the echinoids! I found the first one, and then my son found 3 more, all close together. Some of the ammonites are still imbedded in matrix, and I'm hopeful they will prep out cleanly. One of the small partials I have started trying to prep is having problems. Some of it come out clean, but some spot dont seem to have any separation plane between matrix and fossil (which is a steinkern anyway).

Found this a few days ago in a local creek that has Woodbine. When I picked this up it had an "echinoid sheen" to it. Also thought it was just a possible bi valve. Not so sure after looking at Turtle egg fossil or rather possible turtle egg fossils on Google.

The last weekend of September, I decided to visit some of my central Texas sites. I had been looking for a tetragamma for some time - the first one I found was collected illegally, totally by mistake, on federal property. And it was far from a perfect specimen. Well, after a few years of being teased by broken tetragamma bits, I found this beauty. I believe this is a tetragamma streeuwitizi - collected from comanche peak limestone. Please forgive the situ pic, motion picture was activated, and the sun was too bright to tell that it was a poor quality image until later. Initially thought was a phymosoma sp., until I got home and realized it was a tetra - totally stoked!!! Pic #3 also shows that my tetra retained one of her (yes, I just humanized my urchin) spines!!! This is a first for me. Thanks to @Uncle Siphuncle for cluing me into the rarity of tetragamma a few years back.

Hello, I picked this fossil up on Jebel Hafeet, Al Ain, UAE (United Arab Emirates). I think it's from the Cretaceous, however, I am not so sure. It is unfortunately very worn and eroded, but it is still the only one I have of its kind. The fossil itself it filled with small numulites. I saw a picture the other day of a conoclypus echinoid, and it looked quite similar to what I have. I figured you guys would be able to confirm whether it is or not. I also drew a picture of what I imagine it would look like whole.

Hi, I was hoping that someone would be able to tell me if the smaller echinoid is a juvenile Corystus dysasteroides or possibly another species. Both specimens were collected from the Jan Juc marl, late oligocene (Janjukian), Victoria, Australia. Thanks. (I posted this in the wrong place earlier)

This is an undescribed, new species of Tylocidaris found in the Lower Cretaceous Georgetown Formation of Williamson County, Texas. Discovered on April 12, 2009 by John Jackson.

Hi guys, I lost the label on this, I’m fairly sure it’s from the Pliocene of safi, morocco but I could be wrong, would anyone have any idea what it is? Thanks

There is a spot in the Peace, not far upstream of the Canoe Outpost, that yields relatively large quantities of the sand dollar shown in the photo below. I have these 2 relatively good examples and 3 more partials stuck together in a block. All are of nearly identical size. I had assumed Miocene based on the source, but the the publication from UF on "Pliocene and Pleistocene Echinoids" has the only sand dollars coming close. The closest matching in shape is Encope michelini, but the sample is twice the size of my examples. Anyone have experience with these?

Hi Guys, I don’t know if we have any echinoid experts on the forum but I figured I’d try, I’ll start with this piece this is miocene from the Murray river, australia, there is a lovenia woodi on there but I’m not sure what species the regular echinoid is, thanks for your help

I found it on a south west cliff/beach and it has a odd internal spine like thing. Any ideas? I’m quite bad at IDs as well, so any clues about it ? Please help. Here’s some photos hope this helps. Thanks for your time. God fossils still fry my brain, just thinking how old, and it’s trip to get into my hand still makes me go woah! Last 2 phots show the spine like thing quite well

The other day I acquired a few fossils from fellow members of the rockhound club who spend their Winters (except this past winter) down in Arizona and collect there and in neighboring states. They gave me the location via the Gem Trails book they used to find it, but of course that doesn't provide any info on the formation nor any specific IDs for what you find there. I'm having trouble (as usual) finding this information, so I wonder if anyone here has this info handy. I found a geo map of Calif and it appears to be Pliocene in that area, but it doesn't give any formation names. The area is in the Coyote Mountains, SW of the Salton Sea, north of Ocotillo. Looks like you drive north out of Ocotillo to get to the site. Anyone know the formation name or recognize the taxa I have here? Just two items, a basic bivalve (3 views) and a sand dollar-type echinoid (2 views).

Hi Guys, My son's friend asked me to id this and I'm embarrassed to say that I'm stumped! It's siliceous, it was found in UK and its owner has suggested it could be from Whitby (or less likely from North Cornwall or the Isle of Man). It's intriguing me because if you look through the little holes you can see daylight suggesting to me that the specimen might be fossil and not just a strange depositional feature. I'm convincing myself that I can see five-fold symmetry and that it looks like some sort of echinoid but I might be way off the mark. If you think it's depositional or diagenetic can you explain to me how you think it might have formed? Thanks for your time. Top view. There are holes or pairs of holes running down both sides and you can see daylight if you look through! Side view showing horizontal holes running through the specimen. Inside of the holes appears to be crystalline silica or some grains of silica. View of the other side, showing similar holes which go straight through Bottom view

My mother recently moved into a home in Shepherdstown, WV and when I mentioned I'd gotten into fossils recently she said the previous homeowner had left some fossils in the basement and that I could have them if I wanted. These have absolutely no provenance, I assume they're not from the area, but I think they're neat and I was just wondering if they were complete/distinctive enough to be identified. Also, is there anything I should do to clean them gently and keep them preserved? I have no experience with this type of fossil. There are 2 sea urchins and 2 shells, the larger sea urchin is about 4 inches across, the smaller is about 3 inches. he larger shell is about 3 inches, the smaller is 1.5 inches.
