Sorry about the tag ambiguity but I’m at a loss. This was recovered from an old fossil collection sold retail in about 1955. Any ideas would be helpful. Family? Genus? species? US Penny (and cat hair) for scale. Thanks, Glenn

Hi Everyone! I should preface that this collection of photos were taken on multiple occasions to this location. I just wanted to share with you all typically, what my experience fossil hunting is like. This is not the only location or formation that I personally collect from, but it is the most frequent location I visit and is relatively accessible at all times of year. Anyway, essentially what we’ll be seeing here is the deposits of a 2ma old bay, represented by the Rio Dell Formation, then the Carlotta Formation, orange conglomeritic sandstones representing a delta that flowed into said bay, all uplifted by a faults driven by subduction. ON TO THE PICTURES!

Found on 1450 meters above sea level in the anti mount lebanon range (mid to northern part). Those mountains are the natural separation between syria and lebanon. a local cut on a 90 meters hill to extract construction stones exposed few fossils among the debris. Just cleaned it with water. looking very close, the agatization is cristal clear.

Hello everyone! A friend of mine was just given a group of fossils from a relative and has very little/no info on them. Through searching through this forum, we were able to I.D. most of the pieces, but this one we were unable to recognize and were hoping someone could help. There is no locality information associated with it unfortunately. Thank you everyone for your time/help, I really appreciate it!

A bunch of miscellaneous fossils for trade
Misha posted a topic in Member Fossil Trades Bulletin Board
Hello everyone, I have decided a while ago that I would focus on collecting Paleozoic material, because of this there are quite a few fossils I have that I purchased a long time ago and do not have an interest in keeping, these guys are not that special and I am not looking for much of anyone even does want to trade with me, but I do prefer Paleozoic material. I will post what I have here. 1.Lebanese shrimp fossil Cretaceous GONE/TRADED 2. Geocoma carinata I believe from the Solnhofen 3. Chunkosaurus 4.some cretaceous teeth, spinosaurus, Squalicorax, scapanorynchus, enchodus 5. Some gastropods 6.otodus obliquus Morocco eocene -

I am really trying to learn my common invertebrate fossils. Can someone, once again, confirm my tenative identification, or correct me? I really appreciate it. The fossil in question is this oval fossil. After doing some research my guess is it is a crinoid of some sort. I am guessing that the little "nipple" in the center of the oval is where the normal hole is, but why does it have a line disecting the oval into two distinct parts? If it is not a crinoid, can someone please tell me what I am looking at, and where I went wrong on my identification? Thanks, Doug

First point, I cannot get a decent image of this fossil to save my life. That being said, I took a bunch of sub par image in hopes someone can put the pieces together to come up with an id. It measures approximately 35x22mm and is definitely a different material than the host rock. I found it in the same area that I have been finding all of my other fossils. This is outside Willow Springs, Missouri, USA. I originally thought it might be a rugose coral of some sort, but it looks to have horizontal segments or something similar. I am about 95% (or more) positive that it is a fossil and not just geology. I will continue working on attempting to get better images. If I do, I will add them to the thread. Thank you for your assistance.

I posted a first hunting trip with my daughter and have a few I have no idea. These were collected out of the Stull Shale member, Upper Pennsylvanian. Layer is full of Neochonetes if this helps (as in I could have filled a 5 gallon bucket without moving more than a couple feet). For reference (I cant find my photo scales) everything is 2-3cm long. Thanks for looking. Just trying to help my daughter label them before she takes them to school to show off. Crinoid Head parts? Crinoid sac parts?

Hello from Kansas again. As I posted yesterday in the intro section, my 10yo daughter has stated an interest in fossil collecting. So, I took her out to known spot with a couple thick shale members in the lower part of the Virgilian Stage, so ~305million. We were actually searching the Stull Shale to be exact. Luckily, it had rained a decent amount a few days ago so we just examined the runoff spots. It was pretty run of the mill stuff as far as I can gather but she is really excited and wants to do more outings. I might just have created a monster... Although, there are worse things that she could bug me about. Anyway, on to her finds. I hope I have identified them correctly, feel free to correct me if I'm wrong; I do have a college degree but it has absolutely NOTHING to do with paleontology LOL. I will also post a couple that I am having problems with in the ID section. For reference, all specimens are 2-3cm in length. Crinoids Neochonetes Rhombopora Rugose coral - Most likely Lophophyllidium, or rare chance of a Caninia tip

Hi everyone, I found a rock that has multiple small gastropod fossils and gastropod impressions in it. When looking at it a little closer, I saw this grouping of three fossils. Two are gastropods, but I am unsure of the third. Is it also a gastropod that still has the host rock over it where it has not eroded or is it something different? The scale is in millimeters. This was found outside of Willow Springs, Missouri, USA and is a surface find in disturbed soil. Once again, thank you for taking the time to help a rookie learn. I appreciate it. Doug

Hey everyone, I am looking for any reccomended websites or databases that can help me identify several invertebrate specimens in my collection. Specimens range from ammonites, echinoderms, brachiopods, molluscs etc. I have locations where most were found or acquired, but I would like to get a species ID on them at least. Morphology tends to blur at times depending on the sample. Any references or ideas?
