Jim Chandler replied to the topic Fossil in a conglomerate? in the forum What Is It? 2 years, 8 months ago
2 years, 8 months ago2 years, 8 months agoIf it’s a fossil it could be a coral. It could however be an igneous rock like pumice. Test the rock with some weak hydrochloric acid (also called Muratic acid dilute to 5 percent. If it fizzes it’s more likely to be a fossil.
Also check with a museum or school.

Jim Chandler replied to the topic Can anyone identify this? Thanks! in the forum What Is It? 3 years, 1 month ago
3 years, 1 month ago3 years, 1 month agoWhere did you find it? Mostly they are casts of some kind of Gastropoda (snail). But the location and something in the picture for scale ( a coin or ruler) will give more clues as to its identification.

Jim Chandler replied to the topic Dino tracks? in the forum What Is It? 3 years, 10 months ago
3 years, 10 months ago3 years, 10 months agoLooks promising. Look at a geological bedrock map of your area to see if your area has bedrock for the time of dinosaurs. Show it to a paleontologist in your area. Put a coin or ruler in your picture for scale.

Cool fossil! I am an amateur like you. I did some searching on the web and found an article about brachiopods with spines. Perhaps the author has the knowledge you are after. Also there are some references about identifying similar brachiopods you mentioned. Good luck hunting let me know what you find…[Read more]

6 years, 1 month ago6 years, 1 month agoPerhaps this is a calyx. Good eye to pick up this subtle detail. However it is too indistinct to be sure it is a calyx. Check out some images of better preserved calyx at:https://www.google.com/search?q=crinoid+calyx&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi43eLPlP7YAhXHg-AKHX30CVoQ_AUICigB&biw=1280&bih=630#imgrc=_

6 years, 3 months ago6 years, 3 months agoHi Gail, I have not collected any fossils in the West so I am not very familiar with fossils in that area. My best guess to get the discussion going is that it is a bone of some kind. (maybe a hoof, but I am very much guessing.) If I found a similar fossil in a marine sediment I might be tempted to call it a coral, but I think it may be a bo…[Read more]
