patrickirvin Posted October 20, 2019 Share Posted October 20, 2019 These two items were found in a gravel deposit in west central Alabama, US. The larger is a bit over 1 inch long and the smaller about 1/2 inch. Can anyone help me identify what they are? Link to comment Share on other sites More sharing options...
TqB Posted October 20, 2019 Share Posted October 20, 2019 Welcome to the forum! Both are corals, probably rugose, either solitary ("horn coral") or pieces of branched colonial ones, and they look silicified. I'm not sure it's possible to say much more as fossils in gravel deposits can be derived from a wide range of sources and ages. 1 Tarquin Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted October 20, 2019 Share Posted October 20, 2019 Hi, and welcome to the forum. Corals for sure as Tarquin said. If they are silicified, which appears to be the case, you can soak them in vinegar which will eat away the rock matrix but won't react with the silicate coral. It will expose more of the fossils and remove sediment that covers it. Be aware that this only works with minerals that don't react with acids. If the fossil reacts with the acid it will be damaged by the acid. Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

Notidanodon Posted October 21, 2019 Share Posted October 21, 2019 Probably solitary rugose corals they might look nice if you sliced them up but that’s just preference Link to comment Share on other sites More sharing options...
