I found what seems to be a fossil of Brain Coral attached to a shell.
jmz007 posted a topic in Fossil ID
I inherited a rock and mineral collection from my father, who bought them from a collector. We are in the process of identifying for fun. We found one that we are unsure if it is a fossil or not, and a Google image search for it brought us here. I am fairly certain that this was imported, but Oklahoma has been submerged several times (Brain Coral doesn't fit into those time frames though). Thanks.- 6 replies

I collected this piece in Brisbane, Australia. Can I pease ask: How do I know if it is fossilised coral or just recent coral? (how can I tell) Thanks. Can you please give me more information on this piece, what kind of brain coral is it ? Thank you so much!

This is probably an exercise in pareidolia - but could it be a brain endocast? This was self collected July 9, 2011 on San Juan island in Washington State. It was found on private property near the shoreline on the SW corner of the island. The local geology is a complex mixture of Orcas chert and formations of sedimentary and volcanic layers contorted together, peppered with glacial deposits. There are other fossils in the vicinity, including various plants and what I believe are devonian era fish fossils. At first, I thought this was a thunder-egg or nodule that turned to chert/agate. Then, it struck me that it looked like a brain. Perhaps a brain coral of some sort? But it doesn’t look like the photos of brain corals. It did look more like the stromatolite fossils, but no clear match. Something from my biology studies years ago noticed what looked like features of the mammalian brain. But brains don’t fossilize. It also looked too big to be a brain, especially a single lobe without a cerebellum. Was it part of a marine mammal brain? Some sort of brain endocast that turned to agate? It weighs 77g and has not been thoroughly cleaned. One of the photos included is 'as found' and the others show the fossil after it was rinsed off. I haven't given it a thorough cleaning to avoid harm to the sandstone-like coating. I’d love to hear what people think.

My father found these in his back yard near Lynchburg, VA. They were partially buried and covered with jus leaves on top. About 5 feet from one another. There might be more, he hasn't looked yet. They are both around 10 x 8. Pics 1 and 2 are the different corals, the last 4 pics are detailed images of the first coral. He took them to a local fossil hunter who confirmed they were fossils and is waiting to attend their local meeting. He used some solution to test if it was mineralized as one or another (?), expecting it to be the most common, buy it was not. Sorry to be so cryptic. Any help is appreciated.
