I was reading a thread today and James identified a rock he was showing as syringapora. When we were hiking a mountain stream the other day we found this rock. I had no clue what it was only that when its wet and sitting on edge of the stream it stands out pretty good. We found other smaller specimens as well. Its funny though we have been hiking quite a couple of canyons and trails and this is the first time we have seen this coral.....it stands out when you see it.  ....one down, many to go! jamesp

I picked up a couple slabs that look much different. It's really cool, but a lot different.  |

Mine is a soft material, I can scratch it with my pocket knife. rockjunquie, wow that's a lot different coloration, nice one. I am not sure I could tumble a couple of the smaller ones. Might be too soft? Pretty cool, thanks for sharing! |

Most shallow water coral thrives best in clear warm water and draws energy/nutrients from the sun. Most deep water corals do not feed off of sunlight, just nutrients in the water. For instance the massive petrified coral layer in Florida and S Georgia is a shallow(0-20 feet) species. It formed and still can be found at 90-110 feet above sea level or lower where rivers have undermined it. Little tectonic activity has effected it as it is a much later aged reef. So don't waste your time hunting on land higher than that. It is has optical light grabbing hex structure and very similar to modern day reefs in the Caribbean. Well preserved and no doubt a very shallow water coral. Guessing that Syringapora is a deep water coral due to the wide spacing of the tubes. But not necessarily. ETA: Guessed wrong, it is a shallow water coral fossilsaustralia.com/syringopora-tabulate-coral/Massive shallow water reefs thrive at high radiation locations, close to the equator.:  A few light grabbing designs of very shallow coral, close to actual size from Florida. Similar to Indonesian coral used in lapidary:    Closer up of above:     Modern day coral is a complicated organism. A single species can take on a dozen forms dependent on varying habitat. Modern research has resorted to DNA testing to discriminate. Many fossil corals fall into identifiable categories. Questions arise that individual species evolve into sub-species. The more they research, the more confused they get LOL. |

If you want to get a coral lesson Ken will help you out. He is a coral master and bounced his knowledge off me on another forum. I have taken him fossil coral hunting in S. Georgia. He quickly solved all ID issues of the fossil corals in the area and only wanted to hunt native artifacts on the shelf above the river LOL. So I shared those hunting grounds with him. Ken is a coral photographer. Taking set position photos of reefs semi-annually to annually to observe growth over time. www.thefossilforum.com/index.php?/topic/44401-flga-silicified-coral-macro-photos/page-3 |

A single species can take on a dozen forms dependent on varying habitat. Just to clarify, modern day corals are hexacorals (all stony corals) and octocorals (blue corals, soft corals). Syringopora is an extinct tabulate coral found exclusively in rocks of Paleozoic Era age. Along with the rugose corals, the tabulates vanished from the geologic record, went belly-up, at the conclusion of the Permian Period some 251 million years ago. |

Yep. Syringoporas are goners. Well said inyo. |
