Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg

These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

Have been under the radar a bit here on the forum, but plan to get more involved. Talk about involved!...the specimen featured here has been sitting in my shop for a number of years. As I prepared numerous Waldron specimens from my huge stock of unprepared material, I kept thinking and planning the preparation of this piece. This specimen was collected from the Middle Silurian Waldron Shale Shelby County, Indiana. The crinoid was found on the floor of a bench of Waldron Shale with only the very top of the crown exposed. So, the crinoid was in situ. From what was exposed I could see that

Earlier I posted a specimen that was sent to me from the Upper Peninsula of Michigan that turned out to be a non-calcareous alga from a Middle Silurian Lagerstätte: Late this summer I travelled to the site to search for more. After about a half hour of searching and splitting rock, I discovered that the algae and other fossils were concentrated in huge nodules. I collected some tonnage to bring back to "dissect" with a 3 lb sledge and a tile saw. Here's most of what I brought back: Here's most of what remained as "keepers" after much splitting and c

Is this a fragment of Encrinurus pygidium? Location / formation in tags. Scale in mm. @piranha
-
I think this one is a conodont (see tags for formation, location). Scale in mm. No conodonts were reported by Ehlers (1973) thorough study on these formations, so I am guessing if this is a conodont, it's a somewhat rare find.

I think this is a stromatoporoid but would like additional opinions before I label it. It comes from dolomitized middle Silurian limestone of northern Michigan. I thought it might be coral that had undergone diagenesis, but there are well-preserved Favosites present, so I'm pretty sure it's Stromatoporoid. They were abundant, as were the corals. Here's one in the matrix: Here's my specimen (cut with saw): Here's a "thin" section and an acetate peel:

Hello, everybody! I have been sorting through my wenlock limestone material, Middle Silurian and have a couple of personal problematica. I am wondering if any of you brilliant folks could help me out. Here is an object which seems to be an epibiont on a Favosites coral. 5 mm long and about 1.5 mm diameter at the widest. Is it a cornulitid ? Or a single corallite of Aulopora? Something else, maybe? And another one? On a solitary rugose coral. 3 mm x 1 mm. And an example of Aulopora from Wiki to compare : And a cornulitid that looks
