Tentaculites, Coral, And Bivalves

[lotsofpets]

Upper Ordovician tentaculites, ON Brookville lake, IN. I'm pretty sure this is good as it's going to get with these tiny guys. Name the species.

Silurian? coral, near Greenville, OH. Genus? Species? I've looked at the specimen unter a scope, so no, it's not bryozoa.

Upper Ordovician Drakes? formation. Exit ramp 123 off of I-64 East, KY. Genus? Species? I believe they are the same.

Box o'Brachiopods. I know what most of them are, DO you? (a quiz to test your knowledge)

You have some really nice stuff here.

Your first fossil site looks to be Tentaculites http://en.wikipedia.org/wiki/Tentaculite

I see them alot in the Ordovician.

The coral is unknown to me, the pictures are too blurry. It could be a http://www.kyanageo.org/fossils/silurian/coral/CCL68_Heliolites_subtubulatus.jpg or a favosite coral

nice platystrophias and hebertellas

Nice did you find the tentaculites on the beach?

[lotsofpets]

Yes, sort of. There are some nice "cuts" along the shoreline. If you go out in a boat, some of the areas are fairly fresh and aren't picked over. The coral honestly isn't blurry at all. That's just the way it looks. Maybe someone can play with the contrast some for me? What about the bivalves?

I think some of the fossils listed as Tentaculites might instead be Cornulites.

I usually find Cornulites attached to Platystrophia brachiopods of the Ordovician.

That is an amazing pelecypod you found. It has both valves and the shell pattern is intact. Most times, I only find an internal mold or just one valve. As to its name, ??? Here is a list of Ordovician species: http://strata.uga.edu/cincy/fauna/bivalvia/bivalvia.html

I'll have to look at the bivalve site in more depth. I played with the contrast on the coral a bit and took some more pictures.

A few other interesting corals from the same area.

If you ever want to get together and hunt sometime I would be honered. Just pm me Mike.

The one farthest left, the smooth pebble, looks like a glacial erratic, syringopora coral.

I looked up the area you found the pelecypod in the Kentucky Geological Survey database. It showed the following layers exposed near the exit: Sunset Member (Bull Fork Formation), Preacherville Member (Drake Formation), and in the higher areas exposures of the Silurian Drowning Creek Formation.

It looks like Kentucky Paleontological Society found a similar clam in that area but did not name it: http://www.uky.edu/OtherOrgs/KPS/images/clam1x.jpg

This page shows their trip report for Owingsville: http://www.uky.edu/OtherOrgs/KPS/pages/napoleon.html#owingsville

Next time I plan to collect in the Frankfort area, I will PM you.
