I was in Frankfort Ky. today, and had a little time to spare, so I stopped by an outcrop that I hadn’t visited since the winter. The outcrop is at the contact of the Millersburg/Tanglewood members of the Lexington Limestone, and was deposited in late Mohawkian/Chatfieldian time. The Millersburg was deposited above wave base, and the fossils are, generally, abraded(but not here). The Tanglewood was near shore and beach stuff. It is pretty small-as outcrops go around here-about 2m high and about 15m wide.
In a bed about a meter below the contact, numerous diplobathrid crinoids are found… some of which are intimately associated with odontopleurid trilobites.
I have mentioned the outcrop a couple of times before(like here and here). I found it on a fluke; I was trying to find another outcrop in which a friend had pulled a beautiful Gravicalymene, and I’m glad that I did! It has turned out to be one of the most productive “gardens” that I have ever come across. Though, I have only collected the talus, I have pulled over 100 Reteocrinus sp.(I quit counting) and two other genera of crinoid.
Recently, I have been pulling rare odontopleurid trilobites from the site. When I was younger(and had decent vision), I could spot a trilobite fragment from two meters. But now, I almost have to be on top of the thing to see it! I kind of wonder if the reason that I missed the trilobite fragments, at first, was because I had mentally blocked out everything but crinoids???
Well… apparently, those two plus the one in the link are all that I photographed.
And, the best for last.
Those should prep out nice!
All in all it was a good day to be near the “beach”.
