Lower Devonian Trilobite These specimens from a chert bed in the Kalkberg Formation Hannacroix Member near Port Jervis, NY. This ~1” thick bed accumulated brachiopods and the occasional gastropod; parts of Paciphacops sp. are also present. Pictured specimens were recently collected by the neighbor's grandsons. The partial cephalon has a fairly well defined eye, which may permit distinguishing it as a P. hudsoniscus rather than P. Logani (see Trilobites of NY Fig.5.4). The cephalon is protruding from the bottom of the plate shown. Gordon (scale for cephalon blurred partial penny low rh )

A dime will cover the partial specimen. Chert bed near Port Jervis NY Thanks, Gordon

Driving west on Route 20 towards my favorite Middle Devonian Hamilton sites in Madison County I always pass this limestone road cut on the west side of Schoharie County just outside the tiny hamlet of Leesville, NY. It is an exposure of the Lower Devonian Kalkberg Formation, part of the Helderberg Group amd it's richly fossiliferous. I have collected from there in the past and there's a nice-sized Favosites (tabulate coral) that I've been trying to release from the wall for the past few years now. Each time I stop there I give it a few more whacks from my sledge, but so far it won't budge. This spring on yet another foray to Central NY, I was in no rush and decided to give that Favosites a few more whacks. Again, no luck, but I noticed a nice Machaeraria formosa (brachiopod) lying free from the matrix, a nice consolation prize. I decided to spend a few more minutes checking out the site to see what else had weathered free and did pick up a number of specimens. The next day, on my way home I stopped again and checked out the road cut on the other side of the highway and collected a few more things. In addition to what I picked up there were scores of crinoid stem discs scattered about, bryozoans, and of course brachiopods. Maybe some day I'll spend a bit more time there. A pair of Machaeraria Formosa, a Pentamerid brachiopod. My only previous one has just a single valve. Both of these have two. Not sure on the ID of this single valve specimen. I'm guessing Uncinulus campbellanus, a Rhynchonellid brachiopod.
