  1. The past two weeks I've been able to go out collecting a couple of times- two different locations, both Lower Devonian. Where I live the bedrock is all metamorphic. Nice scenery, wooded hills, lakes and wetlands, but metamorphic rock, so I have to drive over an hour to get to the nearest sedimentary exposures that are fossil bearing. My favorite locality that's within an hour and a half is Glenerie, which is located between Kingston and Saugerties just west of the Hudson River. It represents the type locality for the Glenerie Limestone. New York's Lower Devonian is divided into two groups: the Helderberg and the Tristates. The Tristates is the younger of the two and that's where the Glenerie Limestone is placed. I first visited the Glenerie site when I was a teenager. When I resumed fossil collecting 12 years ago, it was one of the first sites I revisited and quickly became a favorite (I lived much closer to it then.) For a while, I was there almost every week and this site was the first one I built up a collection from. As I became acquainted with other fossil sites, I visited Glenerie less often, but in recent years, inspired in part by my fossil hunting comrades, I've been going more. The Glenerie site is very rich in brachiopods which probably make up over 95% of the marine fauna. The vast majority of those are single valve. which display amazing detail in ornamentation, muscle scars, etc. Gastropods, tentaculites, bryozoans, and trilobites make up most of the rest of the fauna. Corals have been found by some of my friends on very rare occasions. I have found a single small nautiloid there as well as a partial crinoid calyx. I saw another this time, but unfortunately, was unable to extract it. The fossils are usually preserved in silica which resists the weathering that dssolves the limestone. Some of the limestone is densely packed with fossil shells. However, the rock is so hard that extracting the fossils which are actually softer than the matrix, is impossible. There are areas of the outcrop, near the top and in crevices where shells weather out complete and can often be obtained intact surface collecting. It was a good day for finding gastropods. I was able to collect a half dozen, including this one, a Platystoma ventricosa- actually two shells side by side, two and a quarter inch across.
