This image on the right shows a tiny Devonian fish spine from our June trip to Red Hill, PA - any help identifying this would be much appreciated.
The long vertical fossil immediately to the right looks like the fossil of a minnow sized Devonian fish but [Herb] suggests it is actually a plant - archaeopteris - he has a keen eye! It is possible to peel back more rock covering the stem to verify but we're new to fossiling and this might be a bit tricky for us to attempt.
More photos from our Red Hill trip are included in the Members Gallery including Hynaria and Placoderm teeth, scales, and other fossils. The contrast of the green and red shale is striking. The greenish grey shale is pond or lake mud that dried up approximately 361 million years ago and the red is mostly fossilized soil. More of our Red Hill fossils are included in a posting in the Members Gallery.
