We collected these fossils at the classic Devonian site at Red Hill in PA (where some of the first early tetrapods that crawled onto land were discovered). Shown are a Placoderm tooth, a very clear Hynaria tooth impression, Hynaria dorsal spines, Placoderm scale (note the texture on the scale) and a fragment that we aren't sure if it's skin or bone. Note the tiny white dorsal fine/spine from a Devonian fish. Most intriguing to us is the vertical fossil next to the white dorsal spine which looks like a full fossil of a minnow sized fish - I added a separate horizontal image of this and the horizontal has a piece removed to reveal a "lobe" at the left side. Since posting this it has been suggested that the long fossil is actually a plant - archaeopteris - and what we thought was a "tail" is actually a leaf. However, the white bony dorsal/spine fossil still appears to be a Devonian fish. This was our first fossil hunting trip but although we are new to the field, we are enthusiastic about our new avocation. Doug Rowe who co-discovered and manages the Red Hill site, was extremely patient and helpful. Cathy Young and Karenne Snow led the trip, which took us to half a dozen Devonian and Ordovician sites and introduced us to a wide variety of fossil rich terrains.
