Petalodus Tooth on limestone microscopic view

When I found my 4th Petalodus Tooth, I thought it was the 3rd. However it turns out that I did indeed find another one that I did not document. This one appears to be half a tooth. It sits on a large piece of limestone, that I may eventually cutRead More →

Amphiscapha

The fossil Amphiscapha appears readily within shale locally. Buried at an angle different from the plane the shale sheared from, this specimen is a bit unique. Only the raised rim was visible initially. Using precision tweezers, I utilized the sharp metal ends and a microscope to slowly reveal the restRead More →

It is a fossil something, but I am not sure what it is. I’ve stumped the few people I have shown so far. It has the familiar look of Calamites, but does not have the nodes. It was also embedded within limestone, which I do not find any plant fossilsRead More →

Petalodus Tooth from Pennsylvania

A fourth Petalodus Tooth has been found in the same general area I found the first three teeth. This tooth looks deep like the 2nd tooth. The two sides are missing and fractured, likely from splitting the rock. The tooth was dark in color when I found it and turnedRead More →

Pyrite on fossil

This is a simple photo view of some pyrite on a local carboniferous limestone fossil. There is only a little bit of it exposed in this specimen, but it’s flat and you can see the metallic glow quite easily at first glance. I’m not sure what sort of shelled creatureRead More →

While appearing to be a cephalopod, Bellerophon is a snail. It has existed since the Silurian and disappeared shortly after the great Permian Extinction. I’m not positive this is Bellerophon, but the growth lines visible resemble the genus. More about Bellerophon Online Article on WikipedaRead More →

Bornite

Bornite, also known as Peacock ore, is a mineral that tarnishes to different colors, ranging from blue, yellow and purple. This is the first sample of it I have found locally, right in my local shale pile. I have a feeling that I will be finding more of it nowRead More →

Pseudorthoceras side view embedded in limestone

First described by G. H. Girty in 1912 as found in Oklahoma. This specimen was 3/4 exposed as attached to a rock. I am not positive, but I believe it would break into more than one piece if I attempted to remove it. I am always finding either Pseudorthoceras orRead More →

Aragonite Shell Material

The very definition of a fossil includes objects that have been replaced by another material. These are called casts. Impressions are also fossils, such as the shape of a prehistoric fern leaf embedded in shale rock or the impression of a shell in limestone. Somewhat common in Western Pennsylvanian fossilsRead More →

Metacoceras Fossil from Parks Township, Pennsylvania

First named by Alpheus Hyatt in 1883, Metacoceras is one of the two most common cephalopods I find in Parks Township. Pseudorthoceras is the other one, a narrow straight shelled genus. This specimen shows nice banding where the individual chambers are on the shell. The first photo shows the shellRead More →
