Posts treating: "pelecypod fossil"
Tuesday, 17 February 2015
Once a hard shelled animal dies it's shell often lies around on top of the muddy bottom until it gets buried. While it is exposed it provides a hard surface for many other encrusting animals that otherwise would not be able to establish themselves. Today I have two examples of trace fossils that were left on the interior surfaces of pelecypod shells from the Devonian aged Panther Mountain formation in NY.First up is this shell which may be an Actinodesma erectum or another species. It's hard to [...]
The fossil appears to be Granocardium stantoni? pelecypod fossil. It existed during the Cretaceous Period (about 70 million years ago). This fossil was found in McNairy County, Tennessee (Ripley Formation).
Fossils from this locality have an identification PDF at this LINK.

Here is a picture of a pelecypod fossil housed in a display case at the Geologia building located on the campus of Sapienza University of Rome. The case can be found on the second floor of the building. The fossil is called Pecten jacobaeus and lived during the Pliocene Period. The fossil was found in Roman countryside.
The university was founded in 1303 by Pope Boniface VIII. In 1870,
Every so often I visit a local retired geology professor to chat about fossils. He has a unique fireplace in his study that was mortared together with various fossils. Here are few pictures of some of the fossil embedded in the fireplace. All the images were taken with a Motorola Moto X smartphone.I think the first image might be a model of a charophyte or some sort of Astylospongia fossil. Next is some sort of model of a foraminifera.The next two images are of colonial coral fossils.Last is [...]
This picture shows what appears to be a Homilodonta filistriata clam or pelecypod fossil. It was found in the Kope Formation (Eden Group) of Carroll County, Kentucky, USA. It dates to the Ordovician Period. According to the fossilworks web site, it is also known as Ctenodonta filistriata and Deceptrix filistriata.It is still in matrix and appears to have both
This fossil appears to be a Pterinea brisa Hall (or Ambonychia (Pterinea) striaecostata McChesney 1869) pelecypod fossil found in the Silurian Waldron Shale of Clark County, Indiana. Learn more about it at my earlier blog posting from June 20,
This image shows what appears to be a Pterinea brisa? pelecypod fossil. It was found in the Silurian age Waldron Shale layer of Clark County, Indiana, USA. It has not bee prepped yet but has very distinctive lines outlining its growth pattern during the creatures short life.Identification is based off of images from illustrations from Plate 28 (Figures 7-9) Indiana Department of Geology and Natural History Eleventh Annual Report John Collett State Geologist 1881. First [...]
This fossil imprint was a nice find. It appears to be a Pterinea brisa Hall (or Ambonychia (Pterinea) striaecostata McChesney 1869) pelecypod fossil found in the Silurian Waldron Shale of Clark County, Indiana. A similar bivalve is found in the Rochester Shale of New York called Cornellites emacerata Conrad.The Pterinea brisa was described by James Hall in the 1881 Indiana Geological Survey (pages 316-317; Plate 27 Figures 24-25; Plate 28 Figures 7-9):Body of shell (left valve) obliquely [...]
