New Albany Shale Conodonts
Here are two freshly found conodont fossils in the New Albany Shale (Late Devonian Period). The first appears to be some sort of Spathognathodus sp. (Branson and Mehl, 1941). The second appears to be of the genus Elictognathus (Cooper, 1939). Both were found on a shale plate about 4 cm by 4 cm. Field of view for images was about 1 mm. Specimens were collected in Floyd County, Indiana, USA. Indiana Geological Survey Bulletin 41, Conodonts from the Jacob Chapel Bed (Mississippian) of the New Albany Shale in Southern Indiana by Carl B. Rexford (1969) was used for the identification of these fossils.

Platyceras dumosum Snail Fossil (ex-museum specimen)
This fossil is a Platyceras dumosum (Conrad, 1840) spiny snail (gastropod). It was found at the Falls of the Ohio in Clark County, Indiana USA. Fossils cannot be collected at the Falls any more but this one came from a de-accessioned museum collection in Michigan. The layer it was found is called the Jeffersonville Limestone which dates to the Middle Devonian Period. Judging from by the color this fossil might have been collected over 100 years ago.
The genus Platyceras was named by Timothy Abbott Conrad (1803-1877) in Third Annual Report on the Palaeontological Department of the Survey. New York Geological Survey, Annual Report 4(1):199-207 1840.
Thanks to Dale for letting me take these pictures.

Amadeus Grabau's Eighteen Mile Creek Palaeontology Book
This week a book arrived call the Geology and Palaeontology of Eighteen Mile Creek and the Lake Shore Sections of Erie County, New York - A Hand-book for the Use of Students and Amateurs by Amadeus W. Grabau Fellow in Palaeontology, Harvard University; Late Instructor in Palaeontology in the Massachusetts Institute of Technology. Published by the Buffalo Society of Natural Sciences 1898-1899.
I was attracted to this book for a number of reasons: Amadeus Grabau (1870-1946) is a famous paleontologist, Elvira Wood (1865-1928) did a number of illustrations for this work, the book is signed to a well known naturalist William P. Alexander (1881-1956) in Buffalo, New York, and the Devonian fossils are very similar to the ones we find in Louisville, Kentucky.
It is inscribed: "To Prof. Wm P. Alexander Whose absence on this occasion we deplore. With the compliments Amadeus W. Grabau Aug 19 /33." William Alexander while born in New York, studied violin and cello at the Conservatory of Music in Leipzig, Germany. He attended the University of Leipzig. He returned to the United States and taught agriculture at Cornell University. He served as assistant to Professor Anna Botsford Comstock (1854-1930). In 1920 he became assistant curator of education at the Buffalo Museum of Science. In 1940, he retired from this position in 1940 after co-authoring seven books and numerous articles about nature. It is possible he crossed paths with someone I have written earlier in this blog Elizabeth Letson (1874-1919) who was one time director of the museum and noted malacologist and resident of Buffalo, New York.
