Mastodont Buy-A-Bone


A creative fund raiser is underway by the Indiana State Museum that will provide funds for a Spring 2013 exhibition called Monsters of the Muck: Indiana's Elephant Graveyards.  The plan is to raise $125,000 of $200,000 needed to real-bone mount (with some casts for missing pieces) a bull mastodont found in 1998 in an ancient lake bed near Fort Wayne, Indiana.  It was radiocarbon dated to about 11,280 years old.  According to their web site, the creature was maybe 33 years old, about 3 meters high, and weighed approximately 2700 kg.

The remains recovered consisted of 292 bones and the fundraiser involves symbolically selling each bone for a certain price to help raise the needed money.  For example, the tusk casts would cost $5000 while the smaller foot bone casts would cost $50.  All donors receive a "Bone Ownership" certificate signed by the curator of paleobiology at the museum, a presentation box with an actual fragment of a mastodont tusk or bone, an acknowledgment of your donation at the exhibit, and the donation is tax deductible for American taxpayers.

Learn more about this neat project and how to donate on-line at this Indiana State Museum web page.

Images shown in this blog posting are of an American mastodont cast with other animal skeletons from the Ice Age.  The mastodont was excavated in August 2000 at the Gunz Farm near La Porte, Indiana by a group from the Indiana State Museum.

Agaricocrinus splendens

Happy New Year every one and I hope 2011 turns into a splendid year.  May the future bring increased understanding of the surrounding world and good health to all.

Today's fossil is the Agaricocrinus splendens crinoid.  It was found in Montgomery County, Indiana.  The creatures, whose fossilized remains are shown in the picture, lived in the Mississippian Period.

As of 2010, this fossil plate was on display in Washington, D.C. at the Smithsonian National Museum of Natural History.

Athyris spiriferoides Internal Impression

The Athyris spiriferoides brachiopod fossil found in the Jeffersonville or Beechwood Limestone of Clark County, Indiana. It is too bad part of the fossil is broken off.  The species was named by Eaton in the American Journal of Science and Arts, volume XXI. page 137, published 1831 (also referred to as Terebratula spiriferoides).  I have only found two of these fossils and this one is the first showing an internal mold.

The Smithsonian Department of Paleobiology Collections database lists three specimens in their collection: PAL 174179 (hypotype - Mahantango Formation - Hamiliton Group - Frame Shale Member - Bedford County, PA), PAL 177384 (hypotype - Romney Formation - Hamiliton Member - Alleghany County, MD), and PAL 177385 (hypotype - Romney Formation - Hamiliton Member - Alleghany County, MD).  

Dave at Views of the Mahantango gave me specimens of this species also. It was found in the Ludlowville Formation of the Hamilton Group of Erie County, New York (documented in this May 25, 2010 posting).

This link leads to the other Athyris spiriferoides I have found documented October 7, 2009.
