This ancient
reptile trackway, about 315 million years old, is the oldest known
reptile fossil in North America. It was found in south-central
Kentucky. A tail-drag can be seen between the small footprints.
This fossil is a natural sandstone cast of the footprint, so the
footprints and taildrag stand out from the rock. See third story
below.

- 330-million-year-old amphibian skeleton found in western Kentucky
Spring and Summer, 1995: Geologists from the Kentucky, Indiana,
and Illinois State geological surveys, working on a project in
western Kentucky, found several large blocks of sandstone containing
skeletal material. Further examination indicated that the fossil
was an embolomere amphibian from late Chesterian (Mississippian
Age) strata. The Kentucky Geological Survey is coordinating research
on the specimen which has been transferred temporarily to a vertebrate
paleontologist who will be preparing the fossil for the next 1.5
years. Upon completion of preparation and initial examination,
a press conference will be held at the Kentucky Geological Survey
at the University of Kentucky. The specimen may eventually be
housed in the Kentucky Museum of Natural History.
- 313-million-year-old insect fossil found in eastern Kentucky
November, 1993: A scientific paper was published on the first
insect fossil found in Kentucky. The insect wing,, belonging to
a spilapterid (Palaeodictyoptera: extinct) insect, was found near
Manchester, Kentucky. The wing showed traces of original color
patterns. Sheltoweeptera redbirdi, the new genus and species,
will be part of the Kentucky Museum of Natural History collection.

1993, v. 11, p. 641-647.
- Oldest known North American reptile fossil found in south-central
Kentucky
January, 1994: The Journal of Paleontology published a paper on
a fossil trackway made by a small reptile approximately 320 million
years ago, making this the oldest-known reptile fossil in North
America. The trackway was found on a sandstone block in McCreary
County, Kentucky by Mr. Roy Hines. The trackway, referred to ichnotaxa
(trace fossil taxa) Notalacerta missouriensis, showed a
straight tail drag mark and hindfoot (pes) and forefoot (manus)
impressions made when the animal walked across a small muddy deposit.
The specimen is currently shown at the Geosciences Department
at the University of Kentucky, but will probably be housed at
the Kentucky Museum of Natural History, when built. Reprints of
the Journal of Paleontology article are available at Kentucky

- World-famous fossil coral site in Kentucky opens to public
January, 1994: The Falls-of-the-Ohio Interpretive Center, part
of the Indiana Department of Natural Resources, has opened across
the Ohio River from Louisville, Kentucky. The historically famous
Falls-of-the-Ohio is an outcrop of Devonian-age (375-380 million
years ago) coral-bearing limestone that occurs in the Ohio River;
the outcrop actually is within the Commonwealth of Kentucky and
is protected as a National Conservation Area. However, access
is best on the Indiana side of the river. The Interpretive Center
offers a museum, bathrooms, parking, picnic tables, and easy access
to the Devonian outcrops; guides are available. Call 812-280-9970
for more information about the Interpretive Center. The illustrated
booklet,"Fossil beds of the Falls of the Ohio" (Special
Publication 19) is available through the Kentucky Geological Survey,
606-257-5500.
- Giant gypsum crystal excavated in Jessamine Co. and put on
display at the Kentucky Geological Survey
Winter, 1995: The Kentucky Geological Survey acquired from the
Lexington Quarry Co. limestone mine in Jessamine County, Kentucky
a more than 2,000-lb boulder of giant gypsum crystals. Also found
on the boulder are crystals of barite, fluorite, and sphalerite.
The specimen was transported to the Kentucky Geological Survey
and is now on exhibit in the lobby of the Mining and Mineral Resources
Building on the corner of Rose and Clifton Streets, University
of Kentucky, in Lexington.
- Scientists examine Pleistocene (Ice-Age) animal fossils from
Big Bone Lick, Kentucky
Winter, 1995: Two scientists from the University of Kentucky examined
mammal fossils collected at Big Bone Lick, Kentucky, but now held
at the University of Nebraska. The fossils were collected on Commonwealth
of Kentucky property by scientists from the University of Nebraska
in the 1960's. Original correspondence between Kentucky and Nebraska
officials stated that part of the collection would be returned
to Kentucky after studies had been completed. Kentucky is now
seeking return of the specimens so that they can be placed in
a museum in Kentucky.
Big Bone Lick was one of the first paleontological sites in North
America; specimens were collected there by Major Charles LeMoyne
de Longueuil in 1739 and Thomas Jefferson authorized a dig there
by Captain William Clark, of Lewis and Clark fame, in 1807. Specimens
collected by them now reside in the Musee d'Histoire Naturelle
de France, the American Philosophical Society in Philadelphia,
and at Monticello, Jefferson's home.
