"The work of a lifetime lies within the hills surrounding the valley...Fortunate will he be who in this region devotes himself to the task of learning nature's secrets." C. N. Gould. Thus was the pronouncement of Gould in an article published in the Transactions of the Kansas Academy of Science in 1898 about the area of the Red Hills in southeast Kiowa County. Yes, well over a hundred years ago, paleontologists were well aware of and deeply entrenched in prospecting for fossils in the Red Hills. While the Niobrara Chalk of western Kansas is much better known for its rich and more famous fossils brought to the world stage by members of the Sternberg family, the older geologic layers in portions of the Red Hills yield great paleontological bounty.
A hundred million years ago, this area of the central Great Plains was covered by the Western Interior Sea. Areas which show the dark Kiowa shale at the lower portion of these Cretaceous age deposits were part of the relatively shallow part of this ocean. Thus, the layers of rocks and shale are rich in invertebrate fossils indicative of shallower waters. This testimony is presented by many clam, snail and oyster species found encased or loose in various formations. However, occasionally some vertebrates such as turtles, alligators, sharks and plesiosaurs show up. Plant and insect impressions have also been noted for the region. (During intermediate times when dry land existed between oceans.) While this rich natural history is ancient, it is significant enough to garner a spot among the Red Hills top eight natural wonders. Some of the amazing fascinations of this land of enchantment are revealed in subtle ways, hidden in the rocks and sediments from eons of time gone by to be discovered by current day naturalists.
Plesiosaurs similar to this depiction roamed the Western Interior Sea throughout the Cretaceous Period of the Mesozoic. They are among a number of reptilian sea monsters of the day. |
Dr. Reese Barrick, Director of the Sternberg Museum, Hays, Kansas along with Mike Everhart, Adjunct Paleontologist and Curator for the Sternberg Museum, poke around the Kiowa Shale of the Red Hills. |
Ammonites are extinct mollusks which were very prominent in the Mesozoic seas. See the picture below but think modern day Nautilus. |
Similar to our modern day Nautilus, ammonites were varied and very numerous in ancient times. |
Typically, only impressions of the ammonite shells are found either embedded in rock or sometimes unassociated. |
Occasionally, fish fossils such as the vertebrae in the upper part of this conglomerate are found. |
An occasional shark's tooth (see inset) can be found either loosely but also often embedded in a conglomerate of rock with fossil invertebrates. |
Oysters were common in the ancient sea of the Red Hills. This one is known as the "Devils Toe." |
Clams, also a bivalve similar to oysters, are found in the fossilized muds from the ancient sea. |
Really great blog. Lots of fossils in Kansas--not just from the Cretaceous Period, of course. See the web page "Late Pennsylvanian Fossils In Kansas" over at http://inyo2.coffeecup.com/kansasfossils/kansasfossils.html for many images of fossils and Kansas strats from the later Pennsylvanian Period--roughly 307 to 299 million years ago.
