CRETACEOUS CRYPTODIRE FOSSIL PLATE
Stunningly defined Manchurochelys liaoxiensis ancient turtle
Very rare 130 Million year old specimen
Manchurochelys liaoxiensis, also known as Ordosemys liaoxiensis, is described as a cryptodire (a turtle order) with a very low domed shell. It is an extinct genus of turtle in the order Paracryptodira.
It existed during the early Cretaceous of what is now northeast China. The species was discovered in the Jianshangou Bed of West Liaoning's Yixian Formation.
The carapace or outer shell had an oval outline, with the length being slightly longer than the width. Manchurochelys liaoxiensis looked like a modern turtle, but it was a primitive turtle and could not draw its head or legs into its shell. It likely fed on plants, small fish, and insects present in its environment. Manchurochelys liaoxiensis is most closely related to today's snapping turtle.
The Liaoning region, 130 million years ago, was an area crossed by streams and rivers and dotted with fresh water lakes and active volcanoes. The land areas were covered by forests of conifers, similar to today's pine and fir, ginkgoes and ferns. There were very few angiosperms or flowering plants. Marshy areas surrounded the lakes. Based on the plants represented in the fossil record of the area, it suggests that the area around Liaoning was a semiarid environment with a warm but dry climate.
This a a very well defined and excellently preserved 100% natural and authentic fossil from the cretaceous period, approximately 130 million years old.
It was most likely formed in the sedimentary layers of a lake or marshy area and the many fine layers can clearly be seen in the matrix.
Total size of plate - approximately 43cm x 37cm x 12mm thick
Size of fossil specimen - 27cm x 17cm
Turtle fossils are among the scarcest of small fossils and highly sought after by collectors. It is easy to see why. The plate makes a stunning display, whether in a comprehensive collection or as a centre piece on a wall.
It can really be described as a piece of art - Earth's ancient art - with a story to tell far superior to that of any modern artwork or artist.
