RARE LARGE PERMIAN AMPHIBIAN ON ROCK SLAB Boskovice Furrow, Czech Republic PERMIAN PERIOD: 290 million years ago NOTE: There are some unscrupulous dealers that sell the much less rare (and less valuable) variety of Discosauriscus as Letoverpeton! The appearance of the two is similar so a cursory visual comparison is inadequate. Letoverpeton was generally a larger creature than Discosauriscus. The skull of Letoverpeton is also broader in its profile when viewed from the top down compared to the more streamlined Discosauriscus. If you are unsure of determining the difference make sure you get a guarantee. In most cases, given specimens of the same quality, the Letoverpeton will be considerably higher priced reflecting their increased scarcity. Not to be confused with the more common Discosauriscus, this Letoverpeton is not only a rarer variety but this particular specimen exhibits some of the finest detail and preservation that you will ever find. This Letoverpeton moravicus species features full bone structures intact and plainly visible with superb articulation rarely, if ever found in these fossils. Even the most minute details of this creature have been wonderfully preserved in the original host rock. The skull on this example is remarkable - perfectly articulated in full preservation with exceptional suture detail. Often, black paint is applied to rock to recreate bone detail. This specimen has no such fabrication and bones have only been sealed in a clear, NON-PIGMENTED preservative to protect their fragile nature. ORIGINAL MATRIX SLAB IS UNBROKEN - NO REPAIR OR FABRICATION TO FOSSIL! An exquisite example of extreme rarity in this state of preservation. Highlighted gray area around fossil is a lower different color rock layer. It is where the overlying rock matrix layer was removed to reveal the amphibian skeleton. This gray region has been micro-blasted which resulted in a lighter and different hue. This amphibian fossil skeleton was NOT artificially placed in this matrix slab as some matrix fossils are, but is natural to and originally found on the slab you see in the photos. Letoverpeton was a prehistoric amphibian that is now extinct but once lived before the dinosaurs and are found in pre-adult and larval stages as fossils. They are a classified as seymouriamorphs, unique and primitive amphibians that lived from the Early to Middle Permian Period. Little is known about these creatures other than the fact that they were predators based upon the presence of sharp conical teeth. There have even been cases of fossils showing partially eaten seymouriamorphs in their stomach contents testifying to instances of cannibalism. This well-adapted land-dweller had wide jaws and walked on four short, sprawling legs. The Letoverpeton is more rare and found in much lesser numbers then the more common Discosauriscus amphibian of the same time and region.
