Six years ago, an esk mosque dragon was discovered near Litomyle

The most interesting fossil remains of Mossur reptiles on our land were accidentally discovered in the village of Doln Ride near Litomyle. It comes mainly from the time when one group of these top predators was replaced by a species.

There used to be dragons on our land, but they were not the reptile reptiles spitting out of the mouth of a fire, but a large motto reptiles with fin-shaped limbs. There were even several of them. We wrote about plesiosaurs and pliosaurs, but a separate article will definitely send you the most important discovery of the quarry of another sea dragon from our land, ie mosasauroid.

Mosasaurids in general, or at the time of the last flowering dinosaur, are among the so-called clamping reptiles (d clamping, Latin Squamata), they are also not fully related dinosaurs. They were very adapted to life in the water, and in the moths of that time, the shakers stood on top of the food pyramid.

The best remnant of their existence in our country is a beautifully preserved fragment of the lower elite of the hitherto unknown Mosasaurid from the village of Doln jezd near Litomyle. It was discovered six years ago, in 1960. The official confirmation of this first confirmed discovery of the remains of a mosasaur was made in 1965.

It was well done during the excavation work at the house in the Lower Ride near Litomyle by Mr. Hurych, a fifteen-year-old cyclist there. It is an exceptionally well-preserved lower elite with eight cones and other pointed teeth. Even the quality of the find cannot be determined with certainty to which genus Mosasaurida belonged.


A fragment of the elist eskho tethysaurinnho mosasaurida, a predatory mosque beach, associated with the current serpent and monitor lizard, in the former exposition of the National Museum in Prague. A representative of the group from the Lower Ride covered areas of the daytime period in the late Turonian period, about 92 and 90 million years ago. It was probably the development of a primitive form of the name mosasaurida.

As stated by the paleontologist Vlastislav Zzvorka in 1965, it can be safely said that it belongs to a certain species of mosasauroid. In the periodical asopis Nrodnho Muzea (ada prodovdn, slo 134) mention Dr. Zzvorka nsledujc (abbreviated by the author): There are imprints of kdovch ml on the rocks, mainly of the kind GOLDF canalifera lime. It is extremely beautifully preserved. Exempl found it and F. Hurych, then a ride to ZD in Dolnm, passed to the National Museum in Prague. The fossil cannot be found precisely because it was discovered when stones were smashed during the demolition of the masonry of an old building in a field near the Lower Ride, with the local designation Pibyoves. The view of the masonry of the old building, it must be assumed that the building material was from the immediate vicinity. The whole area is a building with a copper shape. An example that was written in the book of the finger of the paleontological department under. 1063/60, is in chemical origin, in a rust developed in the Middle Turonian. They are especially regularly developed teeth

At the time the quoted text was written, mosasaui had been known for two centuries, so it was far from one of the first discoveries in this group. Of course, Mosasaurids are much better today and more in detail than six decades ago, when it comes to paleoecology, birth, physiology and other aspects. For example, we know that they were closely related to the current snakes and wars, that they could be warm-blooded, that they probably had forked tongues, and were often black in color.

Reconstruction of the form of a mosasaurida of the species Platecarpus tympaniticus, which

Reconstruction of the form of the mosasaurida species Platecarpus tympaniticus, which includes modern knowledge about the form of their propulsion machine, the tail. Apparently, these reptiles did not ripple in the water, but they had a firm marrow body, which moved the forward before, strong, flattening the tail.

And what exactly have we found out so far about the Czech representatives of this group from the Lower Cavalry? A fragment of the maxilla, ie the upper elite of the Whose Mosaic Reptile, was probably discovered in the sediments of the Jizera Formation in pusts with a high content of coccus, dating from about 92 and 90 million years ago (the so-called Middle and Late Turonian period). It was therefore probably a relatively archaic form of mosasaurida.

The elist is divided into two responses and one tooth was removed from it for further research. The elisti fragment is a total length of 18.15 centimeters and 3.5 centimeters high. The total length of this individual thus reached only a few meters, an accurate estimate of the boe in the preserved fossil material is not possible.

For the purpose of a detailed study, the fossil was examined by a potato tomograph in cooperation with the Czech Technical University in Prague. The shape, placement and profile of the dental crowns of the Czech mosasauroid correspond to the situation with mosasaurids from the subfamily Tethysaurinae, the scientists formally agreed on its existence in 2012. The Czech representative is particularly closely related to the second Hangoniasaurus inexpectatus from the countries of Hungary, Russellosaurus coheni ze Spojench stt a Tethysaurus nopcsai from Morocco.

By day

According to the current knowledge, there may be an inaccurate reconstruction of the shape of the mosasaur. In fact, the animals did not ripple when moving in the water, but they were moved mainly by a strong tail with a fin similar to, for example, a raccoon.

The current presence of this mosasauride and also its predecessor in the role of the top predators, the pliosauride, which became extinct at this time, is, by the way, one of the most interesting contributions of Czech paleontology to the issue of Mesozoic sea reptiles. Findings from our country document the development of early mosasaurides for a very long time, and thus also how they probably gradually replaced pliosaurides.

Just as in the case of the discovery of the Czech Long-necked and Mole-necked Plesiosaurs, in the case of the Mosasaurid from the Lower Cavalry, we will have to repent of the possible discoveries in order to learn more about them.
