Unique double -number tail determines its relatives as well

In a recent study, a research team headed by Martin Ebert from Lud Wig Macsamilian University and Adrena Lopez-Riebello, from Unudad Education Lilo, examined the fossil fish samples of family category fishermans located at various museums.

Catorides are a medium -sized, fast swimming hunter fish of medium sizes (10-40 cm), which is known to have distributed their largest geographical distribution in Jurassic, at which time 14 leading species have been lived. They eventually disappeared in the lower Cretesis, where only three species are known.

In their study Swiss Journal of PaulovonologyEbert and Lopez-Rebilo’s purpose is to study the shape and rating of category.

He was eventually able to determine that 33 of the analysis of the analysis were from a new generation of categories, which was deposited in the upper Jurassic Platinic Basins on the Solar Hofin island in Bavaria, Germany, and from Germany’s Baden-Artberg’s Nofiplenniklinclek.

New species are called the Catoros Encopicodles SP. November, which combines the Greek word for Nuch εγκοπή (Enchoscopy í) and the word caudalis in terms of its caudal art, the features that are significantly unique in new species.

At first glance, the category encompostalis SP. Now is different from other caturidae, which has a strange form of Codal FIN as well as a high number of scale rows.

The scales, unlike other cattle species, was large and with the central surface plateau, with a specific ‘double emergent’ shape. Two extraordinary signs produce a high -speed profile unlike the ordinary thorny tails of other category species.

The central surface plate usually consists of four, short and wide central rays in the same case.

David Bell Wood, a colleague of Ebert, has speculated, “I suspect it’s an evolutionary innovation that was not included in the time test.

“There are two tail defects, but I suspect that you are natural. I cannot see any great benefit. This will help reduce the proportion of the aspect and thus increase the force-but it will come at the expense of losing the enthusiastic benefits of the thorny caddle.

“I will either guess that) for the lineomorphic condition for the lineage, and the species had a new hunt/location that needed more bursting or B.).

The other specific features that distinguish the caturus Enkopicaudalis sp. At first glance, there are high number of NOV scale row from other species and thick singer scales that cover the back of the rays of the hole.

Generally, the category species is exhibited between 51 and 56 scale rows, which is counted from “shoulder” to the previous art. However, the Cautoresaupecodales SP. There are a total of 91-99 rows in November. These scales are relatively small and smooth with the edges of the waist straight and there is no understandable pattern on their surfaces.

It is likely that the large number of each row and scale rows may be attributed to their smaller sizes. In addition, it is the sole category with the unorganized gland scales from the upper Jurassic.

Many other features of this are category features, including a very thin and stick -like Maxla (upper jaw), which is specific to caturades. It had 33 small teeth, while the teeth (lower jaws) had 25, two were three times taller than the microbes. This makes his teeth usually greater and wider than other categories.

Its glowler plate (a venical bony plate between teeth in some ancient fish), however, is one of the wider categories.

This discovery increases the most notable diversity that was shown by the Kachrs species during the Jurassic. Further research will potentially identify many new fish species, including categories, which help us understand us about early marine life.
