Fish tracks show the initial adaptation to move to the ground

The Poland’s Geological Institute National Research Institute reported a lower Daveen (419 to 393 million years ago) located in Holi Cross Mountain, Poland. Their analysis shows that the oldest record of examining the migration skills of the fish, the prediction of the first evidence of the first 10 million years is the first evidence of tetrapid locomotion.

Later, the prediction of the land attack is needed, more permanent stay, possibly encouraged by accessing new areas of feeding during low maize. Very few locations in Poland have previously recorded signs of LOC locomotions to make the land colonial from the first, mainly from Europe and Australia, with the coming date from the lower middle Dunnan of the Holly Cross Mountain of Poland.

Similarly, several ages are found in Valentia Island, Ireland. Evidence suggests that tetrapedes were already capable of effective locomotions on the ground at the beginning of the East Dunnan, which shows that the beginning of quadropidalism should also be summoned in old forms.

In this study, “Dipanovan fish marks do document the early adaptation of the bakers to move to Earth,” appeared in Scientific ReportsResearchers analyzed newly excavated traces and 3D scans to translate locomotions and snot anchoring, which was attributed to Dipanwan fish.

Field teams worked in Lower Dunnan (Medium Eminee) Silicastic marginal marine reserves, near Onska near the Central Holi Cross Mountains, and in two parts of small, abandoned sand stones in Kopek, in two parts, in the lower dimensional marijuana. Here, sand stones made in a minor maritime environment that show numerous phenomena through the plants.

The Tuffite Core protected the trace bearing levels from biometbration, which recovered the “true substrate” bed aircraft, which records the duration of Sesame-water or Sesameh Air Interface and Staissus before the submission of the subsequent collection. An area of approximately 30 meters² In the ojjad and about 15 meters² In Coopak, several dozen documentary documentary trace fossils protects in Seto.

Methods include partially exposed sandstone bed surfaces, cleaning and washing, field photography, 3D scanning, silicone rubber casting, and the protection of the situation. Measurement and scans used 3D scanner Aoxcan Loop+ and were analyzed with Blender 2.6. The XYZ Resolution was also made with 50 mm with a hand -holding scanner Zuskrotmat -800H.

The features of the Snow Imprints feature includes a trapisydial sketch in the Dorsal View, a deep curved profile of the lower jaw in the background view, and a pair of mausoleums in the upper lip ventral margin, such as Dinurinchus or “Cherudipators”, such as Australia.

The interpretation does not exclude swimming because the characteristic of the Sinusadal pattern is absent. Observations document about 11 11 % of twisted marks, of which 97 % are curved on the left. 35 Left -turning marks are important in terms of dating data, and it can represent the early assumption of the hand skin between the left hand, with the potential priority of the left hand.

Researchers have concluded that one of the trackways was partially developed by the emerging Dipanwan fish, which includes traces of trunk, feathers, and snot anchoring in the body, which is used as auxiliary tools to adjust the movement. In another, the single or double pairs of furls record the fish resting on its wings in the sesame.

Evidence represents the oldest famous rash locomotions in the semi -terrain environment and shows the physical or contradictory abilities of the genuine sister group free from the real tetraped lineage.
