436 million -year -old Brechipads used Brussels to avoid crowds

Understanding how the ancient species has arranged themselves in space is an important puzzle in Pelvicology, but there is a direct evidence of how prehistoric organisms have used to manage their physical structure, it has long eliminated scientists. Now, researchers in China have previously revealed direct evidence: About 4346 million -year -old Brechipads from the initial Silorian era used to maintain a small, braastal -shaped structure called City, at a distance of the “checker board”.

Results, published in The action of the National Academy of SciencesThe Chinese Academy of Sciences came from a research team led by Professor Huang Bang and Professor Rong Jiao at the Nanjing Institute of Geology and Pilotology. Researchers studied the fossilized remnants of the Nuclear Clepta, which is a britchopid species, which is preserved in rocks from Tongzi and Ranhoi areas of Guizo Province.

Brichu Pods-once dominant over the dominant sea creatures once in the pelvic oceans-there is unusually well behind the well-protected fossils, not only their shells but also their delicate sets. These thin, elastic structures, which are found on the edge of the curtains of the britipid, are rarely found in the form of gems-especially in the aftermath of the aftermath of the Cambrons-their small size (about 20 micrometers in diameter, thinner than human hair).

To naked how the whistle survived for about 43 436 million years, the team used modern imaging tools: scanning electron microscopy (SEM), X-ray fluorosis (XRF), and Micro-C. They found that the whistle was preserved through a unique process: they were first -related to oxygen -free water through pyrite, then coated in the calle as the sea situation suffers from less acidity. This double protection saved them from both crushing and crushing, even later Pirates rusty in iron oxide.

With the confirmation of the whistle, the team turned to the wider population. Using local analysis tools – including nearby neighboring map -making and theson multi -court, they discovered that Brechipads were not collectively scattered. Instead, they created a unprofessional, a sample like a checker board, which suggests the active rules for interval between individuals.

Researchers found a clear mathematical relationship: The average distance between Breachiopads was 1.5 to 2 times the length of their sets. How did the stationary visible creatures achieve this? Unlike some britchipids, the nucleosopira clipta lacked the poles (or pedestrian) and had a smooth, disk-shaped shell-trolls that potentially allow them slowly slipping, either mm, either through the weak streams or their body.

When two people get closer, their extended whistle is gradually indicated by gradual adjustments over time. The result was a stable arrangement that minimized the competition for the Flutter feeders that needed space to pull food.

Researchers noted, “This is the first time we have linked a specific anathetic feature directly – this tiny whistle with a significant local sample in terms of statistics in fusses fossils.” This study provides extraordinary evidence that ancient communities were not only formed by opportunity or environmental forces, but also through biological reactions – organisms use to make their body a place.
