Oldest animal fossil footprint on record discovered in China

Scientists think they have discovered the 550-million-year-old footprints of a small bug-like animal in the Yangtze Gorges area of China.

An global research team discovered the fossil tracks in China dating back to the Ediacaran Period, just before the Cambrian Explosion when life on Earth increased rapidly.

The study entitled "Late Ediacaran trackways produced by bilaterian animals with paired appendages" was published June 6 in the journal Science Advances.

The oldest footprints left by an animal have been recently uncovered in southern China.

President Trump weighs unnecessary pardon of Muhammad Ali
When the Supreme Court heard his case in 1971, all eight judges ruled in Ali's favor. Trump told reporters that he was thinking "very seriously" about pardoning him.

Bilaterians are one of the most common body types in the world, now and throughout history, but previous fossil evidence for them only goes back as far as the Cambrian.

However, this creature - which provides the earliest evidence of an animal with legs - would have existed around 10 million years before then.

While the researchers are unable to identify the animal behind the footprints, there are three types of living animals with paired appendages: arthropods such as bumble bees, annelids such as bristle worms, and tetrapods which include humans.

The scientists said that it appeared the ancient creature paused several times while it was crawling along the ancient mud, perhaps to feed off a mat of microbes or burrow to find oxygen.

The White House said Alice Johnson had been a model prisoner and worked hard to rehabilitate herself. The president commuted Ms Johnson's sentence as his seventh act of clemency.

"If an animal makes footprints, the footprints are depressions on the sediment surface, and the depressions are filled with sediments from the overlying layer", Shuhai Xiao told the Independent while speaking of the finding.

This places them perhaps even 10 million years before the "Cambrian Explosion" (roughly 541 million years ago), the moment in time which sparked the incredible evolution of life that led to the unbelievable diversity of species that we see today.

The researchers speculate that the same creature left both the tracks and the burrows, suggesting an animal that scurried and tunneled its way across the ground.

'Arthropods and annelids, or their ancestors, are possibilities. This movement tells them that the animal may have been hunting to obtain food. Other research has suggested that the evolutionary roots of bilaterians should go back further than that, but fossils had never turned up until now.

With an average of one attack a week this year alone, school shootings are now a reality students and teachers live with. Jesus, that's to the tune of the alphabet song, and Twinkle Twinkle . what a horrifying contribution to the songbook.

"Although the exact identity of the trace maker of the Shibantan trackways is hard to determine in the absence of body remains at the end of the trackways, we suggest that the trace maker was probably a bilaterian animal with paired appendages", the authors reported.
