Moon-like crater found in US from ‘tremendous impact BEFORE the dinosaurs’

A new study has discovered that a Cluster of craters never seen on Earth has been discovered in the US state of Wyoming.

The studytitled Secondary Barrel Damping on Earth: The Wyoming Crater Field, was published last week in the Bulletin of the American Geological Society.

Secondary craters never seen on Earth have been discovered in Wyoming.

The discovery was made in a 40 km x 90 km area that scientists call the Wyoming Impact Crater Field, just outside the cities of Casper and Douglas.

According to the team of researchers, which includes both American and German scientists, the field of several dozen craters is thought to have formed from some kind of strong impact about 280 million years ago.

Scientists also seem to believe that the 31 craters, between 10 and 70 meters in diameter, are ‘secondary craters’ arising from a larger primary crater.

The secondary craters are baffling researchers, according to the study, because while they contain “corresponding shock characteristics,” they are missing meteorites.

However, the researchers believe they may have formed through “launch material,” or material ejected from the main crater.

Project leader Thomas Kenkmann, professor of geology at the University of Freiburg, Germany, said: “The orbits point to a single source and show that craters are formed by masses ejected from a crater large primary.

Also puzzling is that secondary craters are commonly found on celestial bodies like the Moon and Mars because they contain zero to thin atmospheres, so finding them on Earth, where thick atmosphere, is a strange and rare occurrence.

The scientists note in this study: “This is, for the first time, evidence provided that secondary barreling can occur on Earth.

“Secondary craters around larger craters are known to other planets and moons but have never been found on Earth,” said Kenkmann.

Secondary impact craters differ from primary craters in that they have shallower depths, as well as ray-like patterns.

The team of scientists explained in the study that they used satellites, drones, geological field investigations, microscopic analysis and modeling to collect their data.

As a potential next step, the team proposed a “comprehensive geophysical survey of the deep basin north of Denver” to determine the location of the main crater.

They also encouraged the hydrocarbon exploration industry to “actively support and accompany the search for the main crater and the reporting of unusual incidents.”
