The aforementioned fossilized skull was first discovered in Zambia in 1921. Broken Hill was regarded as a main discovery back then. It was located specifically in a place called Broken Hill hence the name. Broken Hill was in fact the earliest recovered fossil of an extinct human species in the African continent.

Scientists note that a later assessment insinuates that Broken Hill is much younger than initially concluded by the experts. The previous age estimate of the skull was about 500,000, whereas the current estimate is about 299,000 years old with which the team used two new comprehensive dating methods. They add that the new findings affect how the tempo and mode of modern human ancestry were previously perceived.

As explained by the researchers, they found Broken Hill difficult to examine because it was found in a mining site that got massively ruined due to mining operations later on.

With data gathered from NASA’s Hubble Space Telescope and two X-ray observatories, researchers located the black hole in the act of annihilating an adjacent star. Black holes are immensely dense matters with powerful gravitational pulls even light cannot get away with.

This latest discovery has a mass that is 50,000 times more than that of our sun. It is situated more or less 740 million light-years from our planet in another galaxy where there are fewer stars.

Scientists have been looking for mid-size black holes for 40 years. Yet, less than 10 of them have been discovered. They believe that several objects similar to this exist, and are just waiting to be discovered. They noted that the phenomenon of a black hole swallowing a star is such a rare occurrence that it takes place only once in 10,000 years on average.

Fossilized skeleton samples aided the researchers in charge to comprehend the history and development of the ancient animals on a deeper level. They detached thin parts from the leg bones of the two dinosaurs. Then, they studied the bone pieces under a microscope. The experts explained that examining the microstructure of the fossils provides significant information about the growth rate, age, and metabolism of the creature.

Based on their findings, young T. rex dinosaurs would move around swiftly and had teeth similar to a knife, while a fully-grown counterpart had teeth that could squash huge bones. In addition, an adult T. rex can grow up to 12 meters long and 5 meters tall.
