In a village in the eastern cape of South Africa lies one of the most significant dinosaur sites ever found in the world. The site was discovered when a shepherd, Dumangwe Thyobeka found a large bone on his way to his great-grandparents’ graves, in 2015. He then took the bones to a local dinosaur enthusiast, James Rhalene. Commenting on this discovery " Mr. Rhalene said, "Growing up we were told dinosaurs were a myth, I thought they were only tales our grandparents would tell around the fire at story time", and It wasn't until reading some books that I started to believe they may be real. I've been looking into the existence of dinosaurs since 1982. He added, "You can imagine my excitement at being part of this and discovering them in my own backyard. I am so proud. Books will be written about our small village; the world will come to know of us through this discovery.”

These bones are more than 200 million years old, of around the end of the Triassic era and the beginning of the Jurassic one. When the village elder, Sginyane Ralane came to know about the discovery, he reached out to universities in South Africa for looking into it. The news eventually reached Prof. Jonah Choiniere from the University of Witwatersrand in Johannesburg, and in 2018 Jonah and his colleagues started excavating the site. “It has been one of those places where you sometimes find yourself literally tripping over a dinosaur bone. There are very few other sites I've had the chance to work where we have this richness of fossils.” says Prof Paul Barett, a dinosaur expert at The Natural History Museum, UK, after he joined the team.

A reason why this area is abundant in fossils, Natural History Museum explains, is because of the ancient river systems in the area. The area is arid for most of the year now, and the rivers flow only seasonally. However, in the ancient times, there were vast river systems flowing year-round in the region, with wide, shallow rivers which would consequently form a layer of rock 210 million years old which is up to 500 meters thick in some regions. These rivers supported diverse wildlife, including ancestors of crocodiles, possibly those of turtles and mammals and fish, amphibians and reptile-like animals. The existence of such large rivers meant that dead animals nearby would be buried in sediment before they decomposed.  

This discovery is scientifically important for a number of reasons; the era from which these bones are found is a boundary in which a mass extinction occurred. Prof. Jonah is trying to understand how the animals from before that extinction survived and how they flourished after. In the Triassic era, there were multiple dominating animals, like the crocodiles, big mammal-like animals and dinosaurs. In the Jurassic era, however, the dinosaurs are clearly dominating. Why this happened is unclear, and the rocks and fossils from this site might help with that. There were also other animals along with dinosaurs in this site which make it noteworthy. Of the animals found, there were rauisuchians, which relate to modern-day crocodiles, and were dominant on land during the Triassic. The team also found cyclodonts and dicyclodonts, where the cyclodonts are the early ancestors to all mammals, and dicyclodonts are an even earlier branch of the mammalian family tree.

All of these have a significant impact on the community too; the team signed a memorandum of understanding with the local government with huge. After the signing, local officials visited the site at Qhemega. The team has been trying to use the heavy machinery they had brought for moving fossils for improving access in and to the village. They are also developing a curriculum in high schools to include topics about fossil sites and to add geography to the curriculum, to train the younger generation about the mapping used in excavation and in many other scientific fields especially relevant in the mineral-resource rich South Africa.

So far, this site has only provided benefits for everyone involved; new discoveries and confirming data for the scientific community, and economic access, increased opportunities and a matter for pride for the local community.

Black Lives Matter: Why "All Lives Matter" is a False Equivalence

The phrase “All Lives Matter”, used in response to the slogan “Black Lives Matter”, has been causing a lot of controversy. The slogan is sometimes used by “colour-blind” people, who do not see colour as a basis of any of their decisions, and when they hear “Black lives Matter”, they want to add white lives to the mix, not understanding that race causes significant differences in what people face with respect to discrimination. 

In one of the incidents, a man spray-painted ‘White Lives Matter’ on the statue of Arthur Ashe, an African American Tennis legend, who was the first black Wimbledon men’s singles champion. After the man left, some people spray-painted “Black Lives Matter” over the previous paint. The man returned in a while to wipe off that message, and when asked why he had painted “white lives matter” on the statue. According to the video, the man replied "Don't all lives matter? Why is it okay to spray paint on this statue 'black lives matter,' but not 'white lives matter'? What's the difference? They all matter. Everybody matters, right?"

However, John Hayward on Breitbart throws a different light on the use of the all lives matter slogan. It talks about several instances of how people and organizations have used the phrase, like how the local authorities in Frankton, Indiana tried to have it on the side of the police cars out of general goodwill, and did not realize that the phrase was offensive to the Black Lives Matter movement.

The phrase “All Life Matters” may have been used as a slogan for joining all hands together, and expressing the fundamental right to equality. However it is found to be misguided and offensive by many people because they feel that the phrase invalidates the specific difficulties faced by the black community. For explaining this, they draw a comparison: if there is one house burning, if the other houses call out that they want the water poured on them too, that’s just counterintuitive and ignoring the burning house. Another comparison is that at a dinner table, a child has half a portion and the other has a whole. When giving another half a portion to the child with less food, if the other child demands half a portion too, it is evident that the child with the full portion is ignoring the fact that the other one has only the half. 

The intention about the usage of the phrase “All Lives Matter” doesn’t matter; it still negatively affects the “Black Lives Matter” movement. Speaking of “All Lives Matter” in response to someone asserting that “Black Lives Matter” is walking over the struggles that black people specifically face and it is a false equivalence.
