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.

Trump’s “Israel-Palestine Peace Deal”: Cheered by Israelis and Jeered by Palestinian Authority

In January 2020, President of the United States, Mr. Trump, elaborated on a plan that, according to him, would bring peace to the Middle East with respect to the ongoing Palestinian crisis. The plan was welcomed by Israel but rejected by the Palestinians as they perceive it to favour Israel at the cost of Palestinian interests. It gave Israel the right over Jerusalem and the settlements in the West Bank as well as Jordan Valley. The settlements in the West Bank came as a consequence of the 1967 Mideast war, in which Israel had captured it but never formally claimed it due to international opposition. 

According to the plan, the proposed Palestinian state would not have a standing military and would be required to live up to benchmarks set up by the Israelis. The new state of Palestine will be established on the land which is non-contiguous and Israel would retain the security responsibility of the West Bank. The new Palestine therefore will become unviable as a functioning state.  

The president of the Palestinian authority, Mahmood Abbas, denounced the plan immediately and called it a conspiracy deal which is unworthy of serious contemplation. “We say a thousand times over:”, he said ”no,no,no,” after which the Palestinian leadership has not been on speaking terms with the Trump administration. Mr. Abbas played no substantive role in the plan-making process.

In January, Israel was planning to vote on the unilateral annexation of the West Bank after their Knesset elections, which is the national legislature of Israel. Benjamin Netanyahu, the Israeli prime minister who promised the annexation if he was elected, was re-elected in the March elections. "Today, I announce my intention, after the establishment of a new government, to apply Israeli sovereignty to the Jordan Valley and the northern Dead Sea," said Mr. Netanyahu in September as a part of his election campaign.

The annexation, in the opinion of the Prime Minister of Palestine, would destroy the progress made in the Oslo accords, which were agreements between the two states signed in 1993. On 20th of May, the Prime Minister vowed to annex parts of the occupied West Bank and that he’d act in July, to which the Palestinian authority dissolved all treaties, understandings and agreements with Israel and the United States, which include the Oslo accords.

In the beginning of June, the Palestinian Prime Minster announced that the state would declare independence for Palestine if Israel follows through on the threat. The announcement detailed that the authority would declare an independent state along the 1967 partitions with Jerusalem as its capital. The authority would also manifest as a state on the ground, which means there would be a founding council and a constitutional declaration. 

All eyes are now on the action of Israeli government and reaction of Palestinian Authority in this  long drawn saga.
