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.

Has Canada’s stand on Israel-Palestine conflict cost it the UNSC Seat

On the 17th of June, 2020, Canada lost its bid for a temporary seat in the UN Security Council, the only UN body which can put binding resolutions on the member countries.. In the competition were Norway and Ireland, which won by 130 and 128 votes respectively where the votes required to secure a seat were 128. Canada, however, fell short by 20 votes.

It is a jolt to Canadian Prime Minister Justin Trudeau who had declared “Canada is back” to the world stage after the conservative government. He had personally campaigned for the seat but Canada received even fewer votes than what it received in 2010 under the conservative government of Stephen Harper. That is why Bessma Momani, a senior fellow at the Centre of International Governance and Innovation, calls it “embarrassing” and a “bit of a wake-up call.”

There have been many mixed reactions within Canada on the reason for the loss as well as the significance of this loss.

A professor at the Munk School of Global Affairs at U of T, Jance Stein, talks about how Canada in UNSC would have got trapped in the crossfire between US-Canada clashes. Andrew MacDougall, the ex-director of communications with the former PM Harper, says “UNSC hasn’t been relevant to global peace and security for more than 15 years”, implying that UNSC seat is not worth much.

There have been many reasons ascribed to the loss, the first and foremost being Canada’s staunch support of Israel. Canada has voted 116 times against UN resolutions for Palestinian rights, against Israel’s occupation, since 2000. It has also not opposed Israel’s planned annexation of the Jordan valley. “Just Peace Advocates” in association with over a hundred non-governmental organizations sent a signed letter to UN members countries, urging them to consider Canada’s votes against Palestinian refugees and illegal settlements while deciding on their votes for UNSC seat. It also pointed out how Canada considers Israel’s illegal territories as a part of it in trade, which is directly against UNSC Resolution 2334 which calls on member states to distinguish between Israel and its new territories occupied in 1967. As majority of the countries in UN show support for the Palestinian cause of a separate state and the well being of the war-wreckin Palestinian citizens, Canada’s unwavering support for Israel might have contributed to its defeat in winning UNSC seat.

Tamara Lorincz, a member of the Canadian Foreign Policy Institute pointed towards a more fundamental issue with Canadian foriegn policy management. He talked about how Canada hasn’t drafted a foreign policy to explain its stances on important global issues, hasn’t set aside enough funds for overseas development aid, has exported weapons to countries like Saudi Arabia, has snubbed negotiations on a treaty against nuclear weapons and many other shortcomings which make it undeserving of the seat.

This development, however, is beneficial for the Palestinians, since Canada would have supported Israel in the UNSC and opposed all such resolutions which may favour Palestinians and are critical to Israel. This loss may also force Canada to give a serious rethink to its Israel First policy. According to a poll by EKOS Research Associates, three in four Canadians want their government to oppose Israel’s annexation plans and 42% of them wanted sanctions against the country. There is also a campaign in Canada which calls on the Prime Minister “to fundamentally reassess Canadian foreign policy.”

It is too early to predict whether the loss of the UNSC seat will trigger some introspection in the foriegn policy circles of Canada or it will be business as usual.
