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.

What If Trump Loses The Election... And Decides To Fight The Result

In an interview in July 2020, Donald Trump, President of the United States, told an American TV host, Chris Wallace that he is “not a good loser,” when asked about the possibility of the November Presidential election results not being in his favour. “I am not going to just say yes. I’m not going to say no.”

Since he began his run for President in the 2016 elections, Trump has been extremely vocal about claiming rigged elections even after he won, and that Democrats have set out to make him lose through a variety of alleged means. Similarly in this election, he has continuously claimed that expansion of absentee and mail-in ballots will ‘corrupt’ the election. Even before the pandemic, as early as May 2019, there were concerns that Trump won’t allow for an easy transition of power, to the extent that Speaker Nancy Pelosi had to comment on them.

It’s possible Trump has been escalating this rhetoric because his COVID-19 mismanagement among other things, has put him behind his rival Joe Biden in national polls. It is bad enough that a President is questioning the integrity of elections with little to no proof to back up his exaggerations, but this will almost definitely lead to the people of the country— whether his supporters or not— distrusting the elections as well.  

Despite the absentee and mail-in ballots being provided due to the coronavirus pandemic, to enable social distancing and to allow people to vote safely from home. Trump has often played down the coronavirus pandemic, and called Anthony Fauci, the National Institutes of Health expert on infectious diseases, an “alarmist” for raising issues pertaining to COVID-19.

The chances of an “electoral meltdown” are slim, but not impossible; the right (or wrong) mix of factors can lead to disaster. Lawrence Douglas, professor of law, jurisprudence and social thought, at Amherst College, Massachusetts. imagined a scenario where the difference between Trump and Biden rests on swing states and mail ballot results. Given the chance of a higher than usual number of mail-in ballots this year due to the pandemic, delays in counting votes are to be expected. Trump wouldn’t be slow to claim rigged elections and refuse to wait for all votes to be counted and right-wing media wouldn’t be slow to broadcast this everywhere.

In a closely fought election like this US Presidential election , the ‘Swing states’ (where both parties enjoy similar levels of popularity) will play a major role in the outcome. Three of the major swing states in America: Michigan, Wisconsin, and Pennsylvania have Republican lawmakers but Democratic governors. Each state is required to submit electoral certificates declaring the election winner in their state. By the time all votes are counted, Republican legislatures and Democratic governors might end up submitting conflicting election results for the same state.

A similar stalemate had occurred in 1876. It led to a “disastrous” compromise and the 1887 Electoral Count Act, which, according to Professor Douglas, may prove deficient in preparing for an impasse like the one that currently looms in the realm of possibility.

If Trump were to challenge the result he might have a few options for his course of action. He could challenge the results in court, as happened in 2000 in the state of Florida. Or, Republicans in state legislatures might use the Constitution to override the decision of the popular vote.

According to speaker Nancy Pelosi, Democratic nominee Joe Biden, and some Trump campaign spokespeople believe that Trump will accept the results of the election but do not rule out the possibility of him putting up a fight.

For others, given what is known about Trump’s behaviour, it’s more or less anticipated that he, and his twitter, will be raging with a lot of accusations if he loses the election, especially if it happens by a close margin. The important questions related to what he chooses to do about it and who backs him up.
