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.

Why the neighbours are furious with Hungary’s pre-World-War 1 map display

In the first week of May, 2020 the Prime Minister of Hungary, Victor Orban, conveyed his best wishes to the students appearing in history examinations. He may or may not have anticipated that his facebook post would create such fierce reactions in the neighbouring countries.

The controversial image, posted on Facebook, showed European countries of Croatia, Serbia, Romania, Slovakia and Slovenia within the borders of Hungary These countries came into existence when Austro-Hungarian state lost the World-War and signed the Treaty of Trianon in June, 1920 which envisaged the breakup of the empire.

Zoran Milanovic, the President of Croatia, was quick to respond to the post which persuaded the students of his country against posting such maps of Croatia which might ‘irritate’ the neighbours. “In our closets and archives there are numerous historical maps and maps that show our homeland much bigger than it is today … Don’t share them and put them on your profiles” he said.  

On the other hand, Ludovic Orban, Prime Minister of Romania, retorted in a very ironic manner. “The sparrow dreams of the dough” he said, referring to a Romanian proverb which means that Victor was just trying to put Transylvania, now in Romania, back in the Hungarian territory.

It is important to note that Romania is home to a large group of ethnic Hungarians and the loss of Transylvania is still a highly poignant matter for Hungary.

Daniel Bartha, from the Budapest-based Centre for Euro-Atlantic Integration and Democracy (CEID) thinks that there probably was no dual meaning rendered by Orban’s post. He said, “If there was a message in this, it was not intended to send it to other countries but it was a message to Romania… it is kind of a response to the ongoing clashes with Romania over the minority rights of Hungarian people living in Romania.”

Borut Pahor, Prime Minister of Slovenia said. "It is understandable and right that the recurring postings of maps which could be understood as an expression of territorial claims are met with rejection and concern by the democratic public and politics, including me as the president of the republic" .

Sebian Member of Parliament, Aleksandra Jerkov, called upon Aleksandar Vucic, President of Serbia, to lodge a protest against Orban regarding this issue.

It is worth mentioning that such controversial maps were displayed earlier as well by Victor Orban. In June, 2019, Orban’s office tweeted a picture of a similar map to celebrate Hungarian Day of National Unity, the day on which the Treaty of Trianon was signed. In December 2019, a Facebook photo posted by Orban showed a meeting of his party in progress under the same map.

The use of controversial map by Victor Orban fits perfectly well in his time tested strategy of using ultra nationalistic symbolism for solidifying his support base and continue to rule Hungry with an iron fist.
