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.

Civilian Trials In Military Courts in Al Sisi’s Egypt

With President Abdel Fattah al-Sisi in power, Egypt is currently in the throes of a near-complete reversal of democracy. Under his rule the military has intruded into almost all aspects of public life, in a very explicit attempt to instill fear in Egyptians.

One of the most pervasive examples of this has been the military’s disruption of judicial process, with interference turning to encroachment as more and more civilians continue to be tried and sentenced by the army, through various nefarious means of expanded military jurisdiction.

While a military judiciary has been present in Egypt since the 1960s, their power continued to grow after then Defence Minister Sisi overthrew the democratically elected President, Mohammed Morsi in a coup and became Egypt’s new leader. Since then he has worked towards removing tenure limits to his term, virtually guaranteeing him power for another decade or more.

The Egyptian government, like many others across the globe, has used the pandemic and the limited mobility of citizens due to it to tighten their chokehold on dissent and opposition. In April 2020, the Egyptian Parliament passed amendments to its Emergency Law. The law already prohibited demonstrations and protests, and now allows the military to arrest and confiscate assets of citizens without requiring permission from the special prosecutor, and investigate civilians without the right to appear before a judge.

Egypt has seen more time under Emergency Law than not in the past few decades, and President Sisi has not strayed from this pattern. The law has been used in many ways to normalize the military trespassing into the civil judicial system, such as having military judges on civil judicial councils and declaring the military judiciary as “an independent judicial entity” no longer under the command of the armed forces.

Public facilities have been placed under military jurisdiction, in conjunction with a law that allows anyone who directly or indirectly “assaults” an army base to be tried in a military court. In these courts defendants do not have common legal rights such as being informed of their charges, access to a lawyer or being brought before a judge soon after arrest.

Additionally, there have been multiple reports of torture, sexual assault while placed in detention. In prison too, detainees face inhumane conditions, not being allowed to see family, exercise or get sunshine and fresh air. Thousands of student protestors, journalists and political dissidents have been tried in these military courts, and hundreds more have been killed extrajudicially. At the same time, citizens’ tools to criticise these steps are undermined, such as by limiting the domain of NGOs, censoring news and social media, and blocking around 600 websites.

The arrest, incarnation and trial of the deposed President, Mohammed Morsi is a glaring example of what is wrong with Egypt’s military trials. Morsi, who was in jail for over 6 years since the coup in 2013 and was under trial in military court collapsed and died during a hearing in the military court itself.

The constitution, the parliament, the law, and the abuse of these pillars of democracy has been instrumental in Sisi being able to give the military and himself the extreme power that they now possess. But despite restrictions on assembling and protesting, Egyptians continue to make their voices heard in the streets and worldwide, hoping that where institutions betray them, their community won’t. Hoping against hope, hoping against tyranny.
