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.

How is Nigeria fighting Boko Haram

It was in the 2000s that Nigeria first faced the threat of Boko Haram, the affiliate of Islamic State in Africa. As President Muhammadu Buhari completes five years of being in power, which he got primarily for his plank of defeating Boko Haram, the battle still continues.

Buhari won the presidential election in 2015 against then President Goodluck Jonathan by touting his military background as an asset in defeating Boko Haram, which his predecessor was not able to do. While in his first few months as President he did show results by pushing Boko Haram out of some territories, the Nigerian military was unable to maintain the momentum as Boko Haram struck back with new tactics.

There is widespread distrust towards government officials and Buhari’s popularity has also eroded massively. The citizens are making their dissatisfaction known through anti government demonstrations. Meanwhile the administration seems busy playing blame games and guessing at where things are going wrong in the military’s efforts to contain the violence.

In June 2020, Nigeria saw one of its deadliest attacks in recent times, a hard turn from claims by the military in April that a Boko Haram leader appeared ready to surrender “based on body language.”

Boko Haram which means "Western education is prohibited" in the local Hausa dialect, first began in 2002 under Muhammad Yusuf. They called shunning the western influence in the social sphere and called  for the enforcement of sharia even among non-Muslims. Its leader Mohammad Yusuf was killed in police custody in 2009. However the government authorities failed to utilise this opportunity and showed slackness in rehabilitating the group members, who moved underground, regrouped under new leadership, and continuing to terrorise even larger areas.

Many factors have been considered in piecing together what led to the creation of Boko Haram and how its existence has been sustained, ranging from support from ISIS, ability to internationalize as a group, and possible assistance from Libya.

The US and Europe have been seen as reluctant to extend any real aid, perhaps due to Nigeria’s oil reserves and a desire to keep African countries destabilised to maintain their neo-colonial stronghold in the region. Internally, corruption and laxity in action of troops has often been cited as big hurdles in controlling the situation.

As for solutions, many have turned their focus towards rebuilding communities in the aftermath of thousands of people being murdered and displaced due to the ongoing violence. Not just civilian casualties, but a disastrous lack of necessities such as food, water and electricity is leading to a humanitarian crisis in the area falling in the conflict zone between Boko Haram and the military.

President Buhari currently seems slow to admit that Boko Haram cannot be “defeated on the battlefield alone.” Apart from improving the military’s response he must also take measures for alleviating poverty, destroying corruption and ‘de-radicalisation’ of those recruited into Boko Haram.

Some localised efforts are being taken to stabilise the situation by empowering communities to resolve conflicts, improving civil infrastructure, and reintegrating reformed militants.

However, localised efforts are short-term in nature, and their stability and success is greatly determined by the government which understands that more than killing the attackers, trust and active participation of its citizens is needed to resolve this conflict

The impact of Boko Haram on the people of Nigeria has been multifold, and the arsenal to ‘defeat’ Boko Haram must be expanded and redefined.
