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.

Late Sultan Qaboos’s Legacy And What’s Next For Oman

On the morning of January 11, 2020, the citizens of Oman awoke to the news that Sultan Qaboos Bin Said, the monarch of the small Gulf nation, had passed away the previous day after a 49-year rule.

The late Sultan Qaboos came to power in 1970, after he overthrew his conservative father in a palace coup with the help of the British. He then set about modernising his impoverished country, using Oman’s newfound oil wealth to fund its infrastructure. When he took over the throne, Oman had only three schools and harsh laws banning electricity, radios, eyeglasses and even umbrellas. By the time he left, Oman developed a good education system, a robust economy, and has become a tourist destination.

Apart from bringing about this ‘renaissance,’ Qaboos also gained worldwide fame for championing neutrality and constructive diplomacy. Despite being located in the Strait of Hormuz in the turbulent Middle East, he maintained relations with countries ranging from Saudi Arabia, Qatar, Iran, Israel, and Palestine, and also with the Houthi rebels in Yemen. Perhaps the greatest result of this long-standing policy was enabling backchannel talks between the US and Iran which led to an international nuclear deal.

Sultan Qaboos also introduced democratic institutions in Oman, issuing the country’s first constitution, granting universal suffrage to all citizens above 21, and allowing the country’s first municipal elections in December 2012. However, he also suppressed dissent to the extent of shutting down news outlets and arresting protestors, journalists and activists, sometimes for opinions expressed on social media.

Oman experienced ripple effects of the Arab Spring in the form of months of protests against corruption and unemployment; and eventually Sultan Qaboos relented by giving more legislative powers to the Council of Oman and promising to increase wages and create jobs. While this satisfied the protestors, it did not mean life under ‘Baba Qaboos’ was all roses and no thorns for everyone. As detailed in this 2020 Periodic Review by Human Rights Watch, Sultan Qaboos revised Oman’s penal code in January 2018, which included “increasing punishments for offenses that relate to the peaceful exercise of freedom of expression.

The last few years of Qaboos’ rule saw economic stagnation and a crash in global oil prices which resulted in high youth unemployment rates  in a country where a significant portion of the population is under the age of 25. The large budget deficits and high debt have prompted the rating agencies such as Moody’s to downgrade Oman’s credit rating to ‘junk’ status. In an attempt to reduce the dependence on oil, Sultan Qaboos launched ‘Vision 2020’ to encourage innovation in other areas. This initiative failed to meet the objective and got renamed as ‘Vision 2040.’

This was the scene laid out for the new Sultan Haitham Bin Tarik, who was designated the new ruler of Oman as per a secret envelope containing late Sultan Qaboos’ choices for his successor.

Haitham bin Tarik was the Minister of Heritage and Culture before his accession to the throne, and also happens to have been the Chairman of the ‘Vision 2040’ committee, among other posts. In his first royal speech, he vowed to continue in the footsteps of his predecessor, especially in regards to the state’s foreign policy. In another royal speech in February, he charted a ‘future roadmap’ for Oman and claimed that he will prioritize education and youth employment. He has been active in these past six months, having issued 70 Royal Decrees concerning appointments, amendments, and new laws, among others.

Sultan Haitham is already being put to the test as Oman battles the COVID-19 along with the rest of the world. Omanis are looking at a new vision with renewed hope, one of the new sultan who brings with him great promises and perhaps a renaissance of its own kind. Will Oman be able to maintain its tradition of neutrality? Will the fight for a progressive and inclusive Oman find its voice? Will Oman be able to save itself from the consequences of a glut in crude oil economy? The citizens of Oman hope and wish that their new sultan will get the right answer and steer the country towards a more secure and prosperous future.
