Indonesian researchers unearth 500,000-year-old elephant fossils in Java
Jakarta: Indonesian researchers have discovered fossils of a prehistoric elephant in Central Java, which they estimate are around 500,000 years old.
The fossils were found in Patiayam, an archaeological site and mountainous area situated on the border of the Kudus and Pati regencies in Central Java, where, throughout the years, ancient animal fossils have been found.
In 2024, a collaborative team organized by the Center for Prehistory and Austronesian Studies, the Dharma Bakti Lestari Foundation and the National Research and Innovation Agency, known locally as BRIN, launched a research project at the site to explore fossil possibilities.
Though the initial discovery was made then, researchers postponed the project until this year and expanded the site of excavation, which is still ongoing.
'Based on the geological formation of the site where it was found, we estimate that the fossils are at least 500,000 years old, give or take. We have yet to conduct a direct dating of the fossils, so this is based on a relative dating of the soil layer,' Mohammad Ruly Fauzi, researcher at CPAS and BRIN, told Arab News.
'We have been able to identify that these belong to an elephas type, but not the specific species … What's clear is that this is a very big elephant, nothing like elephants today …. It's prehistoric, not early historic period.'
He said the excavation has made about 50 percent progress and that the elements found so far make up the front part of an elephant.
'It's interesting because this is shaping up to be an almost complete fossil … They are all situated pretty closely.'
Once the excavation is completed, the fossils will be preserved as part of a collection at the Patiayam Archaeological Museum. The discovery might help Patiayam gain recognition as a cultural heritage site, Fauzi added.
'Every site has its own unique qualities, but Patiayam site is particularly interesting and very deserving to gain status as a national cultural heritage site in our opinion … This research can help serve as a foundation for officials to decide,' he said.
Central Java, where Patiayam is located, is also home to the Sangiran Early Man Site, a UNESCO World Heritage site renowned for its significant collection of Homo erectus fossils, dating from 1.1 million to 800,000 years ago, including the 'Java Man.'

In Java, Indonesian conservationist leads efforts to protect endangered silvery gibbons
JAKARTA: It was deep in the heart of an Indonesian rainforest in West Java that Rahayu Oktaviani, known as Ayu, first heard the 'song' of the Javan gibbon. She had her first encounter in 2008 while visiting the Mount Halimun Salak National Park for an undergraduate research project that required her to obtain a voice sample of the primate. After waiting patiently for two weeks, coming in and out of the forest, she finally heard a Javan gibbon make its distinctive call. She recalled how the sound she described as melodic and haunting had created a hush, as it echoed throughout the forest. 'It's like the most beautiful song that I ever heard in my life. It's so amazing,' Ayu told Arab News. 'They are non-human primates, but they can have like this beautiful song that can make all of … the creatures in the forest just keep silent.' In the 17 years since, Ayu has dedicated her life to protecting the endangered animals, which are also known as 'silvery gibbon,' or 'owa jawa' locally. A vast archipelago stretching across the equator, Indonesia is a top global biodiversity hotspot and home to over 60 species of primates, about 38 of which are endemic to the country. 'Maybe a lot of people know about the orangutan, about the rhino, about the tiger, but how about the overlooked species, just like, for example, the Javan gibbon? Not so many people know about them,' Ayu said. Fewer than 2,500 Javan gibbons remain in the wild today, according to an estimate by the International Union for Conservation of Nature. About half of them live in the 87,000-hectare Mount Halimun Salak National Park, where Ayu and her team have laid the building blocks for grassroots conservation of the endangered species. The gibbons rely on a continuous canopy for movement and foraging, making them particularly vulnerable to forest fragmentation and habitat degradation. As around 55 percent of Indonesia's 270 million population lives in Java, the survival of the endemic species found only in the island's forests is threatened by deforestation and illegal animal trafficking. 'With the situation in Java, where only like 10 percent of the natural forests are remaining, it means the forest itself should be intact. The forest itself still needs to be there not only for the Javan gibbons, but also for the other species that need this habitat for their lives,' Ayu said. In 2020, she co-founded the conservation nongovernmental organization Kiara to expand efforts to save the Javan gibbon, believing that a key aspect in protecting the species was to engage the local community. When she started out as a primatologist, spending much time in the forest to study the gibbons, Ayu did not realize that she was neglecting the very people who lived alongside the primates. She recalled a question a villager posed at the time, a woman named Yanti, who was curious as to why Ayu always went to the forest but rarely stopped by the village. 'That's a really casual and simple question, but it kept me thinking about what I've been doing so far. Is there something that I've been missing?' Ayu said. Yanti's query eventually led her to realize that she needed to do more with the community. 'We want to build together with the communities, where actually the gibbon can be something that they can be proud of,' she said. 'Community engagement is 100 percent the core for conservation because without community, we cannot do everything.' Ayu has employed people from Citalahab, a small village enclave located within the national park where locals make a living working in tea plantations or as rice farmers. Eight of them now work in the field alongside Ayu and her team to monitor the gibbons in the wild. With Kiara, she also established the Ambu Halimun initiative, which involves 15 local women between the ages of 17 and 50 in ecoprinting workshops and financial literacy training. In April, Ayu won the prestigious Whitley Award, which recognizes achievements in grassroots conservation, to advance her work in protecting the Javan gibbons. With 50,000 British pounds ($67,000) from the award, Ayu plans to scale up her programs with Kiara to mitigate threats from human activities and to protect the gibbons' habitat. This includes developing a data management system to enhance park-wide conservation efforts, training the park rangers in biodiversity monitoring techniques, and guiding conservation strategies. The 38-year-old, whose role models are 'the Trimates,' primatologists Jane Goodall, Dian Fossey and Birute Galdikas, has faith that humans can live in coexistence with wildlife. 'Actually, if we put aside our ego, we are part of the ecosystem itself. We are not separated from the ecosystems, so it means we have to have more balance with nature,' she said. 'And to do that, we also have to respect what else (is) actually living together with us in these ecosystems.' Ayu said the Whitley Award served as good momentum to raise awareness about the species she loves dearly, the Javan gibbons. 'I believe not so many people are aware of the existence of the Javan gibbon, so it's the right momentum to share the love for the Javan gibbon and make people care about it,' she said. 'Because how can you care about the species if you know nothing about them?' With the award and the coverage that it garnered internationally, Ayu is also hopeful about inspiring a new generation of conservationists from Indonesia. 'I think women also play a good part to be conservationists in the future … It's also about … regeneration: the importance of nurturing the new generation of conservationists and primatologists from Indonesia, especially because we need more and more people who work in this field.'

New T-Rex Ancestor Discovered in Drawers of Mongolian Institute
Misidentified bones that languished in the drawers of a Mongolian institute for 50 years belong to a new species of tyrannosaur that rewrites the family history of the mighty T-Rex, scientists said Wednesday. This slender ancestor of the massive Tyrannosaurus Rex was around four meters (13 feet) long and weighed three quarters of a ton, according to a new study in the journal Nature. "It would have been the size of a very large horse," study co-author Darla Zelenitsky of Canada's University of Calgary told AFP. The fossils were first dug up in southeastern Mongolia in the early 1970s, but at the time were identified as belonging to a different tyrannosaur, Alectrosaurus. For half a century, the fossils sat in the drawers at the Institute of Paleontology of the Mongolian Academy of Sciences in the capital Ulaanbaatar. Then PhD student Jared Voris, who was on a trip to Mongolia, started looking through the drawers and noticed something was wrong, Zelenitsky said. It turned out the fossils were well-preserved, partial skeletons of two different individuals of a completely new species. "It is quite possible that discoveries like this are sitting in other museums that just have not been recognized," Zelenitsky added. They named the new species Khankhuuluu mongoliensis, which roughly means the dragon prince of Mongolia because it is smaller than the "king" T-Rex. Zelenitsky said the discovery "helped us clarify a lot about the family history of the tyrannosaur group because it was really messy previously". The T-Rex represented the end of the family line. It was the apex predator in North America until 66 million years ago, when an asteroid bigger than Mount Everest slammed into the Gulf of Mexico. Three quarters of life on Earth was wiped out, including all the dinosaurs that did not evolve into birds. Around 20 million years earlier, Khankhuuluu -- or another closely related family member -- is now believed to have migrated from Asia to North America using the land bridge that once connected Siberia and Alaska. This led to tyrannosaurs evolving across North America. Then one of these species is thought to have crossed back over to Asia, where two tyrannosaur subgroups emerged. One was much smaller, weighing under a ton, and was nicknamed Pinocchio rex for its long snout. The other subgroup was huge and included behemoths like the Tarbosaurus, which was only a little smaller than the T-rex. One of the gigantic dinosaurs then left Asia again for North America, eventually giving rise to the T-Rex, which dominated for just two million years until the asteroid struck.
