Scientists find 74-million-yearold mammal fossil in Chile
Scientists have discovered the fossil of a tiny mousesized mammal that lived in the time of the dinosaurs in Chilean Patagonia. 'Yeutherium pressor ' weighed between 30 and 40 grams (about one ounce) and lived in the Upper Cretaceous period, about 74 million years ago. It is the smallest mammal ever found in this region of South America, dating back to the era when it was part of a continental land mass known as Gondwana. The fossil consists of 'a small piece of jaw with a molar and the crown and roots of two other molars,' said Hans Puschel, who led the team of scientists from the University of Chile and Chile's Millennium Nucleus research center on early mammals. The discovery was published this month in the British scientific journal Proceedings of the Royal Society B. Researchers found the fossil in the Rio de las Las Chinas Valley in Chile's Magallanes region, about 3,000 kilometers (1 ,864 miles) south of Santiago. Despites its similarity to a small rodent, 'Yeutherium pressor' was a mammal that must have laid eggs, like the platypus, or carried its young in a pouch like kangaroos or opossums. The shape of its teeth suggests that it probably had a diet of relatively hard vegetables. Just like the dinosaurs with whom it co-existed, the tiny mammal abruptly went extinct at the end of the Cretaceous period, about 66 million years ago. This illustration, created by Mauricio Alvarez and obtained from Universidad de Chile depicts the 'Yeutherium pressor,' an animal that lived during the Late Cretaceous period, approximately 74 million years ago.

Scientists Uncover Fossil of Tiny Mammal in Chilean Patagonia
Rana Atef Scientists in Chile have discovered the fossil of a mouse-sized mammal that lived alongside dinosaurs around 74 million years ago in Chilean Patagonia. Named Yeutherium pressor, the tiny creature weighed between 30 and 40 grams and is the smallest mammal ever found in this part of South America, which was then part of the ancient supercontinent Gondwana. The fossil — a small jaw fragment containing one molar and the crown and roots of two others — was unearthed in the Río de las Chinas Valley, in the Magallanes region, some 3,000 kilometers south of Santiago. Lead researcher Hans Puschel, from the University of Chile and Chile's Millennium Nucleus center for early mammals, said the discovery sheds light on the region's prehistoric biodiversity. The findings were published this month in the Proceedings of the Royal Society B. Despite its rodent-like appearance, Yeutherium pressor likely laid eggs, like a platypus, or carried its young in a pouch, like kangaroos and opossums. The shape of its teeth suggests it fed on hard vegetation. Like the dinosaurs it lived alongside, the tiny mammal disappeared in the mass extinction that ended the Cretaceous period around 66 million years ago. read more Gold prices rise, 21 Karat at EGP 3685 NATO's Role in Israeli-Palestinian Conflict US Expresses 'Strong Opposition' to New Turkish Military Operation in Syria Shoukry Meets Director-General of FAO Lavrov: confrontation bet. nuclear powers must be avoided News Iran Summons French Ambassador over Foreign Minister Remarks News Aboul Gheit Condemns Israeli Escalation in West Bank News Greek PM: Athens Plays Key Role in Improving Energy Security in Region News One Person Injured in Explosion at Ukrainian Embassy in Madrid Videos & Features Story behind Trending Jessica Radcliffe Death Video News Israeli-Linked Hadassah Clinic in Moscow Treats Wounded Iranian IRGC Fighters Arts & Culture "Jurassic World Rebirth" Gets Streaming Date News China Launches Largest Ever Aircraft Carrier News Ayat Khaddoura's Final Video Captures Bombardment of Beit Lahia Business Egyptian Pound Undervalued by 30%, Says Goldman Sachs Videos & Features Tragedy Overshadows MC Alger Championship Celebration: One Fan Dead, 11 Injured After Stadium Fall Arts & Culture South Korean Actress Kang Seo-ha Dies at 31 after Cancer Battle Lifestyle Get to Know 2025 Eid Al Adha Prayer Times in Egypt Arts & Culture Lebanese Media: Fayrouz Collapses after Death of Ziad Rahbani
