Discovery of 120-Million-Year-Old Microraptor Fossil Expands Understanding of Dinosaur Evolution

Discovery of 120-Million-Year-Old Microraptor Fossil Expands Understanding of Dinosaur Evolution

A 120-million-year-old fossil of a microraptor, named Jian changmaensis, has been discovered in the Changma Basin of northwestern China. This finding is significant as it expands the known geographical range of microraptors, a group of predatory dinosaurs closely related to the velociraptor. The fossil, which includes intact shoulder and forelimb bones, represents the most recent definitive microraptor specimen in the fossil record. The research, published in the Annals of Carnegie Museum, highlights the birdlike characteristics of this dinosaur, which had feathers covering its body and long feathers on its hind legs, suggesting it could glide between trees. This discovery provides new insights into the origins of avian flight and the evolution of birds.

Newly Discovered Microraptor Fossil Sheds Light on Dinosaur Flight Evolution

Newly Discovered Microraptor Fossil Sheds Light on Dinosaur Flight Evolution

A newly identified species of microraptor, named Jian changmaensis, has been discovered from a 120 million-year-old fossil in northwestern China's Changma Basin. This gliding dinosaur, about the size of a barn owl, is believed to have hunted birds and represents a significant find in understanding the evolution of flight in dinosaurs. The fossil, which includes well-preserved shoulder and forelimb bones, suggests that microraptors were capable of gliding between trees. The discovery expands the known geographical range and timeline of microraptors, providing new insights into their ecological role and evolutionary history.

Fossil Discovery in China Reveals New Microraptor Species, Expands Understanding of Avian Flight Origins

Fossil Discovery in China Reveals New Microraptor Species, Expands Understanding of Avian Flight Origins

A 120 million-year-old fossil discovered in northwestern China has unveiled a new species of microraptor, named Jian changmaensis. This discovery expands the known geographical range of microraptors, which are smaller, gliding relatives of the velociraptor. The fossil, found in the Changma Basin, is the first microraptor specimen discovered outside northeastern China. The research, published in the Annals of Carnegie Museum, highlights the birdlike characteristics of Jian changmaensis, which had long feathers on both its arms and hind legs, suggesting it could glide between trees. The study provides new insights into the origins of avian flight, as microraptors are closely related to the ancestors of modern birds.

Fossil Discovery Reveals Kraken-like Octopus from 72 Million Years Ago

Fossil Discovery Reveals Kraken-like Octopus from 72 Million Years Ago

Scientists have discovered fossilized jawbones of Nanaimoteuthis haggarti, a massive, kraken-like octopus that lived approximately 72 million years ago. Found in Japan's Yezo Group and Canada's Nanaimo Group, these fossils suggest that these cephalopods were among the largest marine creatures of the Cretaceous Period. The study, published in the journal Science, indicates that these invertebrates occupied the top of the food web, challenging previous views of Cretaceous marine ecosystems dominated by vertebrate predators.

Fossil Discovery Reveals Kraken-like Octopus as Top Predator 72 Million Years Ago

Fossil Discovery Reveals Kraken-like Octopus as Top Predator 72 Million Years Ago

Scientists have uncovered fossilized jawbones of Nanaimoteuthis haggarti, a massive, kraken-like octopus that lived about 72 million years ago. According to a study published in the journal Science, these cephalopods were among the largest marine creatures of the Cretaceous Period and might have been the largest invertebrates ever. The discovery was made in Japan's Yezo Group and Canada's Nanaimo Group geological formations. Researchers identified 12 additional fossil jaws and examined 15 previously found ones, dividing the creatures into two species based on size and form. The study suggests that these giant invertebrates occupied the top of the food web, challenging the view of the Cretaceous ocean as dominated only by large vertebrate predators.

Scientists Discover 40-Million-Year-Old Ant in Goethe's Amber Collection, Offering New Insights

Scientists Discover 40-Million-Year-Old Ant in Goethe's Amber Collection, Offering New Insights

Researchers have uncovered a 40-million-year-old ant fossil within Johann Wolfgang von Goethe's amber collection, using advanced 3D imaging techniques. The fossil, belonging to the extinct species Ctenobethylus goepperti, was found in exceptional preservation, allowing scientists to examine its anatomy in unprecedented detail. The study, conducted by the University of Jena, revealed fine body hairs and internal skeletal structures, providing new information about the species' biology and evolutionary history. The findings highlight the potential of historical collections to yield significant scientific discoveries.

Fossils Reveal Bryozoans' Presence During Cambrian Explosion

Fossils Reveal Bryozoans' Presence During Cambrian Explosion

Recent fossil discoveries in the Xiannüdong Formation of southern Shaanxi Province, China, have solved a long-standing mystery about the origins of bryozoans, tiny colonial invertebrates. These fossils, dating back to the early Cambrian period approximately 520 million years ago, confirm that bryozoans were present during the Cambrian explosion, a time when most major animal groups first appeared. The fossils include new specimens of Protomelission gatehousei and a new taxon, Dayingomelission hexaclitia. The preservation of these fossils is exceptional, with internal soft tissues intact, providing definitive evidence of their bryozoan affinity. This discovery fills a significant gap in the fossil record and suggests that bryozoans were already diversifying during the Cambrian radiation.

Largest Prehistoric Scorpion Identified from 415-Million-Year-Old Fossils

Largest Prehistoric Scorpion Identified from 415-Million-Year-Old Fossils

Fossils discovered in the U.K. have confirmed the existence of Praearcturus gigas, the largest scorpion ever known, measuring over a meter in length. This prehistoric scorpion lived during the Early Devonian Period, a time when life on land was just beginning to evolve. The research, published in Palaeontology, resolves a long-standing debate about the identity of these fossils, previously thought to belong to a giant crustacean. The study highlights the scorpion's role as a dominant predator in its ecosystem, capable of hunting both on land and in water, due to its large size and formidable pincers.

Huge Kraken-like Octopus may have ruled the seas 72 million years ago

A new study finds a giant octopus may have prowled the seas 72 million years ago and may have been at the top of the food chain.

Research Reveals Female Dolphins Avoid Aggressive Males During Mating

Research Reveals Female Dolphins Avoid Aggressive Males During Mating

New research has uncovered that female dolphins are able to remember and avoid aggressive males when selecting a mating partner. The study, conducted on a population of Indo-Pacific bottlenose dolphins in Shark Bay, Western Australia, highlights the complex social structures within dolphin communities. Female dolphins use the unique calls of males, known as 'signature whistles,' to track their past behaviors and avoid those with a history of aggression. This behavior is particularly evident during mating season when males often form alliances to herd females into consortships. The research, published in the Proceedings of the National Academy of Sciences, suggests that females prioritize their safety and foraging time by steering clear of coercive males.

Scientists reveal Ötzi the Iceman's dynamic microbial world

By Will Dunham June 3 (Reuters) - Ötzi the Iceman died violently roughly 5,300 years ago in the Alpine region of the modern border between Italy and Austria. An arrowhead was found lodged in his left shoulder, having caused fatal bleeding when he was attacked in mountainous terrain.
