Earth’s oldest animals formed complex communities

A new analysis is shedding light on Earth’s first macroscopic animals: the 570-million-year-old, enigmatic Ediacara biota. Ediacaran fossils have a slightly bizarre appearance not shared by any modern animal groups. For decades, researchers believed these enigmatic fossils were ecologically simple. However, borrowing a method from modern ecology — fitting species to relative abundance distributions — […]

Rare fossils give researchers insight into evolution of bird-like dinosaur

An international team of researchers discovered a new species of dinosaur, Xiyunykus pengi, during an expedition to Xinjiang, China. The discovery is the latest stemming from a partnership between the George Washington University and the Chinese Academy of Sciences. The findings were published today in Current Biology along with the description of a second new […]

WFS News: Early African Fossils Elucidate the Origin of Embrithopod Mammals

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Long before rhinoceros, giraffes, hippos, and antelopes roamed the African savannah, a group of large and highly specialized mammals known as embrithopods inhabited the continent. The most well known is Arsinoitherium, an animal that looked much like a rhinoceros but was in fact more closely related to elephants, […]

WFS News: Fossils of Pufferfish species unearthed in Germany

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists in southern Germany have discovered the fossilized remains of a previously unknown pufferfish. A team from the Bamberg Museum of Natural History made the find in a stone quarry in nearby Wattendorf. Matthias Mäuser, the head of the museum, said the pufferfish lived around 150 million years […]

WFS News: A unified model of the formation mechanism of spherical carbonate concretions contain exceptionally well-preserved fossils

@WFS,World Fosssil Society,Riffin T Sajeev,Russel T Sajeev Spherical, isolated carbonate concretions occur throughout the world in marine argillaceous sedimentary rocks of widely varying geological ages. These concretions are characteristically highly enriched in CaCO3compared to the surrounding sedimentary rock matrices and are typically separated from these rock matrices by sharp boundaries1,2,3. These sharp boundaries mean that […]

WFS News: Treasure trove of highly detailed fossils uncovered

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A team of researchers from Uppsala University have uncovered a hidden diversity of microscopic animal fossils from over half a billion years ago lurking in rocks from the northern tip of Greenland. The ‘Cambrian explosion’ of animal diversity beginning ~541 million years ago is a defining episode in […]

WFS News: Finger and toe fossils belonged to tiny primates 45 million years ago

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev At Northern Illinois University, Dan Gebo opens a cabinet and pulls out a drawer full of thin plastic cases filled with clear gelatin capsules. Inside each numbered capsule is a tiny fossil — some are so small they rival the diminutive size of a mustard seed. It’s hard […]

WFS News:Growing pains: The oldest trees on Earth ripped themselves apart, fossils show

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists have discovered 374-million-year-old tree fossils from the dawn of Earth’s forests — and found that these strange plants literally had to rip themselves apart as they grew. The fossils, described in the Proceedings of the National Academy of Sciences, shed light on the nature of ancient forests […]

WFS News:Fossils from the world’s oldest trees reveal complex anatomy never seen before

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The first trees to have ever grown on Earth were also the most complex, new research has revealed. Fossils from a 374-million-year-old tree found in north-west China have revealed an interconnected web of woody strands within the trunk of the tree that is much more intricate than that […]

WFS News: fossils shed light animal evolution on Earth

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists have discovered traces of life more than half-a-billion years old that could change the way we think about how all animals evolved on earth. The international team, including palaeontologist from The University of Manchester, found a new set of trace fossils left by some of the first […]
