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 […]

WFS News: Evidence of Earthquakes recorded on fossils

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The Cascadia subduction zone (CSZ) has captured major attention from paleoseismologists due to evidence from several large (magnitude 8-9) earthquakes preserved in coastal salt marshes. Stratigraphic records are proving to be useful for learning about the CSZ’s past, and microfossils may provide more answers about large ancient earthquakes. […]

WFS News: Hyolith fossils find place on the tree of life

@WFS,World Fossil Society,Riffin T sajeev,Russel T Sajeev A strange animal that lived on the ocean floor 500 million years ago has been assigned to the tree of life, solving a long-held mystery. The creature has eluded scientific classification since the first fossil was discovered 175 years ago.The extinct hyolith has a cone-shaped shell, tentacles for […]

WFS News: Laser used to unlock mysteries of fossils

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T sajeev A researcher from the University of Cambridge is on the Bonavista Peninsula to get a better understanding of what’s left some of the oldest organisms in the history of life on earth.Paleontologist Emily Mitchell is using a hand-held laser to map thousands of large, complex fossils — dating from about 560 […]

WFS News: Dinosaur-era fossils unearthed in Antarctica

An international research team just made a big fossil discovery in Antarctica, unearthing a haul of remains that date between 67 million and 71 million years old. “We found a lot of really great fossils,” Steve Salisbury, of the University of Queensland School of Biological Sciences, said in a press release. “The rocks the were […]
