WFS News: Researchers discover 48-million-year-old lipids in a fossil bird

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev As a rule, soft parts do not withstand the ravages of time; hence, the majority of vertebrate fossils consist only of bones. Under these circumstances, a new discovery from the UNESCO World Heritage Site “Messel Pit” near Darmstadt in Germany comes as an even bigger surprise: a 48-million-year […]

WFS News: Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Researchers from North Carolina State University, Lund University in Sweden and the University of Hyogo in Japan have retrieved original pigment, beta-keratin and muscle proteins from a 54 million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions […]

WFS News:Dinosaur DNA Research: Is the tale wagging the evidence?

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Dinosaurs are a popular topic of study, whether in the public imagination or in scientific research. The scientific community, however, has a dirty little secret regarding the manner in which that research is handled. If dinosaur DNA doesn’t “look like chicken” (or a crocodile), it will most […]

WFS News:Fossil discovery in Tanzania reveals ancient bobcat-sized carnivore

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Paleontologists working in Tanzania have identified a new species of hyaenodont, a type of extinct meat-eating mammal. The study is published today, National Fossil Day, in the journal PLOS ONE and funded by the National Science Foundation (NSF). After the extinction of the non-avian dinosaurs 66 million […]

WFS News: ‘Obscure’ stalked filter feeder lived in Utah some 500 million years ago

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev To the untrained eye, it looks like a flower crudely etched into rock — as if a child had scratched a picture of a bloom. But to the late fossil hunter Lloyd Gunther, the tulip shape he unearthed at Antimony Canyon in northern Utah looked like the remnant […]

WFS News:Dinosaur blood? New research urges caution regarding fossilized soft tissue

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Scientists have conducted experiments to accelerate degradation in keratinous tissues such as feathers, scales and hair in order to simulate the processes that occur over deep time as something becomes a fossil. Their findings demonstrate that previous claims showing the preservation of keratin protein in dinosaur fossils are […]

WFS News: Earliest evidence of reproduction in a complex organism

@ WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Researchers led by the University of Cambridge have found the earliest example of reproduction in a complex organism. Their new study has found that some organisms known as rangeomorphs, which lived 565 million years ago, reproduced by taking a joint approach: they first sent out an ‘advance […]

WFS News: 3-D scanning methods allow an inside look into fossilized feces

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev ┬áCoprolites are fossilized feces that give evidence of an organism’s behavior and often contain food residues, parasite remains and other fossils that provide clues to ancient paleoecological relations. Many of the inclusions in coprolites are delicate and fossilized soft tissues, which in many cases are more likely preserved […]

WFS News: Birgeria americana,Large-mouthed fish was top predator after mass extinction

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The most catastrophic mass extinction on Earth took place about 252 million years ago — at the boundary between the Permian and Triassic geological periods. Up to 90 percent of the marine species of that time were annihilated. Worldwide biodiversity then recovered in several phases throughout a period […]

WFS News: Ponomarenkia belmonthensis,300 MYO beetle

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev He’s Australian, around half a centimetre long, fairly nondescript, 300 million years old, and he’s currently causing astonishment among both entomologists and palaeontologists. The discovery of a beetle from the late Permian period, when even the dinosaurs had not yet appeared on the scene, is throwing a completely […]
