@WFS,World Fossil Society,Riffin T Sajeev, Russel T Sajeev Ankylosaurs could grow up to eight meters in body length and represent a group of herbivorous dinosaurs, also called ‘living fortresses’: Their body was cluttered with bony plates and spikes. Some of their representatives, the ankylosaurids sometimes possessed a club tail, while nodosaurids had elongated spikes on […]

November 29th, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel Sajeev Adaptations of the lower back to bipedalism are frequently discussed but infrequently demonstrated in early fossil hominins. Newly discovered lumbar vertebrae contribute to a near-complete lower back of Malapa Hominin 2 (MH2), offering additional insights into posture and locomotion in Australopithecus sediba. We show that MH2 possessed a lower back […]

November 1st, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Many people hate insects, but the iridescent colors and elegant flying style of dragonflies and damselflies have made them firm favorites worldwide. They have been around in some form for hundreds of millions of years, but the evolutionary history of these relics of prehistoric life has been poorly […]

October 19th, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Amber research by the Oregon State University College of Science has produced the first definite identification of grass in fossilized tree resin from the Baltic region, home to the world’s most well-known amber deposits. The specimen studied by George Poinar Jr., named Eograminis balticus, also represents the first […]

August 31st, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Taytalura alcoberi lived in what is now Argentina during the Late Triassic epoch, approximately 231 million years ago. The ancient reptile was a member of Lepidosauromorpha, a large group that includes squamates (lizards and snakes) and sphenodontians (tuataras). “Lepidosauromorphs and archosauromorphs represent the two main branches of the reptile tree of life […]

August 29th, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev One of the biggest questions in evolution is when and how major groups of animals first evolved. The rise of tetrapods (all limbed vertebrates) from their fish relatives marks one of the most important evolutionary events in the history of life. This “fish-to-tetrapod” transition took place somewhere between […]

August 28th, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A semiaquatic whale that lived 43 million years ago was so fearsome, paleontologists have named it after Anubis, the ancient Egyptian god of death. The newly discovered 10-foot-long (3 meters) species, dubbed Phiomicetus anubis, was a beast; When it was alive more than 43 million years ago, it both walked on […]

WFS News: A billion years missing from geologic record: Where it may have gone.
August 20th, 2021 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The geologic record is exactly that: a record. The strata of rock tell scientists about past environments, much like pages in an encyclopedia. Except this reference book has more pages missing than it has remaining. So geologists are tasked not only with understanding what is there, but also […]
