@WFS,World Fossil Society,Riffin T sajeev,Russel T Sajeev Dry season limnological conditions and basin geology exhibit complex relationships with δ13C and δ15N of carbon sources in four Neotropical floodplains Abstract Studies in freshwater ecosystems are seeking to improve understanding of carbon flow in food webs and stable isotopes have been influential in this work. However, variation […]

WFS News: Ancient submerged Aboriginal archaeological sites
@WFS,World Fossil Society,Riffin T Sajeev,Russel T sajeev Ancient submerged Aboriginal archaeological sites await underwater rediscovery off the coast of Australia, according to a study published July 1, 2020 in the open-access journal PLOS ONE by Jonathan Benjamin of Flinders University, Adelaide, Australia and colleagues. At the end of the Ice Age, sea level was much lower than […]
WFS News: Oldest Green Algae Fossil
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A newly discovered fossil species of green algae indicates that photosynthesis originated in plants at least 1 billion years ago, paleobiologists reported in Nature Ecology & Evolution yesterday (February 24). The discovery of Proterocladus antiquus helps pinpoint what has been a very broad estimation of when the chlorophyte group of green algae, the relatives […]
WFS News: The Permian-Triassic extinction was directly responsible for disrupting ocean chemistry
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A new study shows for the first time that the collapse of terrestrial ecosystems during Earth’s most deadly mass extinction event was directly responsible for disrupting ocean chemistry. The international study, led by the University of Leeds, highlights the importance of understanding the inter-connectedness of ecosystems as our […]
WFS News: Fossil bite marks of Theropod connected with feeding nature
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Bite marks provide direct evidence for trophic interactions and competition in the fossil record. However, variations in paleoecological dynamics, such as trophic relationships, feeding behavior, and food availability, govern the frequency of these traces. Theropod bite marks are particularly rare, suggesting that members of this clade might not […]
WFS News: The last known freshwater coelacanths
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The last known freshwater coelacanths: New Late Cretaceous mawsoniid remains (Osteichthyes: Actinistia) from Southern France Abstract Coelacanths are iconic fishes represented today by a single marine genus. The group was a little bit more diversified in the Mesozoic, with representatives in marine and continental environments in the Late […]
WFS News: Trackway evidence for large bipedal crocodylomorphs from the Cretaceous of Korea
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Trackway evidence for large bipedal crocodylomorphs from the Cretaceous of Korea Kyung Soo Kim, Martin G. Lockley, Jong Deock Lim, Seul Mi Bae & Anthony Romilio Scientific Reports volume 10, Article number: 8680 (2020) Abstract Large well-preserved crocodylomorph tracks from the Lower Cretaceous (? Aptian) Jinju Formation of South Korea, represent the well-known crocodylomorph ichnogenus Batrachopus. The […]
WFS News: First Fossil Frog
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev First fossil frog from Antarctica: implications for Eocene high latitude climate conditions and Gondwanan cosmopolitanism of Australobatrachia Cenozoic ectothermic continental tetrapods (amphibians and reptiles) have not been documented previously from Antarctica, in contrast to all other continents. Here we report a fossil ilium and an ornamented skull bone […]
WFS News: Ectoparasitism and infections in the exoskeletons of large fossil cingulates
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Ectoparasitism and infections in the exoskeletons of large fossil cingulates Studies on paleopathological alterations in fossil vertebrates, including damages caused by infections and ectoparasites, are important because they are potential sources of paleoecological information. Analyzing exoskeleton material (isolated osteoderms, carapace and caudal tube fragments) from fossil cingulates of the […]
WFS News: First tapejarid pterosaur from the Wessex Formation
@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev First tapejarid pterosaur from the Wessex Formation (Wealden Group: Lower Cretaceous, Barremian) of the United Kingdom An isolated, partial premaxilla from the Lower Cretaceous (Barremian) Wessex Formation of Yaverland, Isle of Wight, UK is identified as pterosaurian on account of its overall morphology and thin bone walls. It is […]
