WFS News: ROM mapping of ligamentous constraints on avian hip mobility: implications for extinct ornithodirans

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev ROM mapping of ligamentous constraints on avian hip mobility: implications for extinct ornithodirans Armita R. Manafzadeh, Kevin Padian Studies of soft tissue effects on joint mobility in extant animals can help to constrain hypotheses about joint mobility in extinct animals. However, joint mobility must be considered in three dimensions […]

WFS News: Super-continental split likely occurred more recently than scientists previously thought?

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A nearly 130-million-year-old fossilized skull found in Utah is an Earth-shattering discovery in one respect. The small fossil is evidence that the super-continental split likely occurred more recently than scientists previously thought and that a group of reptile-like mammals that bridge the reptile and mammal transition experienced an […]

WFS News: Globally discordant Isocrinida (Crinoidea) migration confirms asynchronous Marine Mesozoic Revolution

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev A new study of marine fossils from Antarctica, Australia, New Zealand and South America reveals that one of the greatest changes to the evolution of life in our oceans occurred more recently in the Southern Hemisphere than previously thought. The results are published today (17 May 2018) in […]

WFS News: An early Cambrian greenhouse climate

@WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev An early Cambrian greenhouse climate Thomas W. Hearing et.al, Science Advances  09 May 2018:Vol. 4, no. 5, eaar5690,DOI: 10.1126/sciadv.aar5690 The oceans of the early Cambrian (~541 to 509 million years ago) were the setting for a marked diversification of animal life. However, sea temperatures—a key component of the early Cambrian marine […]

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 […]
