@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 […]

June 13th, 2020 Riffin @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 […]

May 31st, 2020 Riffin @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 […]

May 27th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev In 1996, palaeontologists found skeletal remains of a giant shark at the northern coast of Spain, near the city Santander. Here, the coast comprises meter high limestone walls that were deposited during the Cretaceous period, around 85 million years ago, when dinosaurs still roamed the world. Scientists from […]

May 20th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev The newly-discovered dinosaur belongs to Elaphrosaurinae, an enigmatic group of gracile ceratosaurian dinosaurs known from the Late Jurassic period of Africa and Asia, and the early Late Cretaceous period of Argentina. “Elaphrosaurs were strange looking dinosaurs — they ran low to the ground on two legs, with a slender […]

May 17th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev Cassowaries are big flightless birds with blue heads and dinosaur-looking feet; they look like emus that time forgot, and they’re objectively terrifying. They’re also, along with their ostrich and kiwi cousins, part of the bird family that split off from chickens, ducks, and songbirds 100 million years ago. […]

May 8th, 2020 Riffin @WFS,World Fossil Society,Riffin T Sajeev,Russel T Sajeev In evolutionary terms, islands are the stuff of weirdness. It is on islands where animals evolve in isolation, often for millions of years, with different food sources, competitors, predators, and parasites…indeed, different everything compared to mainland species. As a result, they develop into different shapes and sizes and […]
