https://doi.org/10.1017/pab.2024.33 Since the 1980s Precambrian palaeontologists believed that early eukaryotes (Domain: Eukarya, microorganisms with a membrane bound nucleus) underwent a dramatic diversification in the Tonian Period (1000-720Ma).…
https://doi.org/10.1017/pab.2025.4 From its revolutionary beginnings in 1975, and an aim to marry biology and palaeontology to answer key evolutionary questions, Paleobiology continues to put innovative fossil and evolution research at its forefront.…
The Brandon Bridge Formation Lagerstätte (site of exceptional fossil preservation) also known as the Waukesha Biota, from Wisconsin, is noteworthy for being one of the best sources of soft-bodied early Silurian fossils.…
William I. Ausich and Mark A. Wilson The Mississippian is recognized as the “Age of Crinoids” with well-known crinoid-bearing deposits worldwide from many ancient depositional environments.…
Palaeontologists have known the fossil rich laminated platy limestones from Kozja dnina (Slovenia) since the beginning of the 20th century. Locality of Kozja dnina is situated in the Vrata valley in the north-eastern part of the Julian Alps.
Trilobites- extinct marine arthropods that roamed the world’s oceans from about 520 million years ago until they went extinct 250 million years ago, at the end of the Permian period – may have grown in a similar fashion and reached ages that match those of extant crustaceans, a new study has found.…
The digit-like branches of Codium, or Dead Man’s Fingers, are a common sight in modern day salt-water bays and lagoons, particularly in areas impacted by fertilizer-rich runoff.…
Past extinction events are key to understanding how modern life will respond to climate change. For ecologists who study communities of interacting organisms, the fossil record holds a wealth of information about how different species react to environmental perturbations, but with a major drawback — it only captures species with bones and shells.
Perhaps no Cambrian invertebrate can claim greater public enthusiasm than Anomalocaris. Not only is it bizarre looking – the story of its discovery, being pieced together from fragments thought to belong to different animals, is uniquely compelling.…
With a total length of up to 5.5m, the tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide.…
Ricinuleids are cryptic, slow-moving arachnids that live under bark, in leaf litter, and in caves in tropical and subtropical areas of the world: Central and South America and West Africa.…
In popular science horses are considered to be the archetype for demonstrating evolution within a time-stratigraphic framework. From small species, horses evolved into the large forms we know today, symbols of power and freedom.…
Mayflies, present in many modern freshwater streams, are often known by their mass hatches in which large numbers gain wings and fly in the air for as little as one day to procreate before dying.…
Extinct dinosaurs are popular subjects in many CGI-animated movies, documentaries and TV shows, but how they are portrayed as living, breathing animals often depends on a lot of guesswork.…
For about thirty million years in the Late Cretaceous, a shallow salty seaway flooded the interior of North America. This separated eastern and western North America into different landmasses.…
There are no crocodilians in Europe, which is good for the safety of those of us who like to peacefully fish or swim in lakes and rivers, but it is somewhat sad for those who prize biodiversity or simply like these fascinating predators.…
Modern day crustaceans, including lobster, shrimp, crayfish, and crabs, are perhaps most familiar from our dinner plates. They, along with less familiar forms such as isopods (your garden pillbugs), belong to the huge living group Eumalacostraca, which includes some tens of thousands of species.…
The Early Jurassic meat-eating dinosaur Dilophosaurus wetherilli is a common figure of many dinosaur movies, books, art, and toys. The distinctive two crests on its head, for which Dilophosaurus owes its name, are unique among dinosaurs and make the animal fascinating to the fossil enthusiast and paleontologist alike.…
The mass extinctions at the end of the Ordovician took out up to 60% of marine genera – the second-most devastating extinction event of the Phanerozoic and the end of the Great Ordovician Biodiversification Event (GOBE).…
Just as humans and squirrels are part of the larger group called mammals, mammals are part of a larger group of animals called synapsids.…
The duck-billed hadrosaurs walked the Earth over 90-million years ago and were one of the most successful groups of dinosaurs. But why were these 2-3 tonne giants so successful?…
Studying how biodiversity on our planet has developed through time and how it reacted to environmental changes would be relatively straight-forward if we could time-travel, as ecologists.…
Upper jaws of a new dinosaur from Victoria, Australia, give fresh insight into the diversity of small herbivorous dinosaurs that once inhabited the ancient Australian-Antarctic rift valley 125 million years ago A new, wallaby-sized herbivorous dinosaur has been identified from five fossilized upper jaws in 125 million year old rocks from the Cretaceous period of Victoria, southeastern Australia.…
Freshwater shark lived in South Dakota, had teeth shaped like “Galaga” spaceships SUE the T. rex is the most famous fossil from the Hell Creek Formation of South Dakota—the most complete skeleton ever discovered of the world’s most popular dinosaur.…
Biodiversity hotspots and gradients are a striking feature across the globe today. While the Latitudinal Diversity Gradient is the best known of these biodiversity patterns, strong gradients in species richness also exist in relation to topography and habitat heterogeneity.…
About 10,000 years ago, in the last moments of the Pleistocene epoch, an extinction of large mammals, or megafauna, occurred. These included the woolly mammoths, mastodons, saber-tooth tigers, giant ground sloths, and enormous woolly bears, all North American inhabitants of the last major ice age.…
A new special issue from the Journal of Paleontology, brings together a collection of 17 papers focused on different aspects of echinoderm paleobiology. Author David F. Wright discusses his article 'Bayesian estimation of fossil phylogenies and the evolution of early to middle Paleozoic crinoids (Echinodermata)'.
A new special issue of the Journal of Paleontology, published on 12th June 2017, brings together a collection of 17 papers focused on different aspects of echinoderm paleobiology.
University of Florida researchers are taking down the Plexiglas walls between museum collections and K-12 classrooms with an educational program that uses 3-D printed fossils and hands-on lessons to spark young learners’ interest in science, technology, engineering and math. The researchers published an assessment of their pilot lesson plan in “Paleontological Society Special Publications” The study '3-D Fossils for K-12 Education: A Case Example Using the Giant Extinct Sharkcarcharocles Megalodon'
A paleontologist at the Canadian Museum of Nature is countering decades of studies that assert that some dinosaurs can be identified as male or female based on the shapes and sizes of their bones.
A new study in Paleobiology has compared the diet of a variety of Australian megafaunal herbivores from the period when they were widespread (350,000 to 570,000 years ago) to a period when they were in decline (30,000 to 40,000 years ago) by studying their fossil teeth. The analysis suggests that climate change had a significant impact on their diets and may well have been a primary factor in their extinction.
How long will humankind survive? Besides the fact that we have been able to eliminate ourselves with nuclear weapons for decades, even without a third world war, the challenge to take care of the resources of our planet remains; we need to use them in a way that our children and their children can have a place on Earth as well.

More and more research is finding inflammation as a potential contributing factor towards to the development of various mental illnesses. A systematic review was conducted to determine the association between parasitic infection and mental illnesses in various African populations. Two parasite groups were evaluated; helminths and protozoans, and four mental illness classifications; depressive disorders, anxiety disorders, schizotypal disorders and unspecified mental illnesses.
