Arthropod appendages are specialized for diverse roles including feeding, walking, and mating. Fossils from the Cambrian period (539 to 487 million years...
Paleontologists have analyzed the fossilized features of the brain and central nervous system of Mollisonia symmetrica, an extinct animal that lived in...
Trilobites were a diverse group of ancient marine arthropods. Many trilobites lived on the seafloor but some occupied open water. New research has resolved...

Paleontologists have described the oldest known member of Haidomyrmecinae — an extinct subfamily of ants that only lived during the Cretaceous period...
A paleontologist at the University of Leicester has described a new genus and species of enigmatic multisegmented arthropod using a fossilized specimen...
Paleontologists have described a new genus and species of extinct scorpion from the Early Cretaceous Yixian Formation of China.
Jeholia longchengi is the...
The new isopod species has been named Bathynomus vaderi after the most famous Sith Lord in the Star Wars movie series, Darth Vader, whose helmet resembles...
A newly-described genus and species of trilobite is a unique example of an animal changing the form and apparent function of one of its morphological features...
A new species of megacheiran arthropod from the Ordovician period, preserved in 3D by pyrite (commonly known as fool’s gold), has been discovered by...
Based on multiple analytical techniques applied to well-preserved soft-bodied specimens of two trilobite species, the Late Ordovician species Triarthrus...
Tardigrades are a diverse group of microscopic invertebrates widely known for their extreme survival capabilities. Molecular clocks suggest that tardigrades...
Named Youti yuanshi, the newly-identified euarthropod species fills an important gap in our understanding of how the arthropod body plan originated and...
Sea scorpions (eurypterids), extinct giant aquatic arthropods, were apex predators. New research suggests that early species of the scorpion-like carcinosomatoid...
The evolution of the first animals on land, 500 million years ago, has been revealed. The ancestors of millipedes, called euthycarcinoids, evolved in warm...
Mandibulates are an example of evolutionary success, representing over half of all current species on Earth. Today, mandibulates are everywhere: from sea-dwelling...
Paleontologists have unearthed a well-preserved fossil assemblage of Cambrian trilobites in the High Atlas of Morocco. The 510-million-year-old specimens...
Euchelicerata is a large group of arthropods comprising horseshoe crabs, scorpions, spiders, mites and ticks, as well as the extinct sea scorpions and...
In a new paper in the journal Nature Ecology & Evolution, paleontologists described the diversity of the Cabrières Biota, a new Early Ordovician site...
