He was known for his work on Paleozoic brachiopods and for producing some of the earliest c...

William Gilbert Chaloner was a British paleobotanist and palynologist whose research focused on fossil spores and pollen, particularly from the Carboniferous period. He earned his Ph.D. in 1953 and was elected a Fellow of the Royal Society in 1976, recognizing his contributions to the understanding...

Bothriocidaris is an extinct genus of sea urchin known from Ordovician marine rocks. It represents one of the earliest recognized echinoid lineages and provides evidence for the early diversification of the group during the Paleozoic Era. The genus is studied mainly by paleontologists investigating...

David J. Siveter is a British paleontologist and professor at the University of Leicester whose research focuses on fossil arthropods, particularly ostracods. He is known for his work on exceptionally preserved Silurian fossils from the Herefordshire Lagerstätte in England, which preserve soft-body...

Kaspar Maria von Sternberg was a Bohemian theologian, botanist, and geologist who is widely regarded as one of the founders of modern paleobotany. Born in 1761, he dedicated much of his career to the study of fossil plants, culminating in his seminal work, Flora der Vorwelt, which began publication...

Derek Siveter is a British paleontologist whose research focuses on Paleozoic invertebrates, particularly fossil arthropods and ostracods. He is closely associated with studies of the Silurian Herefordshire Lagerstatte in England, where animals are preserved three-dimensionally in carbonate concreti...

Cladoselache is an extinct genus of shark-like cartilaginous fish from the Late Devonian, known especially from well-preserved fossils found in Ohio. It had a streamlined body, paired fins, multiple gill slits, and two dorsal fins, but lacked several features characteristic of many later sharks. Pre...

Marcello Ruta is an Italian vertebrate paleontologist whose research focuses on the origin, evolution, and relationships of early tetrapods. His work uses comparative anatomy and phylogenetic analysis to investigate Paleozoic vertebrates, including forms relevant to the transition from aquatic sarco...

Archaeocidaris is an extinct genus of echinoids, or sea urchins, known from the Late Devonian through the Late Permian of the Paleozoic era. Fossil material has been reported from Africa, Europe, and North America, and specimens are often incomplete because sea-urchin tests disarticulate after death...

Dieter Korn is a German paleontologist affiliated with the Museum für Naturkunde in Berlin, specializing in Paleozoic ammonoids. His research focuses on the morphology, evolution, and biostratigraphy of these extinct marine invertebrates, whose distinct shells serve as primary index fossils for dati...

Otto Jaekel was a German paleontologist whose research significantly advanced the understanding of fossil fishes and echinoderms, particularly crinoids.
