Patterns in Palaeontology: The development of trilobites

by Lukáš Laibl*1 Introduction: Trilobites are an iconic group of ancient animals, with a fossil record that dates back more than 500 million years and consists of some 17,000 species. These extinct arthropods are characterized by a hard, mineralized exoskeleton, which greatly enhances their chances of being preserved as fossils. The exoskeleton is thought to have […]

Education and Outreach: The history of dinosaur palaeoart

by Szymon Górnicki*1 Introduction: Non-avian dinosaurs are iconic animals that dominated life on land for 170 million years during the Mesozoic era, and have captured the imagination of scientists and non-scientists alike for as long as we have known about them. As a result, dinosaurs have also dominated palaeoart — artistic representations of past life. Palaeoart […]

Fossil Focus: The Archosaur Respiratory System — Or — Breathing Life into Dinosaurs

by Robert Brocklehurst*1 Introduction and background Dinosaurs fascinate people more than almost any other group of fossil animals, and the general public is interested in many open questions on dinosaur biology. How fast could dinosaurs run? Were they warm blooded? If they had feathers, does that mean they could fly? These questions focus on dinosaur […]

Education and Outreach: Exhibiting the scientific process

by Brittney Stoneburg*1 Introduction: Natural history museums are not just exhibit space: a lot of scientific research is conducted behind the scenes. This is the nature of almost any museum. It is often not logistically or financially possible to exhibit every object, and not every fossil is suitable to go on display. The fossils that […]

Patterns in Palaeontology: Environments of the Cambrian explosion

by Thomas W. Hearing*1 Introduction: Shimmering curtains of sunlight stream down through the waters of a shallow sea that has been advancing landwards for several million years. This transgression has formed wide areas of shallow continental shelf seas. The sea bed teems with life — some of it familiar, some much less so. The oddities […]

Fossil Focus: Hallucigenia and the evolution of animal body plans

by Martin Smith*1 Introduction: Five hundred and fifty million years ago, few (if any) organisms on Earth were much more complex than seaweed. But this would not be the case for long: during a profound evolutionary event dubbed the Cambrian Explosion, natural selection generated the raw material of all the body plans we see in […]

Perspectives: Fossils and the Law — A Summary

by Jack J. Matthews1 Introduction: Geoconservation, also known as Earth Heritage Conservation, is how we protect important examples of Earth’s physical resources. Geological features can be protected for all sorts of reasons, including being important to cultural heritage, geological education and understanding, or the overall aesthetics of an area. A great many designations, management frameworks […]

Fossil Focus: The Ediacaran Biota

by Frances S. Dunn*1 and Alex G. Liu2 Introduction: The Ediacaran period, from 635 million to 541 million years ago, was a time of immense geological and evolutionary change. It witnessed the transition out of an ice-house climate, the break–up of one supercontinent (Rodinia) and the assembly of another (Gondwana), a major meteorite impact (the Acraman […]
