The Mesozoic era, meaning “middle life”, is a division of earth’s history spanning from around 252 to 66 million years ago. It is subdivided into the Triassic, Jurassic and Cretaceous periods. The beginning of the Mesozoic is characterised by a long phase of recovery following the end Permian mass extinction. The end of the Mesozoic is marked by the Cretaceous/Paleogene extinction event which wiped out the dinosaurs among other groups.

Living ostracods

Episode 35: Ostracods

Published on October 16th, 2014 | by Dave Marshall

Ostracods are tiny crustaceans (relatives of shrimps, crabs and water-fleas), distinguished by having a shell that is easily fossilised. As microfossils, by virtue of a long and rich fossil record, ostracods are extremely useful for determining [&hellip... Read More

Published on June 1st, 2014 | by Dave Marshall

One of the longest-ranging and outwardly primitive-looking groups of animals on the planet are the Medusozoa. In consisting of around 95% water, it may be surprising to know that there is a fossil record of jellyfish, [&hellip... Read More

Episode 14: Trace Fossils

Published on April 1st, 2013 | by Dave Marshall

Ichnology is the study of trace fossils (also termed ichnofossils). Opposed to body fossils, the physical remains of an organism, trace fossils are the fossilised interactions between an organism and the substrate/sediment and include such things [&hellip... Read More

Episode 8: Mesozoic Vertebrate Ecology

Published on December 15th, 2012 | by Dave Marshall

The Mesozoic Era saw the spectacular rise and fall of many groups, particularly in terrestrial vertebrates. These include birds, squamates, crocodiles, and pterosaurs, who wove a complex tapestry of evolution through the 185 million years of [&hellip... Read More
