Sharks first evolved almost 200 million years before the dinosaurs and we’re still learning more about species past and present. Emma Bernard, Curator of Fossil Fish, joined Alistair Hendry to show off some of the Museum’s shark specimens, and to answer your questions. Find out just how huge a Megalodon tooth is, discover strange shark species and see some incredible fossil specimens including one where cartilaginous soft tissue has been preserved.
What do an Iguanodon’s thumb spike, an ichthyosaur paddle and a shark fin spine all have in common? Well these are just some of the specimens we’ve digitised as part of the museum’s eMesozoic project, headed by Fossil Mammal Curator Dr Pip Brewer.
For the past eight months myself and two other eMesozoic digitisers, Lyndsey Douglas and David Godfrey, have been busy in the palaeontology department mass imaging British Mesozoic vertebrates for the first time.
When I first came to the Museum I dreamt that one day someone would bring something in for identification that I would recognise to be a really important find. The contents of a consultancy sample back in 2005 helped to make my wish come true. This post tells of the discovery and subsequent publication of a significant species of early fossil fish from Oman that provides information on the origins and evolution of life on our planet, one of the main focus areas of Museum science.
Very occasionally I get consultancy rock samples sent to me for dissolving to find microfossils. This is so that we can provide the age for a rock formation or details about fossil environments or climate. And so it was that Alan Heward, then of Petroleum Development Oman (PDO), sent me a sample in 2005 for analysis to try to find age diagnostic conodonts. Conodonts are extinct phosphatic microfossils that look like teeth and are used extensively for dating rocks that are roughly 500-205 million years old.
