Sharks of West Fife with Dr Katie Strang
21st October 2020
The chondrichtyans (sharks) are a primitive and highly successful group of fishes, with a skeleton consisting entirely of cartilage. It has been generally accepted that the Chondrichthyes can be divided into two subclasses; Elasmobranchii (sharks, skates, and rays) and Holocephali (chimaeras). In my previous talk I touched briefly on the ‘Golden Age of Sharks’, and also the controversy around Shark taxonomy. Despite shark teeth being among the most abundant of vertebrate fossils, a lot of what we know about their morphology and lifestyle is derived only from these isolated teeth! In this next talk I will look in more detail at the rapid radiation of Chondrichthyans during the early Carboniferous, and also the types of shark teeth we find in Fife – and how we can use the shape of these teeth to help deduce what type of shark it came from, and also how these sharks lived, and what they ate.
