This week I travelled to Tartu in Estonia to present our work at the 8th European Ostracod Meeting.
Ostracods are found with tetrapods, fish, bivalves, scorpions and many other fossils in the Ballagan Formation of the early Carboniferous. They are 1 mm sized bivalve shells that belong to arthropod crustaceans. They are especially interesting in their ability to rapidly colonise environments and cope with a huge range of salinity. Want to know more about ostracods? Check out this great new site ostracoda.net.
Ostracods and bivalves are the most common invertebrate fossils found in the Ballagan Formation. I was presenting our work on the links between actinopterygian fish, bivalves and ostracods, that occur together very commonly. I discussed aspects such as how they may have survived in temporary water-bodies and how bivalves could have been transported. Due to our micropalaeontology and vertebrate palaeontology research (especially all the fish teeth discoveries) we are now able to piece together what Carboniferous food webs might have looked like. It was fantastic to get some feedback on this work and speak to some experts in living and fossil ostracods.
