In late August, Team TW:eed members were in Liverpool for the annual Symposium of Vertebrate Palaeontology and Comparative Anatomy. Dr Tim Smithson reports.

Jenny Clack presented an analysis of the extraordinary diversity of tetrapods found in the early Carboniferous of the Scottish Borders. Some of these appear to be closely related to Devonian forms while others may be much closer to the radiation of crown group Amphibia and Amniota. This is consistent with the results of recent molecular studies which suggest that the split of extant tetrapods into amphibians, the frogs, newts and cecilians, and amniotes, the reptiles, birds and mammals, occurred in the early Carboniferous. Tim Smithson presented a talk on the fossil lungfish we have been finding in the Borders. Like the tetrapods, these show great diversity. This may in part be due to paedomorphosis, the retention by adults of traits previously only seen in young, and allowed the lungfish that survived the end-Devonian extinction event to radiate quickly.

At some meetings the poster sessions can be less well attended than the conference presentations. This was not the case in Liverpool. The organisers had stolen an idea from the experimental biologists and provided the poster presenters with the opportunity to give a lightening talk of no more than 5 minutes on their work. This generated a lot interest and as a result the poster session was very lively and well supported.
Each year the symposium holds an auction to raise money for the Jones-Fenleigh Fund which assists students with travel costs to the meeting. This year it was held in the chapel of the old Infirmary. Jeff Liston, the auctioneer, deserves a very special mention for pushing up the bidding and encouraging us to part with more funds than we had intended.

The meeting concluded with a Conference Dinner held in the Victoria Gallery Museum, another Waterhouse masterpiece, and provided the delegates with an opportunity to thank and congratulate the organisers for an excellent symposium.
