Plesiosaurs and the repeated invasion of freshwater habitats: late-surviving relicts or evolutionary novelties?

Time to talk about another recently published paper I was involved in: this time, the looooong awaited Journal of Systematic Palaeontology paper ‘A new leptocleidid (Sauropterygia, Plesiosauria) from the Vectis Formation (Early Barremian-early Aptian; Early Cretaceous) of the Isle of Wight and the evolution of Leptocleididae, a controversial clade’ (Benson et al. 2012a). Wow, what [...]Keep reading

But unless you’re a palaeontologist or zoology uber-nerd, you might well not have heard of placodonts, pachypleurosaurs, nothosauroids and pistosaurids – the other lineages that, together with plesiosaurs, form Sauropterygia, a major clade of Mesozoic marine reptiles. Here’s a much-simplified cladogram showing [...]Keep reading

Having just covered Mesozoic marine reptiles, and seeing as I can’t find the time to finish anything more substantial, it seems like a good time to use these wonderful images, passed to me by a correspondent. They clearly show the carcass of a freshly deceased, modern-day marine reptile of Mesozoic style. For those in the [...]Keep reading
Dinosaurs at SVPCA – no Mesozoic non-avialan theropods, thank you very much – and what about those marine reptiles?

In the previous article I penned various of my thoughts on the 59th SVPCA (= Symposium on Vertebrate Palaeontology & Comparative Anatomy), this year held at Lyme Regis in Dorset. You might need to read that previous article to make sense of this one. That first article covered pterosaurs, various non-archosaurs and an assortment of [...]Keep reading
