More sauropod vertebrae/ ceratopsian frill convergence
I was reminded by Mike Taylor's recent post, noting that a Camarasaurus vertebrae seems to have a ceratopsian frill growing out of it, that I had had the exact same thought when I saw 'Max'. Max is a diplodocid (identified as Apatosaurus but I have my doubts) found by the crew at the Saurier Museum in Aathal. However this time the 'frilloid' process is composed of the two postzygapophyses and the perforate interpostzygapophyseal lamina. Incidentally the interpostzyg laminae of most of Max's cervicals are similarly perforate. It is a real feature, not caused by damage - weird huh?
