|A, the plastron of the fossil Romanian turtle Kallokibotion magnificum, compared with B, the alleged holotype 'cranial crest' of 'Thalassodromeus sebesensis'. For further details, see yesterday's post.|
This post isn't really about that, though: it's about correcting a mistruth in Codrea and Grellet-Tinner's response. Their comment shows little decorum or professionalism, attempting to undermine our response with ad hominem potshots at some authors of Dyke et al. (2014), including criticism of their editorial skills and the taxonomic confusion surrounding specimens described by the authors. Moreover, they criticise us for not examining the specimen, UBB ODA-28, before publishing our response. They state that:
"...UBB ODA-28 is housed in an official and recognized Romanian institution, thus available for examinations to anyone interested. This includes Dyke’s July 2nd 2014 written request to examine UBB ODA-28, which was immediately granted, although, Dyke went on writing its hasty comment without examining UBB ODA-28."
Codrea and Grellet-Tinner, 2014, p. 3-4 (my emphasis)
Well, this isn't really true. Some of it is: Gareth Dyke did write to ask for permission to look at the specimen this year - specifically between July and September - but 'immediate' access was not granted. Rather, eventual access was promised following on-going studies, including CT scanning of the specimen, the dates of which was not disclosed. This is not, as Codrea and Grellet-Tinner describe, 'immediately' granting access, but nebulously promising access at an undetermined future date.
This may not seem like a big deal, but our integrity is being questioned for having not seen the specimen, so we - the authors of Dyke et al. (2014) - think the record should be set straight. There's no doubt that examining specimens is the way forward in any research. But it was clear from Gareth's correspondence that accessing UBB ODA-28 was going to be difficult for the immediate future, and all the while the science behind 'T. sebesensis' remained extremely problematic and in need of swift rebuttal. Why? In short: none of us concerned with pterosaurs or European palaeontology want to deal with this outrageous, nonsensical claim in future publications. Hence, we fell back on using the published accounts of UBB ODA-28 to construct an argument against the pterosaur identification. Given that our authorship team has collectively amassed thousands of hours examining actual thalassodromid pterosaurs, as well as turtle plastrons, and how obvious the turtle affinities of the specimen are, this method seemed more than sufficient for the task at hand. Despite allegations from Codrea and Grellet-Tinner, these were not the actions of a team hastily assembling a rebuttal, but a collective of experienced individuals succinctly calling out obvious flaws in bad science.
So there we go: that's our side of that mistruth. Hopefully, that's the last we'll hear of 'T. sebesensis' around these parts, for there are much more interesting and exciting things to cover: palaeoart guides, Triassic fuzzy saltating xerocoles, dinosaur fat humps... all coming soon.
