And for included taxa, more than a third (31 of 88) underreported the largest published value by 10% or more. Mehmood et al. sometimes report higher values than TEMNOS - sometimes this is b/c they extrapolated from a reconstruction (I don't do this yet), but some of these values are clearly errors.

Despite claiming to have comprehensively sampled temnospondyls, this study failed to include published data from nearly as many species that met inclusion criteria (graph) as species that were included. Max. skull length of every missed species that was published by 2024 is shown below.

Phylogenetic analysis and qual comparisons suggest Aspidosaurus nests higher in the dissorophid tree than was previously thought on the basis of the (probably) chimeric A. binasser, putting it much closer to the well-known Cacops. Still a lot in flux re: dissorophid phylogeny though (15/n)

Broili's description of the skull is very brief - no sutures or much to go on - but superficially, the Smithsonian specimen looks about as similar to the lost holotype as is possible from 120yo figures and can be readily differentiated from all other dissorophids with skulls (11/n)

This new specimen comprises a nearly complete skull and substantial amounts of postcranial material, including a block of several articulated osteoderms and vertebrae. When I looked at the osteoderms, I immediately recognized them as identical to what Broili had figured for Aspidosaurus chiton (9/n)
July 11, 2025 at 3:48 PM
A number of new taxa were named exclusively on the basis of a single osteoderm, typically not a solid basis for a new taxon, and the genus has an extreme temporal range of over 25myr as a result. Various examples of some holotypes of other species are shown below (6/n)

In 1901, a German paleontologist named Ferdinand Broili visited the U.S. to collect Permian fossils from the classic Texas redbeds with Charles Sternberg. Several years later in 1904, he published a lengthy monograph in which he named a new dissorophid, Aspidosaurus chiton (2/n)

New paper out today in @zoojlinnsoc.bsky.social for #FossilFriday AKA here's-Bryan's-one-paleo-paper-this-year-to-remind-people-I-still-do-paleo-sometimes: a revision of the #Permian #dissorophid #temnospondyl Aspidosaurus chiton based on a new specimen: doi.org/10.1093/zool... (1/n)

And discusses the need for (re)curation, lots of case studies about current/previous systemic metadata issues. Dryad publication years in DataCite all out of sorts right now. Also, I think I discovered a huge screw-up where Figshare assigned the wrong affiliation to thousands of datasets! (5/5)

Also discusses some of the metadata assessments we're doing (i.e. what are we doing with the data once we have them). Examples including identifying mislabeled deposits (e.g. datasets with code+data or just code; licensing) (4/5)

The preprint is mainly designed to explain the gory details of the process, although it does show data for UT Austin specifically, like how many different ways people write "UT Austin" and whether an affiliated researcher is first/last author or not (proxy for how involved they were) (3/5)
July 3, 2025 at 1:35 PM
As I've previously mentioned, I've gotten creative with this and can get datasets with no DOIs that do have affiliations (like NCBI) and datasets with DOIs but no affiliations (like automated Figshare deposits mediated through journal partners)

Created an exhibit @burkemuseum.bsky.social on how 250 million-year-old amphibian fossils from Antarctica inform both our understanding of deep time environments and modern systems as part of my #NSF funded postdoc (seen by >200k visitors)

What personally bugs me as a researcher is how those two harness special issues. As a reviewer, I have terrible exp with special issues - my comments are almost always entirely ignored, editors don't reject or even force revisions. Have seen unanimous reject get pub'd as is

Elias et al. propose a novel rhinesuchid from the Middle-Late Permian of Brazil (what happened to "don't name new taxa in preprints"?) based on a partial skull. It clusters with the one Triassic rhinesuchid, Broomistega, in phylogenetic analyses. [preprint, not accepted] ssrn.com/abstract=491...

Some preprints: @akufner.bsky.social et al. (CC: @calamanderso.bsky.social @paleobadger.bsky.social) provided a taphonomic analysis of a monotaxic metoposaurid bonebed from Wyoming, the 1st documentation of Buettnererpeton bakeri in the Popo Agie Fm. [preprint, not accepted] doi.org/10.1101/2024...
