DUTUITOSAURUS, from the ✨NEW VIDEO: www.youtube.com/watch?v=YULv... ✨ dedicated to Temnospondyls 🐸. It's estimated this one could reach about 3m and was found in Morocco #dutuitosaurus #triassic #paleoart #temnospondyl

#temnovember2024 day 23: Dutuitosaurus
And now for a big #metoposaurid, #Dutuitosaurus, a large acuatic predator from the upper Triassic of north africa, very similar to de european #Metoposaurus

My 25 years of palaeoart chronology...

In 2020 I illustrated LOCKED IN TIME, by @deanrlomax.bsky.social. Here's my "Casualties of the Drought" painting, which depicts hundreds of Dutuitosaurus crammed into a drying pond.

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...
Photographs of skulls of Buettnererpeton bakeri from the Late Triassic of Wyoming in dorsal and ventral views, along with interpretive line drawings. The skulls are a light brown-grey colour, with the typical ornamentation and deeply incised lateral line grooves of metoposaurids. The depicted specimens are nearly complete skulls. One preserves a covering of denticulate plates that would have covered the interpterygoid vacuities in life. Comparison of the relative completeness of skeletons among three metoposaurid bonebeds: Elkins Place (type locality of Buettnererpeton bakeri in Texas), Site XIII (type locality of Dutuitosaurus ouazzoui in Morocco), and the newly described Nobby Knob site in Wyoming. The minimum number of individuals is used to calculate what percent of skeletons are complete with respect to different elements. The large, flat, ornamented elements (clavicle, interclavicle, skull) tend to be best represented, while oddly shaped elements like pelvic girdles, neural arches, and haemal arches, are not necessarily rarer in absolute count but are less-represented in terms of how many would be predicted to occur based on the minimum number of individuals (e.g., there should be dozens of neural arches in one individual compared to one interclavicle per individual).

So is Nobby Knob more of the same or is it different?

It's different! Nobby Knob exhibits more even representation of the skeleton than two other bonebeds analyzed by us and likely than both Lamy and Rotten Hill (although raw count data were not accessible for these two sites).

8/16
A map of the Nobby Knob quarry. The bones are densely packed, and some specimens are articulated, but this is clearer in the individual field jacket maps included in the supplemental material. A rose diagram in the upper right shows no preferred orientation of the long bones in this quarry. Different metrics to show how well represented skeletons are at three sites. Estimates for skeletal content were made based on nearly complete articulated skeletons of Dutuitosaurus figured by Dutuit (1976). The first three panels show our preferred method of normalizing the observed number skeletal elements to the expected number based on minimum number of individuals (1 is complete representation, 0 is absent). Note that Nobby Knob has more complete skeletal representation than the other two sites one of which (Site XIII from Morocco) includes articulated skeletons. We think the counts of Site XIII are biased by photographic plates being selected for slabs showing primarily skulls, so not a comprehensive sample of the whole site. The bottom right panel shows a ternary diagram of Voorhies dispersal groups (VDG) and different schema used to assess temnospondyls. Despites differences in the underlying assumptions for which bones are assigned to dispersal potential groups, the conclusions for each sites are roughly the same i.e. more sorted assemblages trend toward overrepresentation of VDG III.
