Everybody(*) knows that the turiasaurian sauropod Moabosaurus has bifurcated cervical ribs: it was all anyone was talking about back when that animal was described (Britt et al. 2017). We’ve featured the best rib here before, and here it is again: {.alignnone .size-full .wp-image-21111 loading=“lazy” attachment-id=“21111”

I haven’t blogged about blogging in a while. Maybe because blogging already feels distinctly old-fashioned in the broader culture. A lot of the active discussion migrated away a long time ago, to Facebook and Twitter, and then to other social media outlets as each one in turn goes over the enshittification event horizon.

New paper out today in PeerJ: Lei R, Tschopp E, Hendrickx C, Wedel MJ, Norell M, Hone DWE. 2023. Bite and tooth marks on sauropod dinosaurs from the Morrison Formation. PeerJ 11:e16327 http://doi.org/10.7717/peerj.16327 This one had a long gestation.

Back in 2013, we showed you Bob Nicholls’ beautiful sketch “The Giant & Company”, featuring a giant Apatosaurus with a shaggy beard running along its neck.

I’ve been away for two weeks with Fiona in Kefalonia, one of the Greek islands.

Utahraptor is a “giant” dromaeosaurid from Utah, described by Kirkland et al. (1993). Famously, its existence was part of the reason that the people making Jurassic Park felt at liberty to make their “Velociraptor” individuals not only much bigger than the turkey-sized Velociraptor proper, but also than than sheep-sized Deinonychus.

Inter-source correlograms yield coherent signals upon careful consideration of source mechanisms and source-receiver geometry, affording new means of characterizing planetary interiors.

As all good SV-POW! regulars will know, Elmer S. Riggs published the name Brachiosaurus altothorax in a short (but not trival) 1903 paper (Riggs 1903) and followed it up with a proper descriptive monograph (Riggs 1904) that had several useful plates. I’ve never seen a real copy of the latter (or indeed the former), so for the last quarter-century I’ve made do with various low-quality photocopies and scans.

Introduction and benchmarking The convection of the Earth’s mantle is usually modelled as an incompressible process, referred to as the Boussinesq approximation. However, in the Earth’s mantle, the pressure increase associated with depth also increases the density due to self-compression (King et al. 2010). In some applications, this compressibility may be non-negligible and modelling it may be desirable.

How can the global research infrastructure increase understanding of the myriad contributions made to global knowledge by U.S. Federal agencies? How can we use this infrastructure to increase understanding of connections across the U.S. and global research landscape? How can this infrastructure be used to increase completeness, consistency, and connectivity within agency repositories and search tools?
