This is super cool: my friend and lead author on the new saltasaur pneumaticity paper, Tito Aureliano, made a short (~6 min) video about the fieldwork that Aline Ghilardi and Marcelo Fernandes and their team — many of whom are authors on the new paper — have been doing in Brazil, and how it led to the discovery of a new, tiny titanosaur, and how that led to the new paper. It’s in Portuguese, but with English subtitles, just hit the CC button.

Well, this is a very pleasant surprise on the last day of the semester: Tito Aureliano, Aline M. Ghilardi, Bruno A. Navarro, Marcelo A. Fernandes, Fresia Ricardi-Branco, & Mathew J. Wedel. 2021. Exquisite air sac histological traces in a hyperpneumatized nanoid sauropod dinosaur from South America. Scientific Reports 11: 24207.

Free surface in geodynamics simulations Geodynamic simulations increasingly rely on models with a true free surface to investigate questions of tectonic deformation, mantle convection, and coupling of surface processes and lithosphere dynamics. Historically, most mantle convection simulations have been performed with free-slip boundary conditions at the surface.

We are in the early days of documenting output management plans using DataCite metadata so it is an important time to identify and adopt common practices that help realize the exciting goals of machine-actionable DMPs. Common practices will facilitate the creation of interoperable DMPs and the development of tools across the research community that help us all reap the on-going benefits of these plans throughout the research life-cycle.

As I was clearing out some old documents, I stumbled on this form from 2006: This was back when Paul Upchurch’s dissertation, then only 13 years old, contained much that still unpublished in more formal venues, notably the description of what was then “ Pelorosaurus ” becklesii . As a fresh young sauropod researcher I was keen to read this and other parts of what was then almost certainly the most important and comprehensive

Distributed acoustic sensing, or DAS, is a newly developed passive seismic technology that can transform telecommunication fibre-optic cable into linear arrays of ground motion sensors.

Back in June, I saw a series of tweets by sculptor and digital artist Ruadhrí Brennan, showing off the work he’d been doing on sculpting brachiosaurid skulls: Giraffatitan , Brachiosaurus (based on the Felch Quarry skull USNM 5730) and Europasaurus . Impressed, I asked if he would send a Giraffatitan skull, and here it is! You can immediately see two things: one, it’s good.

I plunged headfirst into a commitment to post a picture from my research once a day for 100 days, beginning on the first day of semester two, 2021.
