In the summer of 2015, Brian Engh and I stopped at the Copper Ridge dinosaur trackway on our way back from the field. The Copper Ridge site is 23 miles north of Moab, off US Highway 191. You can find a map, directions, and some basic information about the site in this brochure. The BLM has done a great job of making this and other Moab-area dinosaur trackways accessible to the public, with well-tended trails and nice interpretive signage.

Building on the pioneering work of Karbek (2002), Darren Naish (circa 2004) conceived a theory of sauropod locomotion that has not been as widely accepted as he might have hoped. Sadly, other projects captured Naish’s attention, and his interest in writing up his theory waned.

Building on the pioneering work of Myhrvold and Currie (1997), Darren Naish (circa 2003) conceived a theory of sauropod defence that has not been as widely accepted as he might have hoped. Sadly, other projects captured Naish’s attention, and his interest in writing up his theory waned.

I’d hoped that we’d see a flood of BRONTOSMASH-themed artwork, but that’s not quite happened. We’ve seen a trickle, though, and that’s still exciting. Here are the ones I know about. If anyone knows of more, please let me know and I will update this post.

I imagine that by now, everyone who reads this blog is familiar with Mark Witton’s painting of a giant azhdarchid pterosaur alongside a big giraffe.

Here’s the last post (at least for now) in the Fighting Apatosaur Art series — and we’re back to Brian Engh, who we started with. Early in the process of putting together artwork to illustrate our apatosaur neck combat hypothesis, Brian tried out a whole bunch of outlandish concepts. Here are two that he showed us, but which were too speculative to push forward with.

If we accept that the distinctive ventral projections of the gigantic and ventrally displaced cervical ribs of apatosaurs were likely the base of some form of soft-tissue rugosity — such as keratinous horns like those of rhinos — then does it follow that those necks were used in combat as we suggested? Maybe, maybe not. As scientists, we are always open to other hypotheses.
