One of the most effective movies I've seen in recent years is the 2007 science fiction siege thriller, The Mist, which isn't to be confused with the considerably more forgettable eighties pirate horror outing, The Fog (which has one of the most long-winded and least suspenseful trailers ever). Like all good stories, the plot of The Mist is dead simple, with a mysterious, creature-filled
One of the best things about The Mist is that Frank Darabont, it's director, knew exactly what to do with his monsters, in that he shows as little of them as possible. Instead, most species (and there are many) are glimpsed in silhouette at the far reaches of the
The handling of the creatures in The Mist got me thinking about how bizarre, and perhaps how terrifying, the silhouettes of barely-glimpsed creatures in the Mesozoic may have looked on misty, drizzly days. It's not hard to think of a number of Mesozoic animals that would look downright weird when glimpsed through thick fog, but the outlandish proportions of giant azhdarchid pterosaurs, with their long necks and limbs, oversize heads and small bodies, make them unlikely animals at the best of times and truly strange when only seen in outline. The lightweight frames and long limbs of these animals would probably make them lithe and quick over land, and it's not hard to imagine these enormous carnivores giving many Mesozoic animals the hebbie-jebbies as they stalked silently across Cretaceous landscapes. And not just little animals, either: prey of human dimensions may also have been alarmed by a stealthy, fog-strewn azhdarchid.
With this in mind, I've been slowly adding to the painting above for the last few weeks in a very piecemeal, 5-minute burst fashion. It's a deliberately basic image with a limited colour palate and detail, which came from both a desire to attempt something a bit different with my art and enhance the dreary atmosphere. The intention was to make the pterosaur in the background looming and menacing, all but invisible in the dismal weather save for its treetop-scraping silhouette. The small azhdarchid in the foreground, who's giving its big relative an understandably wide berth, serves to add scale, as does the rotting log in the foreground. The taxa here are not meant to be any azhdarchids in particular, but this scene could take place in several places around the Late Cretaceous world. As pointed out by Matyas Vremir et al. (2013), several azhdarchid-bearing deposits yield azhdarchid species of vastly contrasting size, suggesting giants and diminutive species frequently lived alongside one another (see summary image, below, of cohabiting azhdarchids of distinct size, from Vremir et al. , featuring Ron Blakey's fantastic latest Cretaceous palaeomap (Colorado Plateau Geosystems, Inc.), and my handiwork. The image features a new skull reconstruction of Quetzalcoatlus sp., which offers a sneaky peak into some of the imagery used in my book). The scant record we have of these cohabiting species indicates that at least some bore distinct jaw and skull proportions, suggesting different dietary preferences and habits which would prevent them stepping on each other's ecological toes.
