“A thrilling bit of taxidermy”

Museums, it seems, are in a constant struggle to reinvent themselves, updating and enhancing their displays to reflect both the current understanding of particular topics as well as contemporary views on how best to engage their public. On the whole, I happen to feel that these changes are generally beneficial to both the institutions and their audiences. Still, there is an undeniable appeal to the idea of a timeless museum, where one can share the experience of a particular specimen or diorama or exhibit with visitors from generations past or, one hopes, those yet to come.

I was reminded of this during a recent visit to the Carnegie Museum of Natural History, which is now only days away from unveiling the first part of its extensively remodeled dinosaur halls. While there, I was pleased to see that an old taxidermy mount was still on display in its upper floors, one that had caught my attention when I first came across it some 15 years ago, and, as I subsequently learned, had made an impression on a young Charles Knight when he saw it at the American Museum more than a century prior.

From Charles R. Knight: Autobiography of an Artist (published by G.T. Labs):

“I particularly remember one striking group (our only example) of an Arab camel rider being attacked by a lion. Perhaps other men my age will recall this dramatic piece which for some reason I never clearly understood was in later years given to the Carnegie Museum in Pittsburgh. I always regretted its going as it certainly was a thrilling bit of taxidermy, and only an artist could have done it. The man of course was wax, but his expression as he sat astride the camel’s neck to escape the claws of the big cat was well worth seeing. A dead lioness with a little red paint for blood lay at the feet of the camel, and this artificial gore was, I fear, the cause of it being sent away, as it was thought too sensational for a staid institution like our Museum.”

New Carnival: Linnaeus’ Legacy

8:22 am

Over at Catalogue of Organisms, Christopher Taylor has celebrated his 100th post in high style: by instituting a new blog carnival christened Linnaeus’ Legacy.

As Christopher puts it, “…this will be a monthly review of recent posts on the subject of biodiversity past and present, the study of said biodiversity and the questions of how to understand, describe and communicate about it. Posts will be accepted on all aspects of taxonomy and systematics, from the esoteric (species concepts, classificatory principles) to the pragmatic (new discoveries in the world of systematics) to the didactic (communicating about taxonomy).”

If the explanation seems like a mouthful, don’t worry. In the end it translates into a great collection of posts to browse through each month. Stop by the first edition and see for yourself!

More Phyto-sketches

Phytosaur skull

A couple more sketches from my ongoing studies of phytosaurs. The one above is from a four foot long skull of the big pseudopalatine Redondasuchus (the front half and teeth are reconstructed, but they show nicely the heterodonty discussed in the last post). Below is a quick smudgy sketch of a Pseudopalatus cruising along in a “high-walk.” Overall I think the armor looks a touch more convincing than that portrayed in the full-body sketch of Parasuchus from last time:

A Trio of Temnospondyls

11:32 pm

About a week ago, the Geological Society of America announced the discovery of an unique trace fossil from the Mississippian-age Mauch Chunk Formation in eastern Pennsylvania, which preserved the impressions of three temnospondyl amphibians that laid in this Mississippian mud some 330-million years ago.

Spencer G. Lucas (New Mexico Museum of Natural History and Science), David L. Fillmore and Edward L. Simpson (both from Kutztown University in northeastern Pennsylvania) presented this unique fossil at the 2007 GSA Annual Meeting. Spencer asked me to draw up a reconstruction showing the temnospondyls whose imprints were preserved in the fossil, which I took particular pride in, since I, too, happen to be a tetrapod from eastern Pennsylvania. My take on the temnospondyl trio is shown below:

Temnospondyls
My take on the temnospondyl trio. The impressions in the fossil slab are raised, so when you look at it you are
actually seeing the animals’ imprints from underneath; in this top-down view their positions are flipped horizontally.

This drawing was included in the press release but, due to a miscommunication, it was not initially credited. Oddly enough, I was back in northeast PA visiting family when the release went out, so I didn’t realize it until I returned to New Mexico yesterday. I’m happy to say that the oversight has since been corrected on the GSA page.

But beyond my personal stake in the story, the fossil really is quite spectacular. The imprints seem to show your standard temnospondyl four-fingered hand, and what looks like a crease of skin down the midline of their bellies, with no apparent sign of scales. As Lucas et al. note in their abstract, the fact that the three were preserved together indicates some sort of gregarious activity, and the tastefully phrased “head-to-tail overlap” shown in two of the impressions is reminiscent of the courtship behaviors of some modern amphibians.
