Wooster’s Fossils of the Week: Geological Magic Lantern Slides from the 19th Century (Part I)

November 25th, 2016

1-teleosaurus-ichthyosaurus-pentacrinites-ammonites-gryphaea“Wooster’s Fossil of the Week” is not always about actual fossils, but our topics are each paleontological. Many years ago I discovered in an old box tucked away in the attic of Scovel Hall at Wooster a set of “Magic Lantern Slides” used in geology courses. I came across them again recently and thought I would share these ancient scenes. Lantern slides were the 19th Century equivalent of PowerPoint, so generations of Wooster geology students must have sat in rapture looking at these colorful images. (At least that’s how I imagine them now viewing my PowerPoint slides!) The above imagined seashore view includes the crocodylian Teleosaurus atop the layered rocks, Ichthyosaurus immediately below, four long-necked Plesiosaurus on the left, an orange cluster of the crinoid Pentacrinus rooted inexplicably in the beach sand, and a scattering of ammonite and oyster shells.  The caption on the image says these animals lived during “the Secondary Epoch of the Earth’s history”. We would now say this is a Jurassic scene. The ichthyosaur looks the most odd to us. Not only is it crawling on the land, it lacks a dorsal fin and the characteristic bi-lobed, shark-like tail. These were later discoveries about ichthyosaurs made only after specimens were found with skin impressions.

These are chromolithograph slides, each stamped “T.H. McAllister, Optician, N.Y.”. McAllister was the most prominent of many American producers of lantern slides in the late 19th century.

In 1855, Waterhouse Hawkins finished sculpting life-sized models of these extinct animals, along with many others, for the Crystal Palace gardens in London. He was advised for the anatomical details by Sir Richard Owen (1804-1892), a hero of paleontology but not a fan of Darwinian evolution. He is responsible for the dinosaurs of Waterhouse Hawkins looking rather mammalian. Most of these extraordinary animal statues still exist.

    To be fair, Owen didn’t really have a whole lot to go on, with the early reconstructions, and we all are part of that same tetrapod lineage, aren’t we, as mammals? It’s not such a great leap to go from giant crocodilian reptiles we knew, combined with mammalian morphology, to produce the first guesses at dinosaurian form. From a time-contextual point of view, Owen did the best he could with the terribly incomplete fossils he had at his disposal (Buckland’s earliest finds were just a jawbone of Megalosaurus, and Mantell’s earliest Iguanodon samples weren’t much better, although they would be improved upon rapidly, as shown by the “Iguanodon” fossil slab in the London Natural History Museum). Owen may have been arrogant, but he’s certainly not the first scientist (or human) to suffer from that conceit, is he? I do think he must have been Dickens’ inspiration for designing a Scrooge character, given the extant photos of him….
    Those are great early “transparencies,” by the way–thank you for sharing them! In your next post, don’t forget to show the “exhibition” dinner from the Crystal Palace, inside Hawkins’ Iguanodon (and make certain to point out its “horn” and the foibles of vertebrate paleontology!). We all have a lot to learn about science through the misadventures of (mostly) 19th century dinosaur-mania.
