The world has seen locusts for many, many years. Long before the 8th plague of Egypt, these large juicy insects have been swarming, feasting and surviving for years. Million of years. Hundreds of millions of years. Delicately preserved fossils of these familiar little insects are known from a few sites around the world. Solnhofen, in Germany is one such site.
Solnhofen is more famously known for the discovery of the infamous Archaeopteryx, the feathered reptile that is almost a bird (fun blog post here checking out what the researchers think about Archaeopteryx). As well as the 11 specimens of this beautiful dino-bird, and a feather, the Solnhofen limestones have preserved a huge number of ancient creatures, including, starfish, fish, shrimps, horseshoe crabs, dragonflies, reptiles, pterosaurs, and locusts. (You can see a number of beautiful fossils with incredible detail here.)
150 million years ago, Solnhofen was a little bit different. It was a beautiful lagoon, surrounded by islands. The extremely high salt (or salinity) of the waters meant that life could not live there. There was also no oxygen deeper down, meaning the muds also lacked any life, including worms and bacteria that would normally eat away flesh. Because of the lack of life in this lagoon, any animals (or plants) that fell beneath the waves were slowly covered in fine sediment, and preserved in exquisite detail. The fine feathers of Archaeopteryx and the delicate wings of a locust would be preserved for eternity.
Here is what you have been waiting for, this weeks bad cast. Here she is. I was going to say, ‘She is beautiful’. But I can’t. Because she is not. Not at all. She lacks a dash of colour to brighten her up. She lacks any detail. It could easily be something you may buy for your three year old niece to paint and draw on. But it is a real cast of a fossil. Accessioned with the fossils. Embarrassingly, here it is, our cast of a 150 million year old locust:
Such a really, really bad cast. You can kind of see why they did it back in 1906; To show how insects have been around for millions of years, and are (ahem) beautifully preserved. Fossils from Solnhofen should look like this. Unfortunately our cast doesn’t look like one of those.
I am not sure if this, or any other bad cast, has ever been on display. I quite like to think they have, back when the display cases were made of lovely wood, and the dangerously thin glass was so easy to lean on. To have purchased and actually invested in this and other casts, they surely must have been displayed.
I often wonder what people would have thought when they saw such bad casts like this. Would they have squinted to try to ‘see’ what the label says it is? Or would they have even noticed that they were bad? It may be like high definition TV today; we notice if it isn’t HD because we have it. But back when we didn’t have HD, we didn’t complain.
