Scat scans: How lasers are teasing secrets and techniques from historical poo

Coprolites, or fossilised faeces, have at all times been slippery clients. However now we will use X-rays to see inside them, they’re yielding contemporary insights into historical ecosystems

THE highly effective X-rays on the European Synchrotron Radiation Facility in Grenoble, France, have been used to look inside some intellectual stuff: papyri from historical Egypt, Neolithic cave artwork, Roman scrolls buried within the eruption of Vesuvius and artefacts from Henry VIII’s warship Mary Rose. Then, each once in a while, Per Ahlberg rocks up with a load of previous crap.

Ahlberg, a palaeontologist on the College of Uppsala in Sweden, actually is aware of his shit. Or, as palaeontologists name it, coprolites. These lumps of fossilised faeces have been identified to science for practically 200 years, however have been lengthy thought to be the arse finish of palaeontology. “They’re not essentially the most glamorous of fossils they usually have been typically neglected,” says Ahlberg. However due to Grenoble’s X-rays, they’re now having fun with a golden age.

Coprolites (from the Greek for “dung stones”) first got here to prominence within the 1820s, when beginner palaeontologist Mary Anning and College of Oxford geologist William Buckland realised the nodules they stored discovering in Lyme Regis, UK, have been fossilised faeces. The invention sparked a short bout of “copromania” amongst beginner fossil hunters. Nevertheless, skilled scientists turned their noses up.

Within the Nineteen Nineties, Karen Chin on the College of Colorado, Boulder, revived scientific curiosity in coprolites with a paper describing a “king-sized” specimen from Canada that she stated was in all probability expelled by a Tyrannosaurus rex. It was 44 centimetres lengthy, 16 centimetres extensive, 13 centimetres excessive and crammed stuffed with pulverised bone that will nicely have come from a younger dinosaur, presumably a triceratops.

Partially digested

Since then, coprolites have yielded all types of wonderful finds, together with undigested …
