Exporting Moroccan fossils without a licence has been illegal since 2020, but the law has been a little unclear for those outside Morocco. In our new paper, my colleague and friend Kawtar Ech-charay clearly explains the law, using our field area as a case study: link.springer.com/article/10.1...

Out in @nature.com today, we shake up the ornithischian family tree. Remember those weird Late Cretaceous iguanodontians, the rhabdodontids? Well they're weird because they aren't iguanodontians. They're ceratopsians. Well, at least some of them are... www.nature.com/articles/s41...

After we published the new specimen of #Spicomellus a few weeks ago, we were contacted by George Blasing, who said he'd bought some on the commercial market, and wanted to return it to Morocco. It arrived last week. Thanks George for doing the right thing in the name of science!

Last but not least from the NHM field trip to Morocco - we visited a lake which had dried up after its water dwindled away. It's a sight that could become more common around the world as a result of climate change, but there are ways to turn things around 👇 www.nhm.ac.uk/discover/mor...

This is how much Spicomellus changed in the last four years: 2021 reconstruction by Joschua Knüppe on left based on single rib known then; 2025 reconstruction by Matt Dempsey based on new material on right. My guess: when we get articulated material it's going to prove to be even weirder.

It's a journey that wouldn't have been possible without help of many people in Morocco, not least Professor Driss Ouarhache. His knowledge of the region's geology helped to track down the bones to the mudstone slopes of the Middle Atlas, revealing a dinosaur hotspot in the process. (2/4)

It also highlights the incredible significance of Moroccan palaeontology. A very sad part of this story is that Spicomellus fossils - very likely parts of exactly the same skeleton that we describe - are for sale having been illegally poached & smuggled. I hope these find their way back to Morocco.

Have you ever heard of #Spicomellus? It’s one of the world’s strangest dinosaurs. Its rib bone has spikes fused to it - something unheard of in any other animal! But now, more of the skeleton has been uncovered - and it's even stranger than anyone imagined... (1/4) 🧵
