Shonisaurus Gets a Makeover (giant Nevada ichthyosaur had teeth after all)
"Shonisaurus has large, pointed teeth that are deeply rooted"
See from SVP 2016:
"These fossils confirm the presence of teeth in all ontogenetic stages."
***
As far as I can find, this new evidence for a toothed Shonisaurus popularis still has not been formally published. Is there any news on a formal paper?

History of the Shonisaurus discovery site
*****
What Riley Black's interesting article does not mention is the status of the huge Shonisaurus sikanniensis from British Columbia, which IS apparently toothless.
Note that the huge Shonisaurus sikanniensis was reclassifiedÂas Shastasaurus in 2011 (free pdf):
However, the Royal Tyrrell Museum website still calls the fossil Shonisaurus
sikanniensis
Mark Witton's 2020 blog about giant ichthyosaurs classifies the British Columbia giant as Shonisaurus sikanniensis but does not mention the new evidence that Shonisaurus popularis had strong teeth in its jaws...

The title of this final episode is a bit misleading. The first 10 minutes are about recovering microfossils from the Lower Cretaceous clay pit site in Balve, with bones and teeth of dinosaurs, crocodiles, pterosaurs, and mammals, plus a rib fragment from an Iguanodon-like dinosaur in the lab. Only about the last 6 minutes are about Jurassic ichthyosaur fossils found in Westphalia (JÃllenbeck) in much harder rock.
