A new paper published in Nature reveals new information about Aegirocassis benmoulae, showing that around 480 million years ago they were the largest creatures on the planet at the time, measuring approximately seven-feet long. Fossil specimens of the animals from the Early Ordovician Fezouata Biota of Morocco also provide insight into anomalocaridid trunk flaps.
A video by the Yale Peabody Museum of Art features one of the authors of the paper, Peter Van Roy, explaining the new fossil specimens and the information scientists were able to glean from them.
