Marcelo Krause is an Argentinian paleontologist, and is a CONICET researcher working at the Paleontological Museum Egidio Feruglio (MEF) in Trelew, Chubut. He specialises in the study of fossilized soil (paleosol), and studying trace fossils (ichnology).
In 2015, Marcelo was on an expedition to search for fossilized insect nests. He ended up discovering one along a cliff face, and the resulting bee's nest Cellicalichnus krausei was named after him.
Marcelo has helped describe a number of dinosaurs, and was one of the paleontologists from the MEF who described the largest dinosaur discovered, Patagotitan mayorum.
