 Similarly, private sketches of mammoth fossils drafted by Yakutsk merchant Roman Boltunov in 1805 were likely never intended for scientific publication, but their function—to communicate the life appearance of an animal whose tusks he had found in Siberia and was hoping to sell—nevertheless establishes it one of the first examples of paleoart by today's definition.Boltunov's sketches of the animal, which depicted it without a trunk and boar-like, raised enough scientific interest in the specimen that the drawings were later sent to St. Petersburg and eventually led to excavation and study of the rest of the specimen.Cuvier went on to produce skeletal restorations of extinct mammals of his own.
