Nobumichi Tamura also known simply as NobuTamura is a paleoartist who was born in France. He has created more than 1,500 Creative drawings of dinosaurs (Commons-licensed) and other prehistoric animals. Many of his art are hosted on Wikimedia Commons. His reconstruction of a juvenile Rubeosaurus attracted huge audience. This was a ceratopsian dinosaur from the Cretaceous period. Working at the Berkeley National Laboratory, Tamura recounts in the piece, when he first started to explore the topic in Wikipedia about 10 years ago, he set to work when he was struck by the absence of illustrations. He says that it wasn’t always an easy sailing. This was partly because paleontology has seen many advances over the past few decades that have deeply changed views of what these prehistoric animals looked like in life. His first drawings were not really successful, because he just drew the dinosaurs like he saw them when he was a kid.
They weren't quite accurate and were imprecise enough that his early drawings were rejected by Wikipedia editors and they were removed from their site. Rather than finding a new hobby or giving up all together, he just worked smarter and harder, soliciting feedback from the editors of Wikipedia on how he could better render these extinct species. He also read the latest scientific articles describing the extinct animals he was working on and started sketching. As time went by his art got better and better. To date, Tamura has illustrated close to 2000 dinosaurs and other prehistoric animals and a good number of his illustrations continue to be in use.
