Creative taxonomy — it's what happens when scientists discover an as-yet unnamed species and find some way to connect it to a person, place, or thing. Sometimes that person/place/thing is famous. Sometimes it isn't. Sometimes the connections between the two make perfect sense. Other times the connections are more tenuous. So when we heard the news that a prehistoric lizard had recently been named after President Barack Obama (scientific name: Obamadon gracilis), we were obviously keen to find out the reasoning for it.
