For the ARCHEA blog post on Megalodon, I wanted to choose a human to give that mighty shark a true sense of scale. And in choosing a human, I thought I'd choose a truly awesome one to introduce to all of you. Everyone, meet Cam Muskelly. 
Cam Muskelly is an award-winning Avocational Palaeontologist & Geologist in Georgia, in the southeastern United States. Cam is a Science Writer, Fossil Hunter, Tweeter & YouTuber with ASD. He gives talks on a number of subjects related to palaeontology & geology — all of which are a delight! 
In tomorrow's ARCHEA blog post, you can get a sense of the scale of Cam vs Megalodon in the Scuba vs Shark image. Cam is a respectable five feet, five inches tall or 1.65 metres tall. Otodus megalodon is more than ten times larger. Now, Cam is a brave man and reached his hand out in the image as an act of solidarity to this beautiful shark from ancient seas, but fortunately for him (and you and I) there is 20-million-years separating his hand and those chompers. Megalodon had more than 276 teeth in their cage-like mouths and produced a nasty bite!

Join him for a fun, short chat about two important Permian fossils from his personal collection, which he uses for education and outreach across his home state. He shared this talk as part of the Discovery Day: National Fossil Day for the KU Natural History Museum.
