Toothy Grin is the ‘side gig’ of Brisbane-based palaeontologist Dr Jonathan Cramb. Palaeontology barely covers rent, so I’m hoping that you'll buy many t-shirts.

Toothy Grin evolved from my yearly tradition of designing a Christmas card for family and friends. People started telling me that I should sell them (the cards, not the family and friends), so I did. I also design little button badges for museum shops.

You can buy Toothy Grin cards and badges from the Queensland Museum shop, Brisbane, Qld (Cards available online); the Eromanga Natural History Museum, Eromanga, Qld and the Australian Age of Dinosaurs Museum, Winton, Qld.
