Inspired by the genius of MC Escher, these mathematically magical modern dinosaurs fit together with puzzling perfection. Set comes with 7 tuatara tessellations engraved on wood. Girls and boys of any age (recommended age 3 and up) delight in finding different ways of assembling this clever little puzzle. 
As a side note, it can also be used as a trivet for hot pots. Who knew? ;)
