Transitional Fossil Inside Tiktaalik rosaea T-Shirt

Are you in transition, whether literally or metaphorically? Let your wry evolutionary biology side shine with this design featuring the Tiktaalik rosaea, a 375 million year old fossil fish which contained bones and anatomical adaptations showing the evolutionary transition from fish living in water to tetrapods living on land. Specifically, its fins have thin ray bones for paddling like most fish, but this organism also has sturdy interior bones that would have allowed Tiktaalik to prop itself up in shallow water and use its limbs for support on land. Comes with the saying "Transitional Fossil Inside" that will make others do a double-take on how you feel evolution-wise. Evolutionary biology / biopsychology attitude tee for anyone in transition!
