Iberomesornis and Feather

S1 E5: Andy travels back to the time of iberomesornis - a bird that lived in the forests of Spain 127 million years ago. His mission is to find some blue feathers belonging to the bird to replace the one he and Hatty accidentally lost back at the museum. Along the way he takes to the skies with one of the largest flying pterosaurs that ever lived. But will he succeed before the museum opens?
