In this short discussion, palaeontologist Dave Hone and Iszi Lawrence chat with podcaster Suzy Buttress about the strangeness of bird eyes... from iris colour and pupil shape, to owls, crocodiles and the frustrating problem of soft tissue in fossils.

Could dinosaurs really have had the slit pupils made famous by Jurassic Park? Or have we been picturing dinosaur eyes all wrong? Expect: birds, dinosaurs, crocodiles, giant marine reptile eyeballs, weird owl anatomy, and some surprisingly unsettling turkey dissection stories.

This is an extract from Series 5 Episode 4 with Suzy Buttress from the Casual Birder podcast.
