What do trilobites, woodlice and hedgehogs have in common?! They can all curl up into a ball when threatened (or trilobites did, before going extinct 252 million years ago). These curled Calymene trilobites, known as ‘dudley bugs’, are around 425 million years old. #FossilFriday
1st year SET class getting to know some local biodiversity, with garden orb spiders, pill bugs, woodlice, centipedes and a lot of slugs! Some had to face their fears with the spider! 🕷️ St Joseph's Rush ann marie lynch #irishbiodiveristy #arachnids
