Dr Katie StrangHere’s some wee 330 million year old crinoid ossicles that wonderfully illustrate their five-fold radial symmetry. Nature is awesome 🖤 #ScottishFossils #ScottishGeology
Edde@palaeokatie time can be mind boggling. 330 million years… if they lived a meter ago, the oldest humans are a mere millimeter back in time. 🤯 And ALL of our history, known and unknown or reconstructed from scraped bones and pieces of clay pots, fits in that millimeter. 🤯²
@edde yeah it’s cool! And crinoids still exist today so their record extends for 500 million years 😀
