🐞 There is amber in Belgium; it is 50 myo and only yielded a handful of animal inclusions: a termite, a true bug, a mite.

Crinoid tube feet recovered from the Ordovican of Canada ! Their organisation reveals these crinoids fed in a wider ranger of postures than most modern stalked crinoids, in a way convenient for feeding in low-energy environments. #echinoderms #softtissues royalsocietypublishing.org/rsos/article...

Exceptional soft-tissue preservation reveals the oldest evidence for tube feet and their ecological significance in crinoids

Abstract. Tube feet are extensions of the echinoderm water vascular system that play essential roles in feeding and ecology in living crinoids. However, on

A juvenile iguanodontian preserves both spikes and scales in its skin that are different from integumentary structures in either non-avian dinosaurs or extant squamates and may have had a defensive function, according to a paper in Nature Ecology & Evolution. go.nature.com/3MeZb7O #Paleosky 🧪
