Tillyardembiids from the Lower Permian of Chekarda, general views (a,c,h), close-ups of body areas covered with pollen, taken under a fluorescence microscope (b,d–g,i,k,l) and pollen grains obtained from the specimens (j,m,n). (a,b,d,e) PIN 1700/3727; (c,f) PIN 1700/1164; (g–i,k,l) PIN 1700/4286; (j) Cladaitina pollen (from PIN 1700/1164); (m) Cordaitina pollen (from PIN 1700/4286); (n) Striatites pollen (from PIN 1700/4286). Scale bars = 2 mm (a,c), 1 mm (h), 400 µm (e,d), 250 µm (b,i,l,g,f), 300 µm (k), 20 µm (j,m,n). Roman numbers indicate abdominal segments; pt, prothorax; ms, mesothorax; mt, metathorax.
