Looking for ID help. I originally thought the fossils were triticites because I found some chert with definite triticites at the same location. But the fossils in the pictured rock are indeed elliptical shaped from the top view (like triticites), but are circular from the side view. The rock is limestone from Pocahontas County, Iowa. The third through sixth photos are microscopic (~40x). The last photo shows a coral located on the underside of the same rock. Fusinilid? corpoloite? ichnofossil? Or what? Your ID info will be appreciated.
