I love the Cephalopods and the Crinoid specimens where the calyx connects to the stalk.

[@KOIstories]

Thanks for the comment!

The " internal cast" at 11:08 is actually the internal mold of a goniatite. The specimen at 12:11 is likely geologic rather than a fossil. That is a coral at 12:28 called "Michelinia sp."

Cool! Thanks for the help with identification! The rock at 12:11 could also be some kind of secretion like plant resin or may be a result of pathological outgrowth.

Great video. Well done. The group of unknown fossils contained a gastropod at the top, probably Pseudozygopleura. The two that look like arrows re part of a crinoid arm where it splits into two arms. The darker one below is still unknown, at least to me.

the small nautiloid is actually a Goniatite...ancestor of ammonites.
