Polish term or phrase: kalcytowe krążki (łodyga)
Kolejnym elementem wyróżniającym się w planie budowy liliowca jest jego giętka łodyga. Składa się ona z kalcytowych krążków lub pięcioboków przez które dokładnie w środku przechodzi wewnętrzny kanał osiowy (łączy on górę i dół zwierzęcia).

Problem ze znalezieniem tłumaczenia: kalcytowe krążki i pięcioboki

calcite rings (of the stem)
Explanation:
Liliowce (Crinoidea), to grupa kopalnej fauny, która pojawiła się na scenie życia już w ordowiku, a co ciekawe przetrwała do dziś! Ich nazwa pochodzi od greckich słów krinon – lilia i eidos – kształt. Te przypominające bardziej kwiaty niż zwierzęta organizmy zaliczane są do szkarłupni – wyłącznie morskich, wysoko zorganizowanych bezkręgowców. Ciało liliowca składa się z łodygi (columna), którą zwierzę przytwierdzało się do podłoża za pomocą korzenia (basis); kielicha (calyx) oraz ramion (brachia) okalających otwór gębowy. - http://www.geocaching.com/geocache/GC5Y5MC_liliowiec-przy-ma...

może lepiej "stalk" zamiast "stem"?

---------

The majority of living crinoids are free-swimming and have only a vestigial stalk. In those deep-sea species that still retain a stalk, it may reach up to 1 metre (3.3 ft) in length, although it is usually much smaller. The stalk grows out of the aboral surface, which forms the upper side of the animal in starfish and sea urchins, so that crinoids are effectively upside-down by comparison with most other echinoderms. The base of the stalk consists of a disc-like sucker, which, in some species, has root-like structures that further increase its grip on the underlying surface. - https://en.wikipedia.org/wiki/Crinoid

Part of why the crinoids were so well preserved has to do with the structure of their skeletons, the researchers said. Like sand dollars, crinoids have skin on top of a hard calcite shell. In the case of crinoids, their long bodies are made up of thousands of stacked calcite rings, and each ring is a single large calcite crystal that contains pores filled with living tissue. When a crinoid dies, the tissue will start to decay, but calcite will precipitate into the pores, and calcite is stable over geologic time. Thus, organic matter may become sealed whole within the rock. - http://researchnews.osu.edu/archive/oldbiomarkers.htm
