What's the difference between coccolith and discolith?

Coccolith


Definition:

  • (n.) One of a kind of minute, calcareous bodies, probably vegetable, often abundant in deep-sea mud.

Example Sentences:

  • (1) Three acidic polysaccharides (PS-1, PS-2, and PS-3) were extracted from the coccoliths with EDTA and were separated and purified by differential precipitation with magnesium ions and chromatography on DEAE-cellulose.
  • (2) Bibliographic data concerning the variability of coccosphere and coccoliths during the life-cycle of two extant Coccolithophorid species (Calcidiscus gr.
  • (3) The coccoliths from the species Emilania huxleyi (Lohmann) Kamptner contain a water-soluble acid polysaccharide.
  • (4) The method is illustrated by application to mixtures of the constituent sugars of the capsular polysaccharide from Klebsiella type 57, alpha 1-acid glycoprotein, mucus glycoproteins, and the methylated, acidic polysaccharide from the coccoliths of Emiliania huxleyi (Lohmann) Kamptner.
  • (5) A large-scale cultivation of the Coccolithophoridae was worked out and a new procedure for isolating coccoliths was developed.
  • (6) This species is useful for the study of mineralization, because it produces calcified scales known as coccoliths in homogeneous cell culture.
  • (7) A polysaccharide associated with coccoliths of the marine alga Emiliania huxleyi (coccoliths are elaborately shaped calcite biominerals) was isolated and its influence on the crystallization of calcium oxalate monohydrate crystals was studied.
  • (8) sibogae) are summarized and completed by new observations on the structure of the proximal shield by fossil coccoliths.
  • (9) C-occolithophoridae, a group of mostly unicellular algae, possess a cell wall containing calcified plates, called coccoliths.
  • (10) These observations also point out the possibility of a diachronous evolution of the two shields of the same coccolith type, underlining the necessity for a better knowledge of the proximal shield structure, usually somewhat neglected.
  • (11) Such intermediate coccoliths have been previously described from the Badenian (middle Miocene) of central Europe.
  • (12) The possible role of the polysaccharide as a heterogeneous matrix in coccolith formation is discussed.
  • (13) leptoporus in the latest Miocene (Messinian) assemblages from three oceanic localities (central Pacific, eastern equatorial Atlantic and southwestern Indian oceans) indicates the co-occurrence of two types of coccoliths: (1) typical C. gr.
  • (14) A polysaccharide with similar properties could be isolated from subfossil coccoliths of E. hyxleyi (about 1000 years old).

Discolith


Definition:

  • (n.) One of a species of coccoliths, having an oval discoidal body, with a thick strongly refracting rim, and a thinner central portion. One of them measures about / of an inch in its longest diameter.
