2014) makes it possible to study carbon isotope values of organic matter in conodont elements
without their demineralization.
known to be related to the Triassic age would be as follows: Prioniodella Prioniodellides, Hindeodella multihamata, Hindeodella nevadensis, Lonchodina nevadensis, Hindeodella triassica, Ligonodina triassica, Diplodella lautissima, Pachycladina oblique, Hadrodontina anceps, Ellisonia triassica, hibardella subsymmertica, Parachirognathus geiseri, Prioniodella decrescens, Enantiognathus bitortus, Chirognathus sp., Xaniognathus sp., and Anchiognathudos sp.
"We created high resolution 3D models of the conodont elements
using x-rays from a particle accelerator in Japan, using it like a giant CT scanner.
distribution in the samples from the Kohtla section.
1997) yielded only two poorly preserved conodont elements
of middle Arenig to Llanvirn age (Nowlan 1981).
Despite the great abundance of conodont elements
, few age-diagnostic species were obtained from carbonates of the Wink Member.
In the Pakri Cape section 58-97% of conodont elements
were redeposited, while conodonts were derived from several underlying strata (Lofgren et al.
The morphology of the conodont elements
was studied with SEM (VEGA3 TESCAN of the Institute of Geology Komi SC UrB RAS, Syktyvkar, Russia), X-ray micro CT (SkyScan 1272 of St.
For correlation and investigation of morphologic changes of conodont elements
, data from some additional outcrops and borehole sections were used.
Lithological samples, residues and conodont elements
are housed in the 'Inventario Paleontologia Universita di Modena e Reggio Emilia-IPUM' at the Dipartimento di Scienze Chimiche e Geologiche, Universita degli Studi di Modena e Reggio Emilia, Modena, Italy.
In total, 26 samples from the Homerian and Gorstian yielded more than 400, mostly fragmented conodont elements
. Only few samples were barren.
Interestingly, sample OM6-3 also contained a few conodont elements
that resemble E.
