Taxonomy

Catalog entries: Dendrospyris turriturcica turriturcica

Original description: Shell, when viewed anteriorly or posteriorly, showing an elliptical to subangular cephalis without median constriction, and a nar-rower, open, distally tapering thorax. In side view, the shell is markedly compressed.
QTThe sagittal ring extends somewhat more than half the distance from the collar pores to the apex, and from its top arises an apical spine which is incorporated into the shell wall and then extends as a short thorn from the apical surface. Surface of lattice shell puckered at the level of the top of the sagittal ring. Primary and secondary lateral bars well developed.QTLattice shell robust, with pores of unequal size, subeircular on the cephalis and tending to be longitudinally elongated on the thorax. Vertical pore distinct. Termination of thorax uneven, with irregular lamellar teeth not markedly differentiated from the bars separating adjacent pores.

Biostratigraphic distribution

Geological Range:
Last occurrence (top): within Paleogene Period (23.03-66.04Ma, top in Chattian stage). Data source: Lazarus et al. 2015 - "P age group"
First occurrence (base): within Paleogene Period (23.03-66.04Ma, base in Danian stage). Data source: Lazarus et al. 2015 - "P age group"

Plot of occurrence data:

• Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
• Triangles indicate an event for which a precise placement has been suggested
• (NB There is no histogram as there are no occurrence records for the taxon in the Neptune database) Parent: Dendrospyris
