Catalog entries: Aspis murus
Original description: Shell of three (?) segments; cephalis quite irregularly shaped, very thick-walled, with rather large pores with polygonal pore-frames, fairly rough-surfaced and covered with many irregular short tubes (?) externally; internal cephalic skeletal elements invisible; it is uncertain whether the skeletal elements were broken or not present. Thorax cylindrical, slightly widening distally, thick-walled, penetrated by many circular pores with polygonal pore-frames regularly longitudinally arranged, becoming larger distally. Marked constriction at the lumbar stricture; abdomen (?) broken, not constricted, widely opened distally, rather thin-walled.

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
- Histogram - Neptune occurrence data from DSDP and ODP proceedings. Pale shading <50 samples in time bin. Interpret with caution & read these notes
