Palaeoxyris is now thought to be the shark egg morphotype of the family Hybodontoidae.
Quote from Fischer & Kogan (2008):
"Based on the size differentiation and frequency of two Palaeoxyris species and different hybodont shark remains
from the Stephanian lacustrine Wettin strata of the Saale Basin, Germany, SCHNEIDER (1986) was able to assign
both egg capsules to their putative producers (P. helicteroides to Lissodus lacustris and P. carbonaria to
Limnoselache [Sphenacanthus SOLER-GIJÓN, 1997] vicinalis; this attribution was confirmed by GEBHARDT,
1988) (Fig. 5), which occurred in the same strata but in different sedimentary facies. The capsules were mainly
found in fluviatile-palustrine deposits, whereas skeletal remains were restricted to pelagic lacustrine sediments.
So it seemed plausible that both hybodont shark species used the shore area of the lake for spawning."
