The Sponge Character in the Fossil Record. Sponges are one of the first animal groups to diverge from the metazoan lineage; however, their time of origin is not resolved, partly because of the lack of undisputed fossils at the time that molecular clocks estimate their origin (Wörheide et al. Reference Wörheide, Dohrmann, Erpenbeck, Larroux ...Mar 1, 2018 · Early sponges had mineralised skeletons and thus should have a good preservation potential: the lack of sponge fossils in Precambrian strata may be due to genuine absence of sponges.

Fossil eggs worldwide are very rare. In almost all cases an egg-shaped fossil is something else. Most fossil "eggs" are weathered and rounded rocks, rather than fossils. siderite nodules and concretion s can have smooth, oval shapes and may appear like eggs. Other rocks may be rounded in streams into oval shapes.
