..., as well as the genera Acarinina and Igorina. Our new isotopic and biogeographic data suggest that the acarininids evolved from a photosymbiotic ancestor (which we identify as Praemurica inconstans or early representatives of Praemurica uncinata ), but also demonstrate that photosymbiosis did not trigger...

...D. Clay Kelly; Anthony J. Arnold; William C. Parker Abstract Praemurica uncinata displays pronounced allometry during its evolutionary transformation into Morozovella angulata, an important species in Paleocene planktic foraminiferal biostratigraphy. The allometry is such that smaller specimens...

... of diversification and δ 13 C change ( Fig. 2A–C ). The lower stratigraphic occurrence of Praemurica uncinata and its descendents, the morozovellids, at this site compared to Site 528 suggests that either Morozovella began to diversify before final δ 13 C recovery in the tropics or a section of younger sediment...
