A new Li/Mg paleothermometer from pteropod shells - Scientific Reports
1+ mon, 1+ week ago (850+ words) Pteropod Mg/Ca values (Table 1, Fig. S1b) vary on average from 0.20 to 0.84 mmol/mol, while spot measurements range from 0.13 to 3.93 mmol/mol (Table S1), with an average RSD of 37%. The comparatively high intra-shell variability observed for both Li/Ca and Mg/Ca…...

Confirmation that bryozoan animals were present during the Cambrian explosion
1+ mon, 1+ week ago (65+ words) Bryozoans are marine invertebrates that live in colonies and have long been considered absent from the Cambrian explosion — a rapid evolutionary event that began around 538 million years ago. Newly discovered fossils from the Cambrian period reveal that the bryozoan phylum…...
A unicellular relative links aggregative multicellularity to animal origins
1+ mon, 1+ week ago (227+ words) How animals evolved complex multicellularity from their unicellular ancestors remains unanswered. Unicellular relatives of animals exhibit simple multicellularity through clonal division, formation of multinucleate coenocytes, or aggregation. 1 Therefore, animal multicellularity may have evolved from one (or a combination) of these…...
