Catalog entries: Mutabella;
Type images:Distinguishing features: Like Tenuitella but larger and usually with umbilical tooth plate and/or supplementary apertures
NB These concise distinguishing features statements are used in the tables of daughter-taxa to act as quick summaries of the differences between e.g. species of one genus.Most likely ancestor: Globigerinita - at confidence level 3 (out of 5). Data source: Pearson et al. 2001, p.131.
Geological Range:
Last occurrence (top): at base of Serravallian Stage (2% up, 13.8Ma, in Serravallian stage). Data source: Total of range of species in this database
First occurrence (base): in lower part of Burdigalian Stage (26% up, 19.3Ma, in Burdigalian stage). Data source: Total of range of species in this database
