Description Summary of collected samples. N is the number of specimens collected, S the number of species found, a and b the number of singletons and doubletons (respectively) amongst those species, ACE is Chao and Lee (1992)'s Abundance-based Coverage Estimator and u is Good (1953)'s coverage estimator. Depth are given in mbsf (meters below sea-floor) and age estimates are taken from the Neptune Database embedded age model (Lazarus et al. 1995), which is scaled on Berggren et al. 1995.

Description Whole-fauna dataset diversity vs untrimmed Neptune dataset subsampled diversity. A and B: Respectively, in-sample species richness and range-through diversity in our whole-fauna dataset. C: Diversity computed from the untrimmed Neptune dataset with five different type of subsampling: UW (black line), OW (dashed black line), CR (light grey line), O2W (dashed light grey line) and SQS (bold dark grey line). Magnetostratigraphy from Berggren et al. (1995).

Description Effect of range-trimming on diversity. Black line is without any trimming, dark grey line with a light trimming (3% at the top, 1% at the bottom), grey line with a moderate trimming (5 and 3%) and light grey line with a very strong trimming (12 and 8%).

Description Comparison betweeen diversity trends using 0.5My bins and 1My bins (bold: with 1My bins, thin: with 0.5My bins). A. Range-through diversity in whole-fauna data. B. Range-through diversity in subsampled Neptune dataset (black: UW; grey: SQS). The quotas for 1My-bins subsampling are 20 collections for UW and 0.70 for SQS.

Description Completeness metrics. A. Several species accumulation curves from samples of various ages. B. Species-accumulation curve on a typical sample (sample 120-751A-6H-6, 98/102cm, Late Miocene). Bold black curve is the species accumulation curve; light grey curve and dashed light grey line are, respectively, the de Caprariis et al. (1976, 1981) curve-fitting and its asymptote.
