Compute a diversity / origination / extinction curve for a clade across geologic time, binned by period, epoch, or age — answers "plot dinosaur genus diversity across the Mesozoic." Pass a clade-inclusive base_name (or base_id, the same clade by resolved taxon id — exactly one of the two) and bound the span by a named interval (e.g. "Mesozoic") or a max_ma/min_ma range; choose what to count (genera, species, or families) and the bin resolution. The full bin set returns inline — a diversity series is a bounded set of geologic intervals — so you read the curve, the turnover, and the per-bin origination/extinction directly. Counts reflect SAMPLED diversity, biased by collection effort and rock availability, not true past diversity.
