What is admtools?

The age-depth engine under a small stratigraphy stack, growing one adapter at a time

admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.

What is StratPal?

Building the pipeline that carries simulated evolution into stratigraphic position

StratPal provides pipelines for stratigraphic paleobiology: simulate trait evolution or event data at specimen level, apply niche and taphonomic effects, then push the result through an age-depth model into stratigraphic position. The pre_paleoTS S3 class introduced in 0.2.0 is the interchange format the design rests on, with reduce_to_paleoTS() connecting it to the paleoTS package for downstream fitting. The two most recent releases extend the pipeline outward: FossilSim integration in 0.4.0, and in 0.6.0 the last_occ and range_offset wrappers that express biostratigraphic precision as a function of taphonomy, ecology, abundance and stratigraphy.

The age-depth engine under a small stratigraphy stack, growing one adapter at a time

◆ Current state

admtools estimates and manipulates age-depth models, with the generics time_to_strat() and strat_to_time() as the transformation layer a small stratigraphy stack is built on. Since 0.1.0 it has accumulated the S3 vocabulary that work needs — sac for sediment accumulation curves, timelist and stratlist for time- and height-associated data — and then adapters outward: pre_paleoTS for StratPal and paleoTS in 0.4.0, FossilSim taxonomy and fossils objects in 0.5.0, and age-to-time transformation for FossilSim in 0.6.0. Version 0.5.0 also added what it calls basic functionality for depth-depth models alongside the age-depth ones.

◆ Where it's heading

This package moves in step with StratPal, from the same group: admtools 0.4.0 shipped its pre_paleoTS transformations fifty-seven minutes before StratPal released the class itself, and both took on FossilSim within a month of each other in spring 2025. The pattern is consistent — establish generics, define classes, then connect to whatever package the field already uses. The depth-depth work is the one thread pointing inward rather than outward, and it is still described as basic.

◆ Prediction

Depth-depth models are the obvious thing to finish, since they mirror age-depth machinery the package already has; expect any release here to be shadowed by a matching change in StratPal within weeks either side.

◆ Current state

◆ Where it's heading

This package develops in lockstep with admtools, its sibling from the same group — admtools 0.4.0 added pre_paleoTS transformations fifty-seven minutes before StratPal 0.2.0 shipped the class itself, and both picked up FossilSim integration in spring 2025. The direction is consistently outward: rather than adding simulation models, StratPal adds adapters so its output can feed established paleontology packages and be fed by them. Releases are small and frequent, and each names a specific connection or wrapper.

◆ Prediction

Expect the next release to add another adapter or convenience wrapper rather than a new simulation model, following the paleoTS and FossilSim pattern, with the matching change in admtools landing within weeks either side.
