StratPal vs tealeaves: at a glance
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.
What is tealeaves?
A leaf-temperature model that finished its job in 2020 and has stayed finished
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.

Building the pipeline that carries simulated evolution into stratigraphic position
◆ Current state
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.
◆ 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.

The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.
◆ Where it's heading
This is finished scientific software. The arc runs from a 1.0.0 that already described the full model, through a usability decision in 1.0.1 to accept unitless values and assign units rather than demand them, to a 2020 cluster of compatibility and correctness work around publication. Nothing since has touched the model, and the 2022 release is pure paperwork. Its most instructive entry remains 1.0.5, where a new feature silently produced incorrect parameter crossing and the fix arrived with tests to pin the behaviour.
◆ Prediction
Expect nothing unless a dependency or CRAN check forces a release; on this record any such release will be documentation and packaging rather than a change to the energy balance.
