They incorrectly used fossil ages as species divergence times for crown groups, while in fact the former should merely form minimum-age bounds for the latter.
Vogue's minimum age limit for models is 16.
Is there a minimum age limit for AIs taking part?
Based on Wahlberg et al. [ 61], the stem age of the subtribe Mycalesina was constrained to be 40 ± 5.5 Million Years Ago (Mya) with a normal distribution prior between the minimum and maximum age bounds.
Here, the 'hard' minimum bounds were based on the minimum age of the oldest fossil that can be confidently assigned to a particular node.
We used the same prior distribution for the age of both Aleiodini and Clinocentrus MRCAs, an exponential distribution with a minimum age of 34.7 MYA and a 45.1 MYA upper bound (95% limit).
This is not surprising, considering that the internal priors have soft lower bounds but are strong enough to behave as if they have a hard bound, thereby constraining other internal nodes more than the minimum age constraints in the PL analysis, where the only lower bound is the fixed root.
The minimum age is 16, and there is no maximum age limit.
Fossil evidence was used to calibrate the minimum age of Centrophoridae, Etmopteridae and Dalatiidae to be 65 Ma (C/T boundary) with a soft upper bound of 100 Ma (beginning of the Upper Cretaceous).
Because most of the fossil record we used in this study only provided a minimum age for the origin, when setting the priors we used the fossil ages as the lower bounds.
These uniform distributions were bounded either by the age of the fossil (Table 2) and 1E100 Myr for minimum age constraints, or by the appropriate maximum age (see above) and 0 Myr for maximum age constraints.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
