Sentence examples for maximum age constraint from inspiring English sources

The upper (maximum) age constraint of 120 Ma for the calibrations above corresponds to the oldest known monocot fossils [ 52].

Additionally, calibrations based on vicariance events, in contrast to fossils, also provide a maximum age constraint [ 78].

Additional, a maximum age constraint for the phyllostomids (3) was set with an exponential distribution to 34 MYA with an arbitrarily lower limit of 11.5 MYA.

Although previous studies have recognized a long gap in the fossil record of the angiosperm stem lineage [ 13, 21, 37], there is no indisputable argument in favor of one particular maximum age constraint for the crown node of angiosperms.

This maximum age constraint is justified by the fact that tricolpate pollen is a synapomorphy of eudicots and that the absence of such pollen in well sampled earlier sediments worldwide is well documented.

It is remarkable, however, that Lundberg et al. arbitrarily selected 144 my (informed by the fossil record of actinopterygians) as the maximum age constraint for the split of gymnotiforms and siluriforms.

Applying different maximum age constraints to the crown node of angiosperms highlighted the sensitivity of inferred ages estimated for the deepest nodes of Magnoliidae.

In addition, we test the sensitivity of magnoliid divergence times to the choice of relaxed clock model and various maximum age constraints for the angiosperms.

Maximum age constraints were also placed at the most recent common ancestor of core Eudicots (124 mya; [ 71, 73, 74]), and Eudicots and Monocots (130 mya; [ 71]).

As in previous work [ 5] we used the recommendations of Benton and Donoghue [ 35] for the minimum and maximum age constraints of the mouse-rat divergence.

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.
