Progress and problems in the assessment of flower morphology in higher-level systematics [PDF]

open access: yes, 2018
Floral features used for characterization of higher-level angiosperm taxa (families, orders, and above) are assessed following a comparison of earlier (precladistic/premolecular) and current classifications.

Constraining uncertainty in the timescale of angiosperm evolution and the veracity of a Cretaceous Terrestrial Revolution. [PDF]

open access: yes, 2018

The Fossil Record of Angiosperm Families in Relation to Baraminology [PDF]

open access: yes, 2020
To help estimate the number and boundaries of created kinds (i.e., baramins) of flowering plants, the fossil record has been analyzed. To designate the status of baramin, a criterion is applied that tests whether some but not all of a group’s ...
