Background info. This paper has been in review for 450 days as the editors struggled hard to acquire a second review due to the "complexity" of the paper (and was then accepted with minor revisions). The complexity being that the paper reveals the striking gap between the purported theory and actual application of the Coexistence Approach based on the so-far only CA/Palaeoflora study (Quan et al., Palaegeogr. Palaeoclim. Palaeoecol. [P^3], 2012) providing full documentation of the used data. Our in-depth comparison reveals that the famed precision of CA/Palaeoflora studies is based on poor climate data riddled by inconsistencies such as smaller family intervals than those of their constituent genera, erroneous or dubious fossil-NLR associations, inconsistent, partly illogical taxon filtering, and frequent violations of some or all four basic assumputions by those NLRs that actually define coexistence intervals. Probably to obscure these severe deficiencies, CA/Palaeoflora studies generally refrained from adequate documentation of the used data, albeit Utescher et al., P^3, 2014, recommend themselves to document all used climate data and NLR associations (however, not done in any CA/Palaeoflora paper co-authored by Utescher and colleagues in 2015 or 2016)
