T outcrop. Fossils incorporate in situ and reworked dinocysts and acritarchs, acritarchs, brackish and freshwater algae, exotic projectate pollen, lowland tree and herb brackish and freshwater algae, exotic projectate pollen, lowland tree and herb pollen, pollen, bisaccate pollen, fern and moss spores, and fungal hyphae. The analyses had been all bisaccate pollen, fern and moss spores, and fungal hyphae. The analyses had been all carried carried out in the genus level. Before performing the statistical analyses, taxonGeosciences 2021, 11,6 ofout in the genus level. Prior to performing the statistical analyses, taxon abundances were log transformed to emphasize the relative contributions of all taxa, effectively growing the weight of uncommon components . Then, sample counts were percent transformed to alleviate any potential effect of sample size differences. Ultimately, Euclidean distances  were computed involving every single pair of samples and captured in a distance matrix to assess differences in their biotic composition.Table 1.

These strategies excel at summarizing substantial quantitative datasets, extracting dominant patterns, and plotting trends in clear intuitive displays. HCA and DCA happen to be utilised successfully for decades in lots of disciplines, but in particular so in paleobiology and ecology exactly where they reveal similarities and differences in the composition of biotas via space and time, and help in interpreting environmental controls on species distributions . HCA is actually a classification tool that iteratively partitions samples into groups based on differences in their fossil assemblages. Initially, the HCA algorithm hyperlinks the two samples with all the shortest distances into a group. Subsequent, a new distance matrix is computed from the remaining samples. The sample with all the shortest distance for the 1st group is linked to it. This procedure repeats till all samples are combined into groups plus the groups are fused into clusters [50,61]. In this way, each and every cluster represents a set of samples with equivalent palynological compositions. Probably the most related samples will have the lowest Euclidean distances. DCA  is a popular ordination technique for detecting gradients of ecological transform and relating this variability to underlying environmental components . The relative position of samples inside DCA space reflects their biotic similarity. Samples that plot close to 1 a different have additional similar biotic compositions than samples that plot far from one another. DCA captures the key biotic variation along DCA axis 1. Subsequent axes explain smaller sized amounts of variation. This quantitative method to biofacies definition permits the fossil data to reveal important relationships that tell their own story unconstrained by implications from other information. The resulting biofacies are direct products from the statistical analyses, base.
