The use of temporal information from the fossil record as data in phylogenetic inference has been criticised however, with concerns ranging from the incompleteness of the geological record to the non-clocklike evolution of morphology . Inferring the phylogenetic position of fossils can only be achieved using morphological …The fossil record shows that this is likely to be the case, first in the retention of spore-like packets attached in short linear chains (e.g., Fig. 3B), but more substantially in sheets of paired spore-like cells, as seen here in Grododowon orthogonalis Strother 2017 (Fig. 4, A and B, and fig.
