I'm not sure if there has been found _heritable_ phenotypic changes, but I certainly wouldn't rule it out. We know of other environmentally-induced heritable changes. Why rule out predation-based ones?

"We know of other environmentally-induced heritable changes. Why rule out predation-based ones? The only way any externally influenced phenotypic change can be passed on is if the phenotype change is due to a genotypic change in the gametes. I know of no way knowledge of a predator would cause a gene change in a germ cell. If you have any links to this phenomena I would be interested.

On top of the morphological similarities, the stratum the fossil is found in determines the age of the fossils, which has to be sequential in direct lineages but can be 'out' to some degree in sister species. Ecologies are also considered when deriving sequences.
how much area is considered acceptable when using this method?
