KnowraCrown groupLinked fromLinked fromThe 17 pages that link to Crown group, each with the reason it gives.All 17Related 11Narrower topic 2Compared with 4CarnivoraRelated: Living Carnivora form a crown group whose ancestry anchors the order’s definition.Evolution of mammalsRelated: This definition separates crown Mammalia from many extinct mammal-like synapsids.Fossil calibrationRelated: A fossil's placement inside or outside a crown group changes which divergence it constrains.Stem groupCompared with: Stem-group taxa fall outside this group, whose living members set its boundary.CaniformiaRelated: The crown-group definition clarifies which living lineages belong in a clade.CetartiodactylaRelated: This distinction helps separate living cetartiodactyl lineages from extinct stem relatives.MorganucodonRelated: This definition clarifies why mammaliaforms such as Morganucodon need not be mammals in the strict sense.ArchosauriformesRelated: Archosauria is the crown group nested within the broader Archosauriformes.MetatheriaRelated: The distinction between Metatheria and Marsupialia depends on whether extinct stem relatives are included.Early vertebrateCompared with: The distinction separates early stem forms from the lineage containing living vertebrates.Evolution of tetrapodsRelated: Crown-group definitions distinguish living tetrapod ancestry from earlier stem tetrapods.PlacentaliaRelated: Its definition determines which fossils count as placentals rather than stem eutherians.NeornithesNarrower topic: This definition distinguishes Neornithes from extinct bird lineages outside its crown.ReptiliomorphaRelated: The distinction separates crown amniotes from the broader set of reptiliomorph stem relatives.SeymouriaCompared with: Seymouria falls outside the amniote crown group despite sharing some of its traits.AsteriornisNarrower topic: Asteriornis is notable as a candidate close to the crown group of modern birds.CanadaspisCompared with: Whether Canadaspis falls inside or outside a crown group affects its evolutionary significance.
