Despite being the basal member of the cynodont clade, they already showed some of the advanced mammalian characteristics, but Procynosuchids bore resemblance to the Therocephalians.
Based on a study that included a single undescribed Malagasy species in the spider genus Anelosimus, investigators found that this species could be grouped within a clade of NewWorld social species.
The audience was entertained by singers Rod Stewart and Susan Boyle and watched pictures of the Queen's Baton arriving in Glasgow landing by a seaplane on the clade.
Within this group, analyses usually place bats with a clade that contains pangolins, carnivores, and ungulates, or as the sister group of shrews, moles, and maybe hedgehogs.
And they found that Toxodon and Macrauchenia — Darwin's original two weirdos — looked like they belonged in the same clade, meaning they'd come from a common ancestor.
Starting in the late 19th century, most paleontologists thought that turtles belonged in the clade we now call parareptilia, because they shared the same basic skull structure with other parareptiles.
Sea scorpions and true scorpions are actually sister clades that both belong to a Subphylum known as Chelicerata, an ancient group of arthropods that first appeared in the oceans of the Cambrian Period.
