“…Ever since CaCO 3 biomineralization became widespread, during the Cambrian ( 8 , 9 ) and Ordovician ( 10 ) radiations of marine animals and algae, it has played a major role in the carbon cycle ( 11 ), affecting and being affected by the ambient environment on geologic time scales ( 12 , 13 ). Because of their persistence in the fossil record, biominerals in general, and CaCO 3 biominerals in particular, provide a major archive of the evolutionary history of life and environments on Earth.…”

“…latitude worldwide distribution into a single high latitude Ordovician refuge as a consequence of the increased ecological pressure during the initial series of Early Ordovician radiations preceding the Great Ordovician Biodiversification Event [43,44]. Palaeoscolecids appear to have been much less affected by comparison based on their much broader palaeobiogeographic distribution during the Ordovician including Gondwana [21,22,41], Laurentia [42], South China [36][37][38] and Avalonia [23,39,40], which suggests a degree of ecological selectivity in the survival of Early Palaeozoic scalidophorans.…”

“…The fact that no other selkirkiids have been discovered from these multitude of Ordovician sites with soft tissue preservation worldwide, despite their durable tube construction, suggests that the polar distribution of S. tsering might be legitimate rather than a preservation artefact. We hypothesize that selkirkiids might have shrunk their Cambrian low latitude worldwide distribution into a single high latitude Ordovician refuge as a consequence of the increased ecological pressure during the initial series of Early Ordovician radiations preceding the Great Ordovician Biodiversification Event [43,44]. Palaeoscolecids appear to have been much less affected by comparison based on their much broader palaeobiogeographic distribution during the Ordovician including Gondwana [21,22,41], Laurentia [42], South China [3638] and Avalonia [23,39,40], which suggests a degree of ecological selectivity in the survival of Early Palaeozoic scalidophorans.…”

“…The skeletal marine phyla appear for the first time (Sperling et al 2013, Wood et al 2019, and ecological interactions become a driver of evolution (Hsieh et al 2022). Following the initial late Ediacaran diversifications and subsequent Cambrian Explosion of animal life from ~538 to 522 million years ago (Maloof et al 2010, Nelson et al 2022, biodiversity levels stagnated for the next ~40 million years until the Great Ordovician Biodiversification Event (GOBE), where familial diversity increased dramatically (Servais et al 2023, Stigall et al 2020). The early initial radiation of organisms in the Ediacaran (Tarhan 2018, Wood et al 2019) is firmly established in the Cambrian, with new organisms shaping the seafloors and pelagic realms in terms of both the ecosystems in these environments and their physical and chemical state.…”

“…Even so, with the disappearance of the first animal reefs at the end of the early Cambrian, there is an interval of arguably low diversity (Harper et al 2019) and low abundance of skeletonizing animals (Pruss et al 2010). The drivers of this later Cambrian-Early Ordovician plateau of diversity are poorly understood, and the marine biosphere was likely influenced by multiple causal factors and feedbacks (both physical and biological) operating across a range of spatiotemporal scales that ultimately gave way to the Middle Ordovician biodiversification event (e.g., Stigall et al 2020).…”
