“…Other trilobite genera also have a broad Gondwanan distribution during the Devonian, e.g . the calmoniid Eldredgeia , with occurrences in the Bolivia, Brazil (Amazon and Parnaíba basins), and South Africa, and the homalonotid Burmeisteria , with records in the Brazil (Amazon, Parnaíba, and Paraná basins), Falkland Islands, South Africa, and Ghana 1 , 15 , 19 , 26 .

Metacryphaeus is a calmoniid trilobite genus from the Devonian Malvinokaffric Realm, exclusive to the Gondwanan regions. It includes eleven species, which are for the first time included here in a single phylogenetic analysis. The resulting hypotheses establish relations among the Metacryphaeus species with few ambiguities, also suggesting the inclusion of both Plesiomalvinella pujravii and P. boulei within the genus, as originally considered. The results of palaeobiogeographic analyses employing the Dispersal-Extinction-Cladogenesis (DEC) model reinforce the hypothesis that Bolivia and Peru form the ancestral home of Metacryphaeus. The radiation of the genus to other Gondwanan areas took place during transgressive eustatic episodes during the Lochkovian–Pragian. The Lochkovian dispersal occurred from Bolivia and Peru to Brazil (Paraná and Parnaíba basins) and the Falklands, and Pragian dispersal occurred towards South Africa. Dispersal events from Bolivia and Peru to the Parnaíba Basin (Brazil) were identified during the Lochkovian–Pragian, suggesting the presence of marine connections between those areas earlier than previously thought.

Moulting Patterns in Trilobites from the Devonian of Paraná Basin

In general, trilobites had their moulting performed by the breakdown of the librigena, a region (more external) situated on the cephalon of those animals. However, phacopid (calmonid and homalonotid) trilobites from the Paraná Basin have shown a Salterian moulting pattern, differing from the other trilobites. This moult pattern consisted of the separation of all the cephalon to the thorax. So, this paper intends to demonstrate information regarding preservation standards resulting from behavior(moult) of trilobites from the Paraná Basin, as found in the literature specialized and studied scientific collections.

“…This crinoid fauna has no similarity with the fauna of South Africa (except by Ophiocrinus stangeri ), but has taxa associated with the eastern United States of America, and mainly Europe and northern Gondwana (Scheffler et al, 2013; Scheffler, 2015). Although elements that have similarity to Europe and northern Gondwana Old World Realm have long been known in other Devonian invertebrate groups of South America (e.g., Katzer, 1897, 1903, 1933; Clarke, 1913; Isaacson and Perry, 1977; Melo, 1985, 1988; Fonseca and Melo, 1987; Isaacson and Sablock, 1990; Fonseca, 2004; Carvalho and Ponciano, 2015; Távora et al, 2017), the Malvinokaffric fauna has always been considered to have great similarity throughout its distribution area, including southern Brazil, Bolivia, and South Africa (Boucot, 1971, 1988; Boucot and Racheboeuf, 1993). Therefore, these data suggest that: (1) the known crinoids are still a very small part of the actual class diversity in this period for South America; and/or (2) this class, unlike almost all other faunal groups of the Malvinokaffric Realm (e.g., trilobites, brachiopods, conulariids, bivalves, gastropods), has a high degree of endemism within each sedimentary basin, even among the typically Malvinokaffric basins.…”

Two new families and three new genera and species of Crinoidea from the Icla and Belén formations, Bolivian Devonian, are described. The material is identified as Meperocrinus angelina n. gen. n. sp., from the Icla Formation of the Sub-Andina region, Tuberocrinus lapazensis n. gen. n. sp. and Aenigmaticumcrinus rochacamposi n. gen. n. sp., both from the Belén Formation of the Bolivian Altiplano. Meperocrinus angelina n. gen. n. sp. is an Emperocrinidae, a family described from the Silurian of the United States of America. Tuberocrinus lapazensis n. gen. n. sp. is assigned to a new family of Dimerocrinitacea, the Tuberocrinidae n. fam., which is closely related to Pterinocrinidae that already has representatives in Bolivia (Apurocrinus sucrei McIntosh), Argentina (Pterinocrinus? australis Haude), and Colombia (Bogotacrinus scheibei McIntosh). Aenigmaticumcrinus rochacamposi n. gen. n. sp. is also as assigned to a new family of Dimerocrinitacea, the Aenigmaticumcrinidae n. fam.; a family with very distinctive features. These data demonstrate that the Malvinokaffric crinoid fauna in Bolivia has a mixed origin, with forms that arrived in South America from Europe (Old World Realm) and United States of America (Eastern America Realm) during the late Silurian or earliest Devonian, as well as a local stock, which evolved to highly endemic lineages.
