Early Sponge Evolution: a Review and Phylogenetic Framework
Available online at www.sciencedirect.com ScienceDirect Palaeoworld 27 (2018) 1–29 Review Early sponge evolution: A review and phylogenetic framework a,b,∗ a Joseph P. Botting , Lucy A. Muir a Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, 39 East Beijing Road, Nanjing 210008, China b Department of Natural Sciences, Amgueddfa Cymru — National Museum Wales, Cathays Park, Cardiff CF10 3LP, UK Received 27 January 2017; received in revised form 12 May 2017; accepted 5 July 2017 Available online 13 July 2017 Abstract Sponges are one of the critical groups in understanding the early evolution of animals. Traditional views of these relationships are currently being challenged by molecular data, but the debate has so far made little use of recent palaeontological advances that provide an independent perspective on deep sponge evolution. This review summarises the available information, particularly where the fossil record reveals extinct character combinations that directly impinge on our understanding of high-level relationships and evolutionary origins. An evolutionary outline is proposed that includes the major early fossil groups, combining the fossil record with molecular phylogenetics. The key points are as follows. (1) Crown-group sponge classes are difficult to recognise in the fossil record, with the exception of demosponges, the origins of which are now becoming clear. (2) Hexactine spicules were present in the stem lineages of Hexactinellida, Demospongiae, Silicea and probably also Calcarea and Porifera; this spicule type is not diagnostic of hexactinellids in the fossil record. (3) Reticulosans form the stem lineage of Silicea, and probably also Porifera. (4) At least some early-branching groups possessed biminerallic spicules of silica (with axial filament) combined with an outer layer of calcite secreted within an organic sheath. -
First Report of Crumillospongia (Demospongea) from the Cambrian of Europe (Murero Biota, Spain)
First report of Crumillospongia (Demospongea) from the Cambrian of Europe (Murero biota, Spain) DIEGO C. GARCÍA-BELLIDO, MARÍA EUGENIA DIES ÁLVAREZ, JOSÉ ANTONIO GÁMEZ VINTANED, ELADIO LIÑÁN & RODOLFO GOZALO The demosponge genus Crumillospongia, originally described from the Burgess Shale (middle Cambrian of Canada), has only been cited from lower and middle Cambrian localities of North America and China. The taxon is now also de- scribed from uppermost lower Cambrian rocks of the Murero Lagerstätte (Zaragoza Province, NE Spain). Crumillospongia mureroensis sp. nov. is a small to medium sized sack-shaped to elongate demosponge characterized by the presence of densely packed pores of three sizes, considerably larger than those in any other species of the genus. The Spanish material represents a link in the chronostratigraphical gap between the Chinese and North American material. • Key words: Crumillospongia, demosponges, early Cambrian, Lagerstätte, taphonomy, Murero, Spain.

Lower and Middle Paleozoic Stratigraphic Successions
CHAPTER 2 LOWER AND MIDDLE PALEOZOIC STRATIGRAPHIC SUCCESSIONS Middle Arenigian quartzite beds (upper Armorican Quartzite) in the Estena river section, Cabañeros National Park Gutiérrez-Marco, J.C. Rábano, I. Liñán, E. Gozalo, R. Fernández Martínez, E. Arbizu, M. Méndez-Bedia, I. Pieren Pidal, A. Sarmiento, G.N. It has already been explained how the formation of the Iberian Massif, where the Iberian Peninsula base- ment crops out, is closely linked to the development of the Late Paleozoic Variscan orogeny. The result was the intense shortening and deformation of the marine sediments previously deposited along the vast Gondwana continental margins during the Early and Middle Paleozoic. The Iberian Massif contains the most extense and fossiliferous exposures in the European Variscan orogenic chain. Its different struc- tural and paleogeographic zones include important stratigraphic successions from the Cambrian to the Devonian periods (García-Cortés et al., 2000, 2001; Gutiérrez-Marco, 2006), making up one of the key geological frameworks to understand the latest Precambrian and Paleozoic evolution of the Iberian Peninsula and Western Europe, and with an abundant record of geological and biological global events.

It is now generally known that the youngest stages of trilobites found as fossils are minute ovate or discoid bodies, not more than one millimetre in length, in which the head por tion greatly predominates. Altogether they present very little likeness to the adult form, to which, however, they are trace able through a longer or shorter series of modifications. Since Barrande2 first demonstrated the metamorphoses of trilobites, in 1849, similar observations have been made upon a number of different genera by Ford,22 Walcott,34':*>':t6 Mat thew,28- 27' 28 Salter,32 Callaway,11' and the writer.4.5-7 The general facts in the ontogeny have thus become well estab lished and the main features of the larval form are fairly well understood. Before the recognition of the progressive transformation undergone by trilobites in their development, it was the cus tom to apply a name to each variation in the number of tho racic segments and in other features of the test. -

Ptychopariid Trilobites in the Middle Cambrian of Central Bohemia (Taxonomy, Biostratigraphy, Synecology)
Ptychopariid trilobites in the Middle Cambrian of Central Bohemia (taxonomy, biostratigraphy, synecology) VRATISLAV KORDULE A revision of ptychopariid trilobites from the Middle Cambrian of central Bohemia is presented. With a few exceptions, they were previously referred only to Ptychoparia striata. Three genera are recently distinguished: Ptychoparia Hawle & Corda, 1847, Ptychoparioides Růžička, 1940, and Mikaparia gen. nov. Seven species are described: three are revised, four are new, and two is left in open nomenclature; their stratigraphical ranges and significance are discussed. A new stratigraphical subdivision of the Middle Cambrian of the Skryje-Týřovice area is suggested, including three assemblage zones and three barren zones. Four substrate and bathymetrically controlled trilobite associations are recognized in the Skryje-Týřovice area. • Key words: Bohemia, Middle Cambrian, trilobites, new taxa, biostratigraphy.

As in the previous paper, only published species are considered because illustrations are not possible. Most of the text is arranged in alphabetical order according to genera, exceptions being made in a few cases where several members of a family are kept together. ALBERTELLA Walcott, 1908 Four species were described by Walcott as belonging to Alhertella, viz, the genotype A. helena, and A. bosworthi, A. levis, and A. pa- cifica. The last named, which comes from Asia, is in reality an inde- terminate fragment and must await the finding of further material before its proper generic assignment can be made. Several new spe- cies of Albertella are in hand beside those recognized below in the disr cussion of the three previously described American species. -
