“…In our specimen, borings along the right‐lateral edge of the costals on the right side of the carapace where the marginals are disarticulated are interpreted as clionaid sponge encrustation marks, possibly Entobia based on the interlaced morphology of the bored chambers. Other types of sponges (mainly Hexactinellida) are found in this section as isolated clumps and as sponge‐microbialite buildups (Reolid 2010), so it is possible that the carapace acted as a suitable firm ground for them, amidst the surrounding loosely consolidated sediment. The rest of the carapace is covered by a network of interlaced Gnatichnus borings produced by the grazing activity of regular echinoids while the carapace was resting in the sediment with the colonization of clionaid sponges and disarticulated section exposed at the surface (Plate 1E, F, G).…”

Abstract:The Jurassic was an important period in the evolution of Testudinata and encompasses the origin of many clades, and this is especially true of Jurassic turtles from Western Europe. A new genus and species of Late Jurassic turtle, Hispaniachelys prebetica gen. et sp. nov. from the upper Oxfordian of the Prebetic (Southern Spain), is described on the basis of postcranial material. The specimen is the only known tetrapod from the Mesozoic of the Prebetic and the oldest turtle from southern Europe. A mosaic of characters indicates this is a new genus: it displays basal features including dorsal epiplastral processes ⁄ reduced cleithra, no medial contact of the extragulars and a long first thoracic rib, alongside derived characters including an absence of mesoplastra and the vertebral 3 ⁄ 4 sulcus crossing neural 5. The phylogenetic position of the new taxon is hard to resolve, and it might be either a paracryptodire or a basal testudine, but it is distinct from Plesiochelys. A complex taphonomic history is shown by a range of overlying grazing traces and bioerosion on the carapace. The carapace was subsequently overturned and buried ventrally up, terminating grazing activity, and was then bored by sponges before final burial. Scanning electron microscopy reveals phosphatic microspheroids associated with bacterial decay in the vascular cavities of the cancellous bone, suggesting the carapace may have acted as a closed microenvironment in which decay-derived authigenic minerals formed.

“…A biomineralization model based on the interaction of acidic organic macromolecules with inorganic compounds has been proposed studying the microbialites of reef cavities and modern atolls (Reitner 1993;Reitner et al 1996;Camoin et al 1999;Sprachta et al 2001;Gautret et al 2004;Heindel et al 2010Heindel et al , 2012. The role of decaying organic matter in biomineralization processes has been debated and a carbonate precipitation influenced by non-living organic substrates has been proposed (Leinfelder & Keupp 1995;Pickard 1996;Pratt 2000;Neuweiler et al 2003;Reolid 2007Reolid , 2010Guido et al 2019b). Acidic amino acids, particularly humic and fulvic acids that may derive from degraded metazoan organic matter during early diagenesis may promote carbonate mineral nucleation, because Ca 2+ -binding carboxyl groups, which are structurally similar to CO 2− anions in carbonates, may correspond to the lattice spacing of carbonate minerals.…”
