“…Circular to subcircular traces, produced on the surface of an early Maastrichtian holasteroid echinoid test (northern Germany), and consisting of a more or less pronounced rim surrounding a central depression, were interpreted by Neumann and Wisshak (2006) as the attachment scars produced by probable parasitic foraminifera during a syn-vivo infestation; since the characteristic rim of these traces would be the result of the host-skeletal overgrowth around the attached parasite as defense mechanism. Wisshak and Neumann (2006) described 27 U-shaped borings (Caulostrepsis isp.)…”

Abstract.-Among invertebrates and both in modern and ancient marine environments, certain echinoderms have been and are some of the most active and widespread bioturbators and bioeroders. Bioturbation and/or bioerosion of regular and irregular echinoids, starfish, brittle stars, sea cucumbers and crinoids are known from modern settings, and some of the resulting traces have their counterparts in the fossil record. By contrast, surficial trails or trackways produced by other modern echinoderms, e.g., sand dollars, exhibit a lower preservation rate and have not yet been identified in the fossil record. In addition, the unique features of the echinoderm skeleton (e.g., composition, rapid growth, multi-element architecture, etc.) may promote the production of related traces produced by the reutilization of echinoderm ossicles (e.g., burrow lining), predation (e.g., borings), or parasitism (e.g., swellings or cysts). Finally, the skeletal robustness of some echinoids may promote their post mortum use as benthic islands for the settlement of hard-substrate dwellers.

“…The Jurassic is thus an important interval for studying predation on echinoids because of their rapid evolutionary innovations (Kier , ; Simms ), as well as growing evidence for biotic interactions (Vermeij ; Borszcz & Zatoń ). Echinoderms are attractive model organisms to study biotic interactions because their long fossil record has much data on predation and parasitism (Neumann ; Donovan & Jagt ; Baumiller & Gahn , ; Radwańska & Radwański ; Neumann & Wisshak , ; Deline ; Villier ; Wisshak & Neumann ; Radwańska & Poirot ; Borszcz & Zatoń ) extending into the Recent (Schultz ; Baumiller et al . , ).…”

Using microscopy and spectroscopy tools, we succeeded in identifying undescribed diminutive epibionts (as epibiotic bacterial colonies) both on exceptionally well‐preserved fossil shrimps and on extant taxa (N. Robin, S. Bernard, J. Miot, M.‐M. Blanc‐Valleron, S. Charbonnier & G. Petit, submitted). This study outlines the ecological parameters of this totally newly recognized interspecific association. To this aim, the systematics and environmental setting of fossil and modern decapod hosts are described; count of bacterial colonies is made to assess prevalence and intensity; scanning electron microscopy is used to illustrate colonial growth patterns; and histological sections of the extant colonies nested in cuticle are stained to determine their incidence on the carapace of their decapod hosts. Thus, the prevalent and intense association is found on decapods of the superfamily Penaeoidea Rafinesque‐Schmaltz 1815 occupying up to 2 cm2 of the entire carapace. The association is here observed in deep environments such as that of the Jurassic La Voulte‐sur‐Rhône Lagerstätte. A non‐random distribution of colonial growth patterns is determined; it illustrates a favourite access site along the ventral margin of the shrimp carapace. SEM images and stained sections reveal strong colony embedment within the cuticle, but also damage such as erasing of the cuticular layers. This bioeroding effect, possibly linked to a feeding benefit to the bacteria, brings this interspecific association that has existed, for at least 160 myr, near to parasitism. In addition to illustrating a rare case of interaction in Recent forms that could be described due to previous recognition in fossils, it constitutes a textbook example of the preservation of intimate interactions through geological time.
