Paleopathology of a fossil fish from the Solnhofen Lagerstätte (Upper Jurassic, southern Germany)

Fossil Crustaceans as Parasites and Hosts

“…However, other causative agents are possible so the involvement of copepods cannot be confirmed. Lesions in fishes can have diverse causes, making it difficult to identify in fossil fishes without preserved pathogen remains (Petit, 2010;Petit and Khalloufi, 2012).…”

Constraining the Deep Origin of Parasitic Flatworms and Host-Interactions with Fossil Evidence

“…However, the characteristics of these (Luk sevics et al, 2009) and other pathologies like skin lesions (Petit, 2010;Petit and Khalloufi, 2012) are insufficient to attribute them to particular group of parasites confidently, or even rule out potential other causes. Interestingly, they also overlap temporally with the presence of blister pearls in Devonian ammonoids (Rakoci nski, 2012), which might also have been caused by parasitic flatworms, although no conclusive evidence for a parasitic flatworm infestation was found (De Baets et al, 2011.…”

Grouping behaviour impacts on the parasitic pressure and squamation of sharks

“…The comparatively good representation of vertebrate squamations in the fossil record ensures a wide applicability of this approach to extinct taxa. Data extracted from this novel methodological framework might be crucial to complement the records of host-parasite body fossils in association [83][84][85][86][87][88][89] and pathologies [90,91]. Still, this more anecdotal evidence has the unique potential to provide estimations of parasitic intensity or prevalence as well as information on the nature of ectoparasites and their attachment site preferences [92][93][94][95][96][97].…”
