PeterNakridletia_ord1.n._-_pterosaur_parasites.pdf Less than 1 Mb. I like to post items which throw a new light onto the fossil record, and/or generally clarify /obscure (for whatever reason) matters. A really terrific paper!!Recommended! Mesozoic and Paleozoic parasitism, and mutualism, and commensalism, and trophic amensalism, ETC. Paleopathology, we know way too little about ecological interactions in the past.
dittmars12862-015-0568-x.pdf object of contention(from the GAO article,which is freely accessible online and/or might be in several libraries here on this very forum : Dinosaurs/feathers or hair ,external appearance of extinct vertebrates, possible host-/parasite co-evolution,would the past biogeography of host and parasites coincide,,,,etc
Thought it would be nice to post an oldie(1922)** yakowecolinteractgastropcrinoidZoolAnzc1922_0291-0294.pdf The author "leans towards" Simroth's theory that commensalism (and/ or mutualism)evolved from "parabiosis*",because the gastropod can sometimes be found attached to the crinoid stele . *apparently:the simple phenomenon of attachment,without connotations about causes or substrate preference . The frequent (obligatory,almost?)co-occurence of the fossils is explained by the life-long interaction itself: when the crinoid dies,the gastropod dies. (probable naticid gastropod boreholes can be found on some "infested" crinoids) The attachment scar of the gastropod are concentric,the gastropod aperture has an excentric location,to keep the aperture covering the anal aperture of the crinoid. The erosion/(resorption?) of the anal proboscis may be due to the gastopod Small circular depressions are tentativel attributed to early ontogenetic failed predation attempts by juvenile gastropod **and I am aware of the more recent literature on this subject havent read yet
