Vertebrate remains from the Muen Mountain on Edge\u00f8ya are shown to have exceptional X-ray contrast due to a combination of sulphide and sulphate permineralisation and pseudomorphing. Radiography imaging of a previously described specimen, PMO 219.250, revealed new and spectacular details such as more carpals, teeth, and skull sutures. Teeth and skull characters are taxonomically significant. supporting the referral of PMO 219.250 to <jats:italic>Phalarodon<\/jats:italic> and further suggesting an affinity to <jats:italic>P<\/jats:italic>. <jats:italic>atavus<\/jats:italic>. Three sulphur phases were identified, with the sulphide sphalerite (ZnS) being the highest temperature phase, followed by the sulphate baryte (BaSO<jats:sub>4<\/jats:sub>), and the sulphide pyrite (FeS<jats:sub>2<\/jats:sub>). Sulphate permineralisation is also seen in specimens from the Upper Jurassic on Svalbard. We suggest that sulphur-rich fluids have flowed and dissolved barium from the shales and deposited the sphalerite and baryte, and that this could be linked to the Cretaceous HALIP. The Jurassic specimens are only permineralised by baryte, while the Triassic specimens have also been permineralised, but mainly pseudomorphed by baryte with crystals of sphalerite. Lithology differences appear to have controlled the compaction of the Triassic specimens, while the Jurassic specimens have retained their three-dimensional shape due to the baryte emplacement relatively earlier in their depositional history. Although soft tissues are not preserved, the excellent X-ray contrast in the Middle Triassic specimens is reminiscent of pyritised fossil sites such as the Hunsr\u00fcck Slate (Devonian), Beecher\u2019s Trilobite Bed (Ordovician), and the La Voulte-sur-Rh\u00f4ne marls (Jurassic).<\/jats:p>","DOI":"10.1371\/journal.pone.0285939","type":"journal-article","created":{"date-parts":[[2023,5,31]],"date-time":"2023-05-31T17:44:15Z","timestamp":1685555055000},"page":"e0285939","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Exceptional X-Ray contrast: Radiography imaging of a Middle Triassic mixosaurid from Svalbard"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8920-2204","authenticated-orcid":true,"given":"Victoria S.","family":"Engelschi\u00f8n","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aubrey J.","family":"Roberts","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruben","family":"With","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d8yvind","family":"Hammer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,5,31]]},"reference":[{"key":"pone.0285939.ref001","first-page":"34","article-title":"Begriff und Bedeutung der Fossil-Lagerst\u00e4tten","author":"A.
