The area is marked by a major fault system defining the Beinn na Leac Fault Block, and field survey shows this to comprise a rollover anticline in the SW, with extensional movement towards the NE along an oblique transfer fault, the Main Beinn na Leac Fault. The fault system was reactivated after the Last Glacial Maximum. Survey of a distinctive ridge of detached scree along the Main Beinn na Leac fault shows it to have involved a single movement of at least 7.12 m vertical displacement, arguably the greatest fault movement since before the Younger Dryas in Scotland. The present work confirms that the scree became detached during the Younger Dryas, but finds that it overlies a lacustrine deposit of at least 5.6 m of laminated sediments from a lake which had begun to accumulate earlier. Radiocarbon dating of peat overlying the lake sediments gave 10 176–10 315 cal years BP, but morphological and stratigraphical evidence indicates that drainage of the lake occurred earlier and only shortly before movement of the scree. Possible causes of displacement at the fault system are briefly discussed.","PeriodicalId":49556,"journal":{"name":"Scottish Journal of Geology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43879397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was a crucial intervention and, for the hospitality and generous assistance that Moreno arranged for the expedition's leader, William Speirs Bruce (Fig. 1), the presentation of a few rock specimens might seem scant reward, although as an additional mark of respect Bruce named Point Moreno on the expedition's published map of Laurie Island (Brown et al. 1906, p. 145): the name is still valid – 60° 44′ S, 44° 41′ W. Bruce would have been deeply satisfied by the knowledge that his donation of specimens from the South Orkney Islands had initiated the development of an Antarctic collection at the Museo de La Plata.

In recent years, new vertebrate fossils have emerged from the Early–Middle Jurassic of the Isle of Skye, Scotland; however, much more is known about Skye's dinosaur fauna than its crocodylomorphs. Here we report new crocodylomorph material collected from Jurassic marine deposits at Prince Charlie's Cave on the NE coast of Skye. The specimen is a small cobble containing postcranial elements from an individual that is considerably larger in size than previous crocodylomorphs described from Skye. Based on features of the vertebrae and osteoderms, the specimen is assigned to Thalattosuchia, an extinct clade of semi-aquatic/pelagic crocodylomorphs. Specifically, the sub-circular and bean-shaped pit ornamentation on the dorsal surface of the osteoderms in alternating rows suggests affinities with the semi-aquatic lineage Teleosauroidea. Although the ornamentation pattern on the osteoderms is most similar to Macrospondylus (‘Steneosaurus’) bollensis, we conservatively assign the specimen to Teleosauroidea indeterminate. Regardless of its precise affinities and fragmentary nature, the specimen is the first thalattosuchian discovered in Scotland and is the most northerly reported Jurassic thalattosuchian globally, adding to our understanding of the palaeobiogeography and evolution of this group.

Mention was made in passing of Jameson’s role as an early proponent of Scottish glaciation, but the secondary literature sources cited have their primary origin in the notes of another of Jameson’s students, James David Forbes (1809–68), which are now held in the Special Collections of the University of St Andrews Library but were not utilized by Stone. James Forbes – not to be confused with the eminent marine biologist, Edward Forbes (1815–54), who succeeded Jameson to the chair of Natural History at the University of Edinburgh in 1854 – was, in the words of his biographer, Frank Cunningham (1990), a ‘pioneer Scottish glaciologist’. Forbes attended Jameson’s lecture course in Natural History at the University of Edinburgh in session 1827–28 and repeated the class in 1828–29. Forbes’ notes provide a valuable complement to those cited by Stone. Cunningham (1990, p. 14) records that, on the basis of Forbes’ notes, Jameson ‘treated his students to a thoroughly Wernerian version of geology’. Forbes’ notes also provide additional constraint to the timing deduced by Stone for Jameson’s conversion; he was a thoroughly Wernerian Neptunist in 1828 but a convert to Plutonism by 1830. With regard to glaciation, Forbes records in his notes from Jameson’s lecture 12 on 27 November 1827:","PeriodicalId":49556,"journal":{"name":"Scottish Journal of Geology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1144/sjg2020-022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49284027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
