Diplichnites cuithensis (and other Diplichnites species) commonly occur associated with the burrow Taenidium barretti . The latter is known to have been widespread globally throughout the Carboniferous, and is a common component of fluviatile sequences within the Lower Carboniferous succession of NW Ireland.

Here we describe a suite of new lungfish specimens collected from sites in the Scottish Central Coalfield that represent a least four taxa:\u0000 Sagenodus\u0000 ;\u0000 Conchopoma\u0000 ; and two new forms\u0000 Braccodus kerri\u0000 gen. et sp. nov and\u0000 Lanarkodus clarki\u0000 gen. et sp. nov. These are part of an extensive vertebrate fauna recently discovered in colliery waste from mining the Upper and Lower Drumgray Coal. These coals lie within the\u0000 Communis\u0000 Chronozone and are of Langsettian age. The specimens are much smaller than those found previously in the Scottish Coal Measures and represent fish between 60 and 300 mm long. The basihyal tooth plates of\u0000 Conchopoma\u0000 are the first record of this genus in the Pennsylvanian of Europe.\u0000 Lanarkodus clarki\u0000 has a heterodont dentition not previously described from the Pennsylvanian. All the new material is preserved in thin, laminated shales, suggesting a small lake environment rather than the typical coal swamp. These new discoveries demonstrate that Pennsylvanian lungfish were more diverse than previously realised and add to growing evidence that the rate of lungfish evolution did not decline significantly after the Devonian, and remained high throughout the Carboniferous.\u0000 \u0000 \u0000 Thematic collection:\u0000 This article is part of the The Palaeontology of Scotland collection available at:\u0000 https://www.lyellcollection.org/topic/collections/palaeontology-of-scotland\u0000","PeriodicalId":49556,"journal":{"name":"Scottish Journal of Geology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48803256","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}

Its metatarsal and caudal vertebrae are considerably larger than corresponding bones in the\u0000 Dearc\u0000 holotype, indicating that it belonged to an even larger individual, thus demonstrating that pterosaurs with broad wingspans were not anomalous in the Middle Jurassic.

In this study, mine water geothermal exploration has been coupled with ground investigation techniques to assess ground stability alongside seasonal mine water hydrogeology and geochemistry. Drilling operations in late 2020 at Dollar Colliery, Clackmannanshire, Scotland, encountered mined coal seams with varying conditions (void, intact, waste, etc.), reflecting different techniques used throughout a protracted mining history. We found that time and resources spent grouting casing through worked mine seams (ensuring hydraulic separation) can be saved by accessing deeper seams where those above are unworked. Continued assessment of existing water discharges and completion of boreholes with slotted liners into mined coal seams and fractured roof strata allowed chemical and water level changes to be monitored across a 1-year period. Mine water heads and mine discharge flow rates vary seasonally and are elevated between late autumn and early spring. The mine water has a low dissolved solute content. Dissolved sulphate-\u0000 34\u0000 S isotope data suggest increased pyrite oxidation during lower water levels. These findings can inform future building decisions, whereby housing developments on site could use the mine water for heating.\u0000 \u0000 \u0000 Thematic collection:\u0000 This article is part of the Early Career Research collection available at:\u0000 https://www.lyellcollection.org/topic/collections/early-career-research\u0000 \u0000 \u0000 Supplementary material:\u0000 https://doi.org/10.6084/m9.figshare.22188801\u0000","PeriodicalId":49556,"journal":{"name":"Scottish Journal of Geology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46739684","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}

The stone is identified on sedimentological and palaeontological evidence and historical context as Ordovician ‘orthoceratite limestone’ from Sweden, probably the island of Öland, rather than Carboniferous cephalopod limestone from the much nearer Closeburn area of Dumfriesshire. ‘Orthoceratite limestone’ was little used in Great Britain, and mainly as paving, so its use in a funerary monument is unusual. It is, however, paralleled by contemporary examples at Winchester Cathedral. The Penicuik slab was probably imported either directly from Sweden, or through Rotterdam or another Netherlands entrepôt. It is the only surviving historical example of this stone known in Edinburgh and the Lothians, probably because of changing fashions, building demolition and renewal of worn paving. The inscription shows errors of composition, carving and installation, ascribed to inexperience or haste. The employment of ‘orthoceratite limestone’ is interpreted as seeking to emulate Roman use of marbles and similar ornamental stones. It contributes to the Penicuik mausoleum's significance as a pioneering example of classical or Antique architecture.","PeriodicalId":49556,"journal":{"name":"Scottish Journal of Geology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49008697","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}
