Despite their scarcity, these tracks represent the only evidence extending the temporal range of non-avian theropods in the country back to the Early Jurassic. However, the available specimens are isolated, exhibit low anatomical fidelity, and are restricted to limited stratigraphic intervals. Here, I report two new track-bearing horizons from the middle–upper Callovian Khechem El Miit Member in the Tataouine Basin. The lower track-bearing layer (L1), which underlies a previously described trampled horizon designated here as L2, yields medium-sized tracks with morphological and morphometric features comparable to those of the ichnogenus <em>Grallator</em>. The upper track-bearing layer (L3) has yielded larger footprints that represent the largest theropod tracks ever recorded in Tunisia and are attributable to <em>Eubrontes</em>. These findings indicate that non-avian theropods had a broader stratigraphic and geographic distribution and were more persistently present in the Tataouine Basin throughout the Jurassic than previously recognized. Moreover, the new tracks provide additional insights into the diversity and palaeobiogeographical affinities of Middle Jurassic theropods in southern Tunisia.</div></div>","PeriodicalId":49672,"journal":{"name":"Proceedings of the Geologists Association","volume":"137 3","pages":"Article 101189"},"PeriodicalIF":1.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193587","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}

Facies analysis allowed for the identification of a range of depositional environments, spanning continental settings (subaerial collapse, torrential systems, fluvial systems, and floodplains), mixed zones (including a possible fan-delta within an estuarine basin), and fully coastal–marine contexts. The spatial and stratigraphical relationships among the terraces indicate that TT1 and TT2 form a stepped sequence attributable to the tectonic uplift of the Western High Atlas. In contrast, the normal stratigraphical transition from TT2 to TT3 suggests predominant eustatic control during a period of relative tectonic stability. The two transgressive events responsible for TT1 and TT3 are separated by a forced regression, materialised by the prograding fan-delta of TT2.

The latter scenario, or ‘pitfall theory’, grew to be favoured by Dawson and to be depicted in most texts on the history of life, but is here scrutinized following recent discoveries by the authors and re-evaluation of historic finds. Nominally eleven tetrapod taxa have been identified from the fossil trees, including the earliest known amniotes — the richest single Carboniferous record of terrestrial tetrapods. Tetrapods co-occur with detrivorous invertebrates (land snails and millipedes), as well as putative insects. Here, we systematically evaluate scenarios for the occurrence of the tetrapod fauna, including accidental entry (pitfall, being washed in); temporary, opportunistic use (by predator, as refuge from fire); and denning. These scenarios have been weighed against salient aspects of their taphonomy, including their entry prior to infilling, disassembled skeletons, and ubiquitous association with charcoal. The broader role of wildfire is suggested by discovery of a tetrapod-bearing lycopsid with notched, charred base consistent with a fire scar, the oldest such example in the fossil record. Of the scenarios scrutinized, the most parsimonious is that tetrapods utilized lycopsid hollows as dens; compelling analogues are found in tree hollow fauna of modern forest biomes, many of which use fire scars as entry. Temporal shifts to seasonal, fire-prone drylands may have exerted ecological pressure on the Joggins fauna to avail themselves of tree hollows whilst providing access <em>via</em> fire scars. The tetrapod fauna at Joggins, which includes the earliest amniote, records the earliest known example of the hollow tree guild, well adapted to the ecological dynamics of the ‘Coal Age’ landscape.</div></div>","PeriodicalId":49672,"journal":{"name":"Proceedings of the Geologists Association","volume":"137 2","pages":"Article 101177"},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147553910","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}

This paper aims for a precise and in-depth geometric-gitological description of the ore-bearing structures in the Aouli vein system (AVS), as well as their structural-palaeostress analysis and the tectonic–geodynamic setting of their emplacement. Geological mapping allowed identifying several fault-filling sulfide–barite veins cutting the Cambro-Ordovician metasediments and Triassic series. They extend over multi-kilometer length and are of meter to decimeter thickness. The structural analysis revealed two main directional systems for these veins: (i) NNE–SSW to NE–WS and (ii) ENE–WSW to E–W. The palaeostress fields associated with vein development and mineralisation emplacement are consistent with a pure extensive tectonic regime. The calculated palaeostress tensors indicate a NW–SE to N–S subhorizontal to horizontal σ3 axis and a subvertical σ1 axis with tectonic regime index R′ ranging from 0.27 to 0.43. The AVS is controlled by normal faults developed during extensional tectonic events resulting from the Atlasic–Central Atlantic–Tethys rifting stage during the Upper Triassic–Lower Liassic times in the north-western Gondwana margin. The trigger mechanisms for metallogenic processes are crustal thinning and the Central Atlantic Magmatic Province (CAMP) activity. At regional scale, these metallogenic events are related to the Pangea breakup, where the main process for the deposition of the major Mesozoic hydrothermal deposits was the Central Atlantic–Tethys–Caribbean rift system in North Africa and Western/Central Europe.</div></div>","PeriodicalId":49672,"journal":{"name":"Proceedings of the Geologists Association","volume":"137 2","pages":"Article 101175"},"PeriodicalIF":1.3,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147553913","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}
