These burrows are covered with tests of Nummulites cf. praelyelli and Nummulites deshayesi. The studied traces most closely resemble morphotype C of N. eocenica from the Eocene of the Tatra Mountains. The Iranian specimens occur in marly limestone that was deposited in a moderate to low energy environment on the shallow part of a ramp, although occasionally sediments indicate wave action and storm influence in high-energy conditions. The trace maker may have selectively used microspheric forms or B-forms of Nummulites by means of its appendages. Moreover, A-forms are dominant in accumulations of foraminifera in the studied section, but the trace maker obviously preferred the thinner test B-forms that are mainly saddle and flat shaped forms (Nummulites cf. praelyelli) over the lenticular and thick test forms (e.g. N. deshayesi). In addition to the protection against the episodic hydrodynamic activity, it is possible that one of the main reasons behind the reinforcement of burrow walls may have been the need for protection against predators. The trace makers were likely crustaceans or alternatively onuphid polychaetes.","PeriodicalId":48706,"journal":{"name":"Palaeobiodiversity and Palaeoenvironments","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142221959","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 Eocene Green River Formation lagerstätten, exceptionally preserved fossil deposits, provides an opportunity to examine the role of microbial communities and their metabolic byproducts, such as chemical precipitated in this spectacularly preserved fish deposit, famous throughout the world. Field emission scanning electron microscope (FESEM) and energy dispersive spectroscopy system (EDS) examination of a well-preserved Knightia eocaena from the Eocene Green River Formation documents the presence of bacteriomorphs. Bacteriomorphs in a sample from the Fossil Butte Member of the Green River Formation consists of spherical structures, coccoid-type bacteria, fibres from two-sized populations of filamentous bacteria, probable filamentous cyanobacteria, capsule-shaped, and bacilliform bacteria, all associated with framboidal iron hydroxide.Bacteriomorphs consist of external molds composed of nanometer-scale calcium carbonate spheres. Fe-oxide framboids have an amorphous exterior and a sieve-like internal structure. The sieve-like structure consists of nanometer-scale pores, probable sites of bacterial cells with walls composed of 100-nanometer-scale spheres. Fe-oxides are consistent with bacterially mediated precipitation of pyrite followed by an oxidation event. Preserved bacteriomorphs are consistent with degradation of soft tissue, limiting the preservation of soft tissue and leaving bone and scales with no appreciable soft tissue. The microfossils are restricted to the skeleton and are not found in the surrounding rock matrix, suggesting larger microbial mats may not have been present and possibly did not have a significant impact on the preservation of this specimen.","PeriodicalId":48706,"journal":{"name":"Palaeobiodiversity and Palaeoenvironments","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142221957","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}

These jaws collectively provide considerable data on the morphology of the maxilla, dentary, teeth, coronoid, splenial, angular, surangular and prearticular. All six jaws can be unequivocally allocated to Lacertidae and five of those are allocated to European green lizards of the Lacerta viridis group. Currently, La. viridis has regionally extinct or probably extinct status in Poland. The material from Węże I provides evidence that European green lizards had a large geographic distribution in Europe, including Poland during the ?Pliocene. One mandible fragment appears to be slightly different and is allocated to Lacertidae indet. That mandible might point to a higher taxonomic diversity of lacertids in this locality. However, that interpretation needs to be viewed with caution, because based on such limited material, individual and/or ontogenetic variation cannot be ruled out. To reveal the real taxonomic palaeodiversity of lacertids in Węże I, new and more complete cranial material is needed. In addition, this article provides insights into the comparative osteology of skulls and selected cranial elements in lacertids.","PeriodicalId":48706,"journal":{"name":"Palaeobiodiversity and Palaeoenvironments","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937782","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}

Carboniferous echinoid faunas feature distinct and specialised groups compared to those of the Devonian, suggesting important evolutionary changes during the Late Devonian, although the role of biotic crises like the Kellwasser and Hangenberg Events in these changes remains poorly known. This study describes an exceptionally well-preserved echinoid fauna from the middle to upper Famennian of Velbert near Düsseldorf, Germany. Description of six new species belonging to the lepidocentrid, hyattechinid, proterocidarid and archaeocidarid lineages along with a seventh species based on isolated remains greatly add to the knowledge of Late Devonian echinoids. The newly described genera Thielechinus gen. nov. and Velbertechinus gen. nov. represent the most derived proterocidarids and archaeocidarids known from the pre-Carboniferous. Moreover, the fossils offer new insights into phylogeny, ontogeny, and palaeobiology of several stem-group echinoid lineages. The fauna resembles Carboniferous echinoid faunas much more than earlier Devonian faunas, thus providing evidence that crucial developments had occurred from the Frasnian to the Famennian, possibly linked to global changes associated with the catastrophic Kellwasser Event. These developments include the appearance of several specialised lineages that would become important in the Late Palaeozoic as well as evolutionary innovations leading up to the establishment of the crown-group echinoid body plan.","PeriodicalId":48706,"journal":{"name":"Palaeobiodiversity and Palaeoenvironments","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141782911","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}

To gain insights into the plant-insect interaction during the Middle Jurassic in western Liaoning, this paper aims to identify and quantitatively analyse evidence of insect damages on fossil leaves from the Haifanggou Formation based on previous taxonomic research. Seven insect damage types (DTs) assigned to three functional feeding groups (FFGs) are identified. Margin feeding is the most prevalent FFG, followed by hole feeding and surface feeding, suggesting that Orthoptera and Hymenoptera with chewing mouthparts were dominant during the Middle Jurassic in this area, with Hemiptera and Coleoptera also playing a significant role. The primary plant groups targeted by insects are Ginkgophytes, followed by Pteridophytes, Cycadophytes and Czekanowskiales, with Cycadophytes exhibiting the highest average percentage of damaged leaf perimeter and area. This could be attributed to the physical insect resistance mechanism of conifers, as well as the chemical defense capabilities of Pteridophytes and Ginkgophytes during the Middle Jurassic. Plants and insects from the Haifanggou Formation are highly diverse, and approximately 17.54% of the observed fossil leaves show traces of insect damage, probably indicating the presence of active insects in the area and a close relationship between plants and insects during the Middle Jurassic. Considering the floristic composition and the climate-indicative plant groups, it can be inferred that the climate in the study area during the Middle Jurassic was warm and humid, potentially accompanied by intermittent droughts.","PeriodicalId":48706,"journal":{"name":"Palaeobiodiversity and Palaeoenvironments","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744838","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}
