At the Mannum Pumping Station section, the Finniss Clay fauna has a low diversity, frequent shallow-water forms, and a poor taphonomic grade. In what was the deeper part of the basin at Waikerie, a diverse fauna with well-preserved small species is recorded in sediments equivalent to the Finniss Clay. In contrast, the Cadell Marl from various localities comprises a well-preserved and diverse biofacies with both shallow and deeper water taxa. These contrasts suggest different depositional environments: shallower and warm during deposition of the Finniss Clay and nutrient-rich, dysaerobic and deeper water during deposition of the Cadell Marl. The shallowing event indicated by faunas from the Finniss Clay was due to falling sea level close to the early/middle Miocene boundary, whereas the Cadell ...","PeriodicalId":50830,"journal":{"name":"Alcheringa","volume":"23 1","pages":"133-152"},"PeriodicalIF":1.3,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03115519908619326","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59989502","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}

Synaustrus is most closely related to Euthycarcinus. New morphological findings and interpretations (e.g., a slender seta on each leg annulation; a series of articulated cephalic sternites) confirm the similarity of Synaustrus to other euthycarcinoid taxa. The evidence presented here allies euthycarcinoids with atelocerates, but they cannot be positioned higher than the stem-lineage of Atelocerata. Synaustrus and other genera possess trunk apodemes analogous to those of symphylans. Sternal pores in euthycarcinoids resemble coxal vesicles, though this conflicts with other morphological indications of aquatic habits.","PeriodicalId":50830,"journal":{"name":"Alcheringa","volume":"23 1","pages":"193-213"},"PeriodicalIF":1.3,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/03115519908619516","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59990383","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 is particularly evident in anterior bones, making definition of these bones difficult, and creating problems for phylogenetic analyses. Despite a close association of the sensory lines with the bones of the developing skull in the Australian lungfish, Neoceratodus forsteri, few traces of the lines remain in the bones of the adult animal. Among derived dipnoans, Mioceratodus, a genus of neoceratodont fossil lungfish from Tertiary deposits in central and northern Australia, is unusual because traces of the supraorbital sensory line are retained in the anterior skull roofing bones of large specimens. Equivalent traces are absent from the rostral bones of N. forsteri, and from small specimens of Mioceratodus.

The distinctive acritarchs Cerebrosphaera buickii, Satka colonialica, Stictosphaeridium sinapticuliferum and Pterospermopsimorpha insolita are of particular interest in the Neoproterozoic.
