The fossil record of arborescent lignophytes shows an increasing anatomical diversity during the Tournaisian (360-347 Mya), suggesting a morpho-anatomical diversification following the extinction of the progymnosperm Archaeopteris Dawson, 1871 at the Devonian-Carboniferous boundary. This view has been partly constructed on recent investigations of Early Carboniferous deposits in eastern Australia. In this paper, we describe new silicified wood remains from the Tournaisian of the Burdekin Basin, northeastern Queensland, Australia, that are anatomically close to the genera Pitus Zalessky, 1911 and Eristophyton Gordon, 1935. While uncertain, the taxonomic affinities of these wood remains have several implications for future studies of Early Carboniferous arborescent lignophytes. First, the taxonomy of Eristophyton and Pitus has become increasingly problematic as reports of fossil wood assigned to these genera have extended beyond Laurussia. Second, Eastern Gondwanan and Laurussian floras display a convergent pattern of diversification from the Devonian, with the probable presence of a diversity of lignophyte trees in the Early Carboniferous. Third, convergence between Laurussia and Australia with respect to wood anatomy and discrete growth rings may be consistent with past suggestions of a monsoonal circulation during the Early Carboniferous.

In the palaeogeographical context of the opening of the South Atlantic Ocean at the end of the Early Cretaceous, we document here the first microvertebrate fauna recorded from the Aptian deposits of Gadoufaoua, Niger. A systematic study of the fauna has resulted in a significant expansion of the existing faunal list and increase our knowledge of the palaeobiodiversity of the Gadoufaoua fossil site. Some taxa were previously recorded (lungfishes, crocodilians, chelonians, etc.), but several new taxa are described here for the first time, including the first occurrence of a stem-boreosphenidan mammal in Africa for this time-interval. In addition, chondrichthyans, pterosaurs and lissamphibians are documented. The analysis of taxonomic diversity and preservation of the fossils confirms a floodplain depositional environment (more precisely channel-type), in a higher velocity flow regime than previously thought based on studies of the macrofauna. To confirm the depositional environment inferred by the state of preservation of the fossils, a preliminary comparison with the fauna of similar age from the Santana Formation (Brazil) has been undertaken. The hypothesis of a communication between Africa and South America during the Aptian, as had already been demonstrated based on studies of the macrofauna, is strengthened.

The occurrence of the genus Prolagus Pomel, 1853, in North Africa provides some of the strongest evidence for the existence of faunal exchanges between Europe and Africa. The oldest African Prolagus remains have been reported from the Messinian locality of Afoud in the Aït Kandoula Basin (6.2 Ma), identified during previous studies as the species Prolagus michauxi López-Martínez, 1975. Dental material already analyzed from the AF12-1 and AF12-2 levels and new material collected subsequently from the same levels form the basis of the current systematic study. This abundant material allows us to confirm the presence of a single Prolagus species in the Afoud locality, P. michauxi. However, this species’ attribution to P. michauxi must be considered cautiously, given its evident morphological resemblance to Prolagus sorbinii Masini, 1989. These results are consistent with scenarios implying the migration of P. michauxi from Southern Europe to North Africa. In addition to the Prolagus remains, cheek teeth of Leporidae have been found and this is the oldest occurrence of this group in Morocco.

Here we describe new marine vertebrate remains, mainly isolated teeth, from the Upper Cretaceous (Coniacian-Santonian) of near Mardin, SE Turkey. This is the first report in this area of ptychodontid sharks (elasmobranchs), enchodontid teleosts (actinopterygians) and mosasaurid squamates (reptiles). The respective taxa Ptychodus cf. mortoni, Enchodus sp., Platecarpus sp. and Mosasaurinae indet. are described. These new data improve our knowledge on early Late Cretaceous marine vertebrate faunas from the Arabic Platform, classically known previously mostly from the Maastrichtian outcrops of Middle-East and Northwestern Africa, and extend the palaeobiogeographical distribution of these taxa into the western part of the Mediterranean Tethys, confirming their cosmopolitan status.

The fossil record of dipnoans is mostly represented by tooth plates and jaw bones, whereas nearly complete or complete skulls are rare. Here, we describe a new dipnoan from the Santonian (Upper Cretaceous) of Patagonia (Argentina) using three-dimensional renderings generated by CT scans. It consists of a near-complete skull and postcranial material. Rinconodus salvadori n. gen., n. sp. is diagnosed by a combination of features, such as medial series composed of two unpaired bones, mediolateral series composed of two paired bones, lateral series with at least one bone, medial edge of tooth plates longer than the lingual edge and equally curved, upper tooth plates contiguous or close to one another with five denticulations, lower tooth plates widely separated with four denticulations, first denticulation of upper tooth plates longer and thinner than the remaining denticulations, and posteriorly curved, first denticulation of lower tooth plates relatively straight and longer than the remaining ones, among other characters. The new species is based on the first two nearly complete Santonian dipnoan skulls from South America. Moreover, the materials presented here are the geologically youngest dipnoan remains consisting of a near-complete skull and postcranium from the Cretaceous of Gondwana.

We report the first cephalopod statoliths from the Early Cretaceous. These unique microfossils fill the gap in the fossil record between Jurassic and Cenozoic forms, and are more similar to the former. We compare the morphology of the Mesozoic forms with the statoliths from Recent and Cenozoic decabrachians. This comparison shows the closest resemblance to the Recent Idiosepiidae. We suggest that Mesozoic cephalopod statoliths belong to the basal decabrachians and they are related to the idiosepiids. The belemnitid identity of these forms can be neither confirmed nor rejected though some positive correlation in the investigated materials between findings of belemnitid rostra and statoliths do occur. These finds support also some previous suggestions that decabrachians and vampyropods diverged earlier than in the Early Jurassic. We discuss the absence of the wing in the Mesozoic statoliths and suggest that the robustly developed spur could play a similar role to the wing in Cenozoic and Recent decabrachian statoliths. We suggest that the statolith morphology might be a useful tool to interpret cephalopod evolution. We also note an evident shift in the abundance ratio of statoliths vs fish otoliths, the former being dominant in the Jurassic while declining in abundance in the Cretaceous. This supports a Cretaceous turnover in several groups of marine organisms.

The Isle of Crete contains an important endemic fossil fauna that has been studied extensively in the past. An endemic fossil tortoise, Testudo marginata cretensis Bachmayer, Brinkerink & Symeonidis, 1975, had previously been named from Pleistocene cave deposits in the island, presumably being larger than the mainland species and having some important morphological differences as well. In this paper I revise these type specimens and describe for the first time numerous additional fossil specimens from the Pleistocene sites of Gerani IV, Zourida, Koumpes, Liko, Mavro Mouri IV, and Simonelli Caves (near Herakleion), Rethymnon fissure, and from the open site of Sitia in the eastern part of the Island. These specimens belong mostly to the marginated tortoise, but the presence of a terrapin is confirmed as well. These new fossils help to refute the validity of the Cretan subspecies, and change the range of the marginated tortoise during Pleistocene/Holocene times in the southern Balkans.

Ordovician conodont collections from several Argentinian basins including the Eastern Cordillera, Famatina and Precordillera allow recognition of a group of conodonts that comprise a new genus here named Condorodus n. gen. Species of this genus have an apparatus composed of six elements recovered so far: Pa, Pb, Sb1, Sb2, Sc and Sd. The differences mainly between the P elements support recognizing three species, from the older to younger: C. diablensis n. gen., n. sp., C. gracielae n. gen., n. sp. and C. chilcaensis n. gen., n. sp., that appeared in the upper Floian (Lower Ordovician) and vanished in middle Darriwilian time (Middle Ordovician). The Eastern Cordillera is here assumed as the place of origin of the Condorodus n. gen. lineage during the late Floian, and then this genus dispersed through the western margin of Gondwana, reaching the Precordillera in the early Darriwilian, from there it could have dispersed to different regions of Gondwana, Perigondwana and Laurentia during the late Darriwilian, and probably give rise to conodont apparatuses of similar morphology in the Late Ordovician.
在包括东科迪勒拉、法马蒂纳和前科迪勒拉在内的几个阿根廷盆地收集到的奥陶系牙形刺标本中，有一组牙形刺组成了一个新属，在这里被命名为Condorodus n. gen.这个属的物种有一个由六种元素组成的仪器:Pa、Pb、Sb1、Sb2、Sc和Sd。P元素之间的差异主要支持从老到新三个物种的识别:C. diablensis n. gen.， n. sp.， C. gracielae n. gen.， n. sp.和C. chilcaensis n. gen.， n. sp.，它们出现于上弗洛世(下奥陶统)，消失于中达里威廉世(中奥陶统)。在弗洛世晚期，东科迪勒拉被认为是Condorodus n. geng谱系的起源地，然后这个属通过冈瓦纳的西部边缘分散开来，在Darriwilian早期到达Precordillera，在Darriwilian晚期，它可能从那里分散到冈瓦纳、Perigondwana和Laurentia的不同地区，并可能在晚奥陶纪产生类似形态的牙形刺装置。

The Eastern Cordillera is here assumed as the place of origin of the Condorodus n. gen. lineage during the late Floian, and then this genus dispersed through the western margin of Gondwana, reaching the Precordillera in the early Darriwilian, from there it could have dispersed to different regions of Gondwana, Perigondwana and Laurentia during the late Darriwilian, and probably give rise to conodont apparatuses of similar morphology in the Late Ordovician.","PeriodicalId":51002,"journal":{"name":"Comptes Rendus Palevol","volume":"11 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75888043","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}
