Poorly preserved radiolarians of early Late Cretaceous age have been recovered from International Ocean Discovery Program (IODP) Hole U1520C, which was drilled as part of IODP Expedition 375 (Hikurangi Subduction Margin Coring, Logging, and Observatories). Seven radiolarian-rich samples from Cores 375-U1520C-42R and 43R (1027.8–1037.5 meters below seafloor) contain a relatively uniform assemblage that includes species indicative of a middle Cenomanian age (~97 Ma).

Data report: radiolarians from the latest Cenomanian and Turonian, Holes U1512A and U1516C, IODP Expedition 369
A total of 47 samples from the Albian to Turonian at three sites from International Ocean Discovery Program (IODP) Expedition 369 were investigated for radiolarian faunas. With a few exceptions, the preservation of radiolarian tests did not allow for a taxonomically sophisticated and proper determination. Consequently, radiolarian assemblages from only three samples from the uppermost Cenomanian in Hole U1516C, the lower Turonian in Hole U1516C, and the upper Turonian in Hole U1512A are described and illustrated here. The three faunas described include faunal elements reported from time equivalent successions in the Tethys as well as the western Pacific.

Because the western equatorial Pacific Ocean is famous for its calcareous oozes, various biostratigraphic studies on planktonic foraminifers and calcareous nannofossils have been conducted in this region. As a result, western equatorial Pacific Ocean–based studies have established that the tropical Pacific region drives the atmospheric circulation by high seawater temperature, strongly influencing the global climate. Based on this finding, a number of sites were cored in this region during International Ocean Discovery Program (IODP) Expedition 363. Shipboard results unexpectedly revealed that radiolarians are abundant and well preserved in sediment from Eauripik Rise Site U1490 between 220 and 350 m core depth below seafloor, Method A (CSF-A), within an interval of calcareous ooze composed primarily of calcareous nannofossils and foraminifers. Paleomagnetic reversal event and calcareous nannofossil and planktonic foraminiferal bioevents suggested that the interval from 220 to 350 m CSF-A corresponded to the Middle to Early Miocene. This study investigated radiolarian assemblages and the biostratigraphy of core catcher samples obtained from Hole U1490A between 250 and 350 m CSF-A. Notably, the last occurrence (LO) of Artophormis gracilis (Riedel) was confirmed at ~338 m CSF-A, demonstrating that the base of the site is older than 22.6 Ma in age. Additionally, the first occurrence (16.9 Ma) and LO (13.9 Ma) of Calocyclas costata Riedel were identified at 246.7 and 227.8 m CSF-A, respectively, and the LO of Didymocyrtis prismatica (Haeckel), indicating an age of 17.7 Ma, was recorded at 258.5 m CSF-A. We also calculate preliminary sedimentation rates based on the Early Miocene radiolarian biostratigraphy and provide taxonomic notes on radiolarian species.more » « less

The “mid-Cretaceous” (~125–80 Ma) was punctuated by major plate-tectonic upheavals resulting in widespread volcanism, mountain-building, eustatic sea-level changes, and climatic shifts that together had a profound impact on terrestrial biotic assemblages. Paleontological evidence suggests terrestrial ecosystems underwent a major restructuring during this interval, yet the pace and pattern are poorly constrained. Current impediments to piecing together the geologic and biological history of the “mid-Cretaceous” include a relative paucity of terrestrial outcrop stemming from this time interval, coupled with a historical understudy of fragmentary strata. In the Western Interior of North America, sedimentary strata of the Turonian–Santonian stages are emerging as key sources of data for refining the timing of ecosystem transformation during the transition from the late-Early to early-Late Cretaceous. In particular, the Moreno Hill Formation (Zuni Basin, New Mexico) is especially important for detailing the timing of the rise of iconic Late Cretaceous vertebrate faunas. This study presents the first systematic geochronological framework for key strata within the Moreno Hill Formation. Based on the double-dating of (U-Pb) detrital zircons, via CA-TIMS and LA-ICP-MS, we interpret two distinct depositional phases of the Moreno Hill Formation (initial deposition after 90.9 Ma (middle Turonian) and subsequent deposition after 88.6 Ma (early Coniacian)), younger than previously postulated based on correlations with marine biostratigraphy. Sediment and the co-occurring youthful subset of zircons are sourced from the southwestern Cordilleran Arc and Mogollon Highlands, which fed into the landward portion of the Gallup Delta (the Moreno Hill Formation) via northeasterly flowing channel complexes. This work greatly strengthens linkages to other early Late Cretaceous strata across the Western Interior.more » « less

A new latest Paleocene mammal fauna from the Great Divide Basin in southern Wyoming is described and compared with fossil assemblages of similar age elsewhere in Wyoming. The Twelvemile Gulch local fauna is currently documented by 182 mammalian (127 identifiable) specimens from two localities representing 10 orders, 18 families, and 22 species of mammals, including Phenacolemur cavatus, new species. Several characteristic taxa indicate a Clarkforkian age, but some taxa that co-occur at Twelvemile Gulch show disjunct stratigraphic ranges in the well-documented stratigraphic sequence exposed in the Clarks Fork Basin of northern Wyoming. Anachronistic occurrences of Clarkforkian taxa in northern and southern Wyoming have now been documented repeatedly. These unexpected faunal associations likely reflect changing climates and associated taxon-specific range shifts across a latitudinal gradient in the Rocky Mountain Interior. The apparently asynchronous first and last appearances of certain taxa across this latitudinal gradient highlight the utility of immigrant clades over endemic taxa in biostratigraphy. A previous biozonation scheme for the Clarkforkian of the Clarks Fork Basin emphasized endemic Plesiadapis cookei and Copecion as index taxa for Clarkforkian biozones Cf-2 and Cf-3, respectively. However, the applicability of this zonation to Clarkforkian faunas from other parts of Wyoming has been problematic because Plesiadapis cookei occurs in all of them, despite substantial evidence for age disparity among these faunas. A revised biozonation for the Clarkforkian leverages first appearances of invasive Coryphodontidae and Miacidae to discriminate later Clarkforkian faunas including Twelvemile Gulch from earlier Clarkforkian faunas such as Big Multi Quarry.more » « less

Xu, Jianping (Ed.)ABSTRACT Mitochondria originated from an ancient bacterial endosymbiont that underwent reductive evolution by gene loss and endosymbiont gene transfer to the nuclear genome. The diversity of mitochondrial genomes published to date has revealed that gene loss and transfer processes are ongoing in many lineages. Most well-studied eukaryotic lineages are represented in mitochondrial genome databases, except for the superphylum Retaria—the lineage comprising Foraminifera and Radiolaria. Using single-cell approaches, we determined two complete mitochondrial genomes of Foraminifera and two nearly complete mitochondrial genomes of radiolarians. We report the complete coding content of an additional 14 foram species. We show that foraminiferan and radiolarian mitochondrial genomes contain a nearly fully overlapping but reduced mitochondrial gene complement compared to other sequenced rhizarians. In contrast to animals and fungi, many protists encode a diverse set of proteins on their mitochondrial genomes, including several ribosomal genes; however, some aerobic eukaryotic lineages (euglenids, myzozoans, and chlamydomonas-like algae) have reduced mitochondrial gene content and lack all ribosomal genes. Similar to these reduced outliers, we show that retarian mitochondrial genomes lack ribosomal protein and tRNA genes, contain truncated and divergent small and large rRNA genes, and contain only 14 or 15 protein-coding genes, including nad1 , - 3 , - 4 , - 4L , - 5 , and - 7 , cob , cox1 , - 2 , and - 3 , and atp1 , - 6 , and - 9 , with forams and radiolarians additionally carrying nad2 and nad6 , respectively. In radiolarian mitogenomes, a noncanonical genetic code was identified in which all three stop codons encode amino acids. Collectively, these results add to our understanding of mitochondrial genome evolution and fill in one of the last major gaps in mitochondrial sequence databases. IMPORTANCE We present the reduced mitochondrial genomes of Retaria, the rhizarian lineage comprising the phyla Foraminifera and Radiolaria. By applying single-cell genomic approaches, we found that foraminiferan and radiolarian mitochondrial genomes contain an overlapping but reduced mitochondrial gene complement compared to other sequenced rhizarians. An alternative genetic code was identified in radiolarian mitogenomes in which all three stop codons encode amino acids. Collectively, these results shed light on the divergent nature of the mitochondrial genomes from an ecologically important group, warranting further questions into the biological underpinnings of gene content variability and genetic code variation between mitochondrial genomes.more » « less
