Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

Conservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Hyænodontidæ of the Upper Eocene of California [PDF]

Proceedings of the National Academy of Sciences, 1933
Since the announcement(1) of the discovery of upper Eocene mammals in the Sespe deposits north of the Simi Valley, California, excavations have been continued in these beds, particularly at Locality 150 C. I. T. Vert. Pale., by field parties of the California Institute.

Geochemical expression of early diagenesis in middle Eocene-lower Oligocene pelagic sediments in the Southern Labrador Sea, Site 647, ODP Leg 105

, 1989
Geochemical analyses of the middle Eocene through lower Oligocene lithologic Unit IIIC (260-518 meters below sea floor [mbsf]) indicate a relatively constant geochemical composition of the detrital fraction throughout this depositional interval at Ocean ...

Time‐calibrated relationships of a rare cave catfish (Trichomycterus rubbioli): Shedding light on troglobitic lifestyle origin in the Brazilian caatinga

Journal of Fish Biology, EarlyView.
Abstract Catfishes of the subfamily Trichomycterinae comprise the most diverse fish group with species adapted to live in Neotropical caves, but past evolutionary scenarios that have driven the origin of these troglobitic species remain unknown. We herein investigate the phylogenetic position of the cave‐restricted Trichomycterus rubbioli, endemic to ...

Eocene-Oligocene mass accumulation rates of ODP Site 124-707

, 1991
Oceanic crust at Sites 767 and 770 in the northern Celebes Sea is overlain by Eocene and Oligocene pelagic sediments. Brown clay accumulated below the calcite compensation depth (CCD) at the deeper Site 767 throughout this time interval. At the shallower

Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

Pangenome analysis reveals the genetic mechanism underlying high‐altitude adaptation in Qinghai–Xizang (Tibet) Plateau Rhododendron

Journal of Integrative Plant Biology, EarlyView.
Pan‐genome analysis reveals that high‐altitude Rhododendron species resist alpine cold stress by rapidly sensing and engaging the chilling response pathway and genes that directly and indirectly protect the plant from UV radiation. Heritable genomic features such as long terminal repeats contribute to the adaptive diversification of Rhododendron ...

An Eocene Primate from California [PDF]

Proceedings of the National Academy of Sciences, 1933
Recognition of a primate in the mammalian assemblage now being recorded from one of the faunal stages of the Sespe, north of the Simi Valley, California, comes with startling abruptness, yet is not wholly unexpected. No fewer than five fragments of jaws, probably representing as many individuals, have been found recently.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

Journal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Love in the Eocene

Emic
My submission showcases the research I've gathered while working in the Paleobotany sector of Florida's Natural History Museum. A key aspect of my work includes imaging fossils from the Eocene period, which date back millions of years. This fossil fragment, resembling a heart, symbolizes the enduring nature of love through Earth's history.
