Climate doesn't happen in isolation. Case in point, the Miocene aridification of North Africa and the intensification of the South Asian Monsoon were actually connected processes. 🧪

Schematic illustration of the monsoon-desert mechanism at different stages of South Asian Monsoon (SAM) development. (A) Present day, (B) the middle stage (i.e., Miocene), and (C) the early stage (i.e., Eocene). Yellow shading indicates arid regions, while green shading denotes monsoon regions. White clouds highlight regions of climatological intense convection and heavy precipitation. The vertical panels depict the associated upper-tropospheric high-pressure anomaly. Dashed blue arrows mark the large-scale circulation (the upper troposphere is an anticyclone circulation), with arrow size reflecting intensity. The color stars indicate the poleward shift of SAM precipitation.

These ghost bats (Macroderma gigas) are ghosts in another way:

They're phylogenetic relicts whose lineage traces back to radiations in the Miocene & Pliocene. Their closest living relatives are in India & we know they once ranged across Australia.

Now you know about some ghost bats! 🎃

The cover image shows a Miocene flower of Ayenia sect. Vahihara (Malvaceae) preserved in amber and its reconstruction based on X-ray tomography data. This provides evidence of lianas in a Miocene rainforest in southeast China, and reveals a morphological stasis in floral structure within a tropical liana lineage since at least ∽14.7 million years ago.

Anatomical Atlas and Three-Dimensional Musculoskeletal Model of the Flight Apparatus in the Southern Screamer (Anseriformes: Chauna torquata)

#science #fossils #avian #birds
The three bird species within the family Anhimidae (screamers) are of great interest to the big picture of avian evolution due to both their #phylogenetic position and their unusual combination of features. As screamers are early diverging members of Anseriformes (#waterfowl), which itself is an early diverging clade within the extant bird radiation, their anatomy may help shed light on that of the common ancestor of both Anseriformes and crown-group birds as a whole. To reveal new information about the wing anatomy of anhimids, we generated a three-dimensional musculoskeletal model of the flight apparatus of the extant Southern Screamer (Chauna torquata) using diffusible iodine-based contrast-enhanced computed #tomography (#diceCT). We found that the wing muscle anatomy of Chauna reflects the soaring flight style employed by anhimids, as opposed to the rapid continuous wingbeats used by most other #anseriforms. In Chauna, this manifests as a more distal insertion of the pectoralis muscle on the humerus to facilitate slower, stronger wingbeats, and a reduction in the length of antebrachial muscle origins and insertions that serves to reduce the distal inertia of the wing. Our three-dimensional dataset represents a typical musculoskeletal system of a bird with strong flight capabilities. This, combined with our observation that most flight-related muscles in Chauna leave recognizable #osteological correlates associated with their attachments to the skeleton, means that this work can help form a basis for future comparative studies of the #avian #musculoskeletal system, with implications for reconstructing the flight apparatus of #fossil #birds.

Though the Elderfolk are eternal, the rest of the flora and fauna is not, with a cutoff in the late Miocene, 8 million year ago, for anything not a hominin. But evolution has continued here in the Enclosure. It's not just Elderfolk who get a second chance. 🧵 1/3

Hello, friends and #OctoberWorldbuilders! Today is a super open-answer day: What's something unique or special about your world? I don't mean it has to be something that has NEVER been done before, but maybe it's more rare than the usual tropes. Something that sets your work apart from many others.

It took about 15 million years for the ecosystem to go from the 450-500 ppm of CO2 in the Miocene to the preindustrial concentration of about 280 ppm. If we find ourselves in the Miocene, we’ll be stuck there for at least a few million years.

Welcome to the Miocene. Will We Survive?
The increasing CO2 concentration in the atmosphere has unbalanced the Earth system to the point that it is now how it was 10-20 million years ago, during the Miocene period.

A quick exercise in tracing soft tissue over an extinct mammal’s skull, here using Syndyoceras cooki, one of many very strange ungulates in the family Protoceratidae. It is unknown if they are closer to ruminants or camels, and their nasal openings are weird. #cenozoic #miocene #prehistoric #sketch
Two images, one above the other. On top is an old photograph of a skull of the extinct hoofed mammal Syndyoceras cooki, with a slender snout and two pairs of tall, curled ossicones above the snout and above the eyes. On the bottom is a quick black-and-white pencil sketch of how this animal may have looked in life, traced directly over the skull photo above. The snout and lips are long and llama-like, the head is overall quite narrow, the ossicones are covered in skin, and the ears are large and pointed. Both photo and drawing are facing towards the left. The same drawing and photograph as in the previous image, but with the drawing at 70% opacity layered over the photo to more clearly visualize how I’ve depicted the soft tissues around the bone.
