Mixosaurus cornalianus here was a small early ichthyosaur, only about 0.8-1m long (2'7"-3'3") and generally considered to be transitional between the eel-like swimming style of basal forms and the more dolphin-like later forms. Living during the Middle Triassic, about 242 million years ago, it inhabited a shallow tropical sea that covered what is now the modern border between Switzerland and Italy.

It was previously thought to be a slow swimmer with a low and poorly-developed tail fin, and whether it even had a dorsal fin or not was unclear. But now new specimens with soft tissue impressions have given us a big surprise.

Not only did it actually have a fairly well-developed semilunate tail fin, but it also had a dorsal fin positioned much further forward on its body than expected, giving it a shape similar to some small sharks and representing the current earliest known dorsal fin of any amniote.

Bundles of stiffening collagen fibers inside its fins were very similar to those known from later Jurassic ichthyosaur species, indicating that this adaptation evolved much earlier in the lineage than previously thought. Along with stomach contents showing it mainly ate both cephalopods and small fish – fairly fast-moving prey – this suggests it was a capable open-water swimmer. It wouldn't have been quite as speedy as its much more specialized Jurassic relatives, but it may have still been about as efficient as the small modern sharks it resembled.

Dov’è l’imene?

-------------------------------------------------------------

Oddio... è una domanda trabocchetto?  0_____0

Purtroppo non posso postare immagini, nemmeno di tavole anatomiche, perché il censorbot di tumblr me le flaggherebbe subito però posso farti un disegno di una vagina con l’imene ancora integro e di una con l’imene lacerato:

L’imene è una membrana a doppia semiluna che origina dalle pareti laterali del primo tratto della vagina, pochi millimetri dopo le piccole labbra e appena sotto il meato uretrale.

La sua elasticità e il fatto che le due semilune sia sufficientemente distanti fra loro permettono il passaggio del sangue mestruale e del materiale di sfaldamento dell’endometrio ed entro certi limiti e con granze perizia da parte dell’operatore, anche l’inserimento dello speculum per l’esame vaginale (che dovrà essere di un tipo particolare detto ‘per vergini’).

Forma, spessore e aspetto variano grandemente da una donna all’altra, fino ad arrivare anche alla sua assenza.

L’imene sembra avere una funzione protettiva da aggressione microbiche nella giovane femmina e sempre in base alla sua morfologia può succedere che si dilati senza lacerarsi al primo rapporto sessuale o che si laceri o si ritiri in modo spontaneo senza alcuna penetrazione.

Il cosiddetto cherrypopping costituisce quindi un mito tutto maschile di presunta purezza e illibatezza che oltre a essere stupido e offensivo dal punto di vista morale etico umano è pure idiota da quello anatomico.

Con calma, senza fretta e, soprattutto, senza cedere a imposizioni se non si è a proprio agio.

When the pansies withdraw into the earth I want to go too, want their stems to braid into my brachial plexus. I want the neophyte physicians to look at the fibrous semilunes on my chest and the mercury glass shells around my muscles

the sun slopes, spills blood-yolk on untouched, pristine snows (and I’ve read rainfall in the bones, I’ve read a scent like sage, like black frankincense, like the mouth of the angel Matariel, semilune and aching on the hill of my throat) and you leave your boots by the door, shake winter from your greatcoat, from your hair, muss up your smile, your come-hither eyes, crow’s feet folding in on themselves around the curl of your lashes, lashes like coal that have again and again kissed my cheeks, their ruddy apple orchards oh, how lovely that you’ve come hungry, how lovely that you’ve brought your dusk to my little kingdom of garlic, of lindens — how lovely that you’ve brought the heat of your tongue, electric where it cleaves, scattering fulgurites in the channel of my spine

u can really tell i ran out of steam writing this essay bc i wrote a ton abt the evolution of feathers like vaned vs downy, symmetric vs asymmetric vanes, etc and then when i got to the last bit i could barely write a paragraph like . birds have uhhhhhhh weird wrists?? so the... semilunate carpals like... make their arms fold like a wing... something something aerodynamics

I’m completely shocked. That one ultra sweet, well written fanfiction that I have been reading again and again since the release of 4.56 got updated twice (!) within the last 48 hours. And it’s soooooooooo good...

I just love it so much! I mean, the author has nailed all the characters. The romance is a slow burn, that’s hitting the sweet spot just between “I know they’ll get together” and “oh don’t tease me, this will never work”. I could never hope to write Ser Aymeric even half as well as she does (or even the other Ishgardian characters. All the new words I’ve learned!)

It’s been ages since I got star struck like this by a fanfiction. I’m so happy >>>.<<<

If anyone is interested: it’s called “Astral Fire, Umbral Heart” by The Rose Mistress (Semilune) on AO3. (I’m not sure if I’m allowed to link it, since it’s not my own story <.<)

Juvenile whale sharks have a tail fin with a larger upper lobe than lower. In adults the tail becomes semilunate.

I've seen a lot of Paleoart of raptors and other feathered dinosaurs that have their wings down at their sides instead of folded. Do you know if raptors could fold their wings or if they just had them hanging at their sides?

They could fold their wings to some degree, thanks to a bone called the “semilunate carpal” that allowed this swivelling of the wrist. Matt Martyniuk has written an excellent blog post about this, so I’ll just link his instead of repeating all of his points.

kiss me;

until there is blood

searing shut the semilune

of our joined mouths.

kiss me; with lips, with eyes, with body whole, heart humming my name.

kiss me; until the boundary separating our shadows has turned to smoke.

kiss me;

with deep abandon,

without doubt, aflower

in my quiet breath.

Are Zhou & Martin’s (1999) “uniquely avian” manual characters known in any other theropods?

Given the focus of Zhou and Martin’s paper, I’ll assume you’re asking about theropods potentially stemward of Archaeopteryx.

A semilunate carpal centered on second metacarpal is also found in Sinornithosaurus, Microraptor, Graciliraptor, and Anchiornis.

A ventrally slanted third metacarpal is also found in Deinonychus (noted in Gishlick’s chapter in New Perspectives on the Origin and Early Evolution of Birds), and it wouldn’t surprise me if it was widespread in tetanurans, given that the third metacarpal overall tends to be positioned ventrally to the second metacarpal within that group.

Four carpals forming a similar arrangement to those of modern birds have also been found in Microraptor and probably Hagryphus.

Simplified articulations between the metacarpals and phalanges are also found in some ornithomimosaurs (e.g., Anserimimus) and scansoriopterygids, and if only the third metacarpal is considered, are common among maniraptoriforms.

The second metacarpal being more robust than the others is also found in some oviraptorosaurs (e.g., caenagnathids), microraptorians, and anchiornithines.

A rounded proximal end of the first metacarpal might actually be limited to avialans, as far as I can tell, but whether it’s really found in Archaeopteryx looks ambiguous to me.

A ridge on the first phalanx of second finger is also found in Sinornithosaurus (noted by Paul in Dinosaurs of the Air) and Deinonychus. I don’t recall any non-avialan theropods in which this has been reported on the second phalanx as well, but it’s far from clear to me that it’s present in Archaeopteryx either.

The distal end of first phalanx of second digit being as wide as or slightly wider than proximal end seems to be pretty common among maniraptoriforms.
