Ever wondered what a cormorant’s heart looks like?🦆 A new study on Phalacrocorax brasilianus found it has some unique cardiac quirks—like a one-piece right valve and cartilage supporting the aortic base!

This Halloween, meet the real masters of the night! 🦇
This study by Quinn et al. shows that Seba’s short-tailed bats use tiny sensory hairs on their wings to fine-tune flight — changing wingbeat and shape mid-air!

When does the human notochord begin to degenerate? A new study by Makino & Yamada, which performs a morphological analysis across Carnegie Stages 13–23 shows shrinkage starts at CS 17–18 (≈39–45 days post-fertilization). ✨

🦎✨ Check out this new manuscript by Bothe & Fröbisch comparing axolotl and tiger salamander limb regeneration! Axolotls may be the gold standard in the lab, but tiger salamanders may prove a better model for bite-induced regeneration.

🦎 Early Pliocene fossils (4.2–3.2 Ma) from Megalo Emvolon, Greece reveal Varanus cf. marathonensis, likely atest record of this monitor lizard in Europe.
Morphology links it to Asian not African lineages (esp. V. flavescens)

New study tracks semicircular canal development. Rapid growth & shape change occur w/in postnatal week 1, stabilizing by day 14 as ossification completes. Brief but critical window of vestibular morphological plasticity

🦇 Bat nasal bones (turbinals) reveal how form follows function. Echolocating bats have simpler, plate-like turbinals, while fruit-eating bats show complex, scrolled ones—especially Cynopterus sphinx & Artibeus jamaicensis.

🚨 New research on Triassic fossils from Brazil!
Dicynodonts were key terrestrial vertebrates of the Permian–Triassic. New study reveals Dinodontosaurus brevirostris—previously known only from Argentina—also lived in Brazil

🦎 New study revises Czech baphetid fossils (Carboniferous stem-tetrapods).
Rediscovered type of Loxomma bohemicum = actually Capetus palustris
Remaining fossils = Baphetes orientalis
Phylogeny suggests Baphetinae may be polyphyletic

For centuries, anatomists debated true origin of levator veli palatini—vital for speech & swallowing. Researchers found it arises from cartilaginous Eustachian tube not petrous bone, reshaping understanding of vocal tract evolution
