How animals detect the Earth’s magnetic field remains a mystery in sensory biology. In a new Science study, researchers used whole brain activity mapping, tissue clearing, and light sheet microscopy to identify neuronal populations activated by magnetic stimuli in the pigeon.

A novel strategy to determine rough age in dinosaurs — counting rings in throat bones — shows that Nanotyrannus was a distinct tyrannosaur group. https://t.co/mpyf8TeFh1

Nanotyrannus wasn’t a juvenile T. rex but a petite adult of a separate species, a new study of fossil hyoid bones finds, bolstering a recent report.

New paper out: Nanotyrannus is a different species, not a juvenile T. rex. Growth record of the throat bone in the original skull of Nanotyrannus shows this is a grown-up individual, rather than a growing teenager, that lived alongside the tyrant lizard.

Whether Nanotyrannus lancensis represents a distinct taxon or an immature Tyrannosaurus rex is a decades-long controversy. The N. lancesis holotype is an isolated skull and ceratobranchials, but limb...

Do you need a big brain to fly? Pterosaurs say no. New paper today on brain evolution of lagerpetids and pterosaurs: the first flying vertebrates, pterosaurs, have more similar brains to early Mesozoic gliding birds as Archaeopteryx in volume and shape https://t.co/1ZsFn2K7rl
cell.com
Bronzati et al. show that pterosaurs, the first flying reptiles, evolved brains resembling bird precursors but not modern birds. They also demonstrate that, unlike birds, which built on inherited...

New MADEx paper led by @gravelmonkey_76 in @sedimentology: we refine the geology & paleoenvironment of Mongolia’s Bayanshiree Fm, home to iconic taxa like Segnosaurus & Garudimimus. A 95.5–89.6 Ma age ties it to the peak of the Cretaceous Thermal Maximum🌡 https://t.co/5JrIDqx0wz

🦴💫 Our new paper reveals how the femur records adolescence: during puberty, girls show a clear medullary contraction in bone microstructure, while boys expand the periosteum. A skeletal window into hormonal change! @LaboratorioEH @antrobiolubu1

Medullary contraction during adolescence follows distinct region-specific trajectories along the femur. At the midshaft, contraction appears earlier and more clearly—especially in smaller females—t...
