While fossils of baby enantiornithines, a group of abundant and diverse early-branching birds, are already well-known, our Alaskan fossils are the first Mesozoic remains of baby euornithines, the clade that includes modern birds and their closest Cretaceous relatives!

What are those tiny fossils?
They're birds. That just hatched. That lived in the Arctic. 73 million years ago.
And thus: polar bird nesting colonies are not new, but a long-term norm of Earth history.

Birds were nesting in the Arctic during age of dinosaurs, scientists discover
Minuscule fossils from 73m years ago are oldest evidence yet for birds nesting in polar regions

Hi guys. On world bee day today, don't forget that honey bees are actually doing ok! It's solitary and subsocial native bees like mason bees and bumblebees that need our help.
I'll post some resources in this thread on how you could help them, even if you don't have a yard to plant native flowers!

Happy Birthday, Mary Anning!
This 195-million-year-old marine reptile was discovered in Lyme Regis at some time before 1836 by the British palaeontologist Mary Anning (1799–1847).

Happy to have had the opportunity to write a short article discussing the findings of an exciting recent paper on the diversification of burrowing behaviour in mammals by Pinkert et al. authors.elsevier.com/a/1kzR93QW8S... (Full access via link until 10.06.25)
