Today I heard Paul Scofield, Senior Curator of Natural History at Canterbury Museum, give a public talk on moa resurrection and the museumʻs partnership with Colossal Biosciences (the “dire wolf” people).

Fossil Whales of the Pacific Northwest and the Evolution of Baleen
Fossil Whales of the Pacific Northwest and the Evolution of Baleen YouTube video by Southwestern Oregon Community College (SWOCC)

#worldwhaleday Last week I was invited by @paleowin.bsky.social to give a lecture at her institution (SWOCC) on the evolution of whales. If you want to learn about about the origin of baleen and the importance of fossils from the Pacific Northwest, watch here: 🐬🦖🧪 www.youtube.com/watch?v=s7jg...

This is Messapicetus gregarius from the Pisco Formation, a comically unserious animal.

This is a longirostrine basal Ziphiid (beaked whale) that, alongside the more typical enlarged teeth in the lower jaw tip, preserves a functional toothrow in both jaws!

(The crocodile is Piscogavialis!)

Today, the historic #HighSeasTreaty enters into force.

The majority of the high seas is deep sea.

As the COP process begins, the deep and the threats it faces must be at the center of implementation.

Vector illustration of Piscogavialis laberintoensis, a marine gharial from Miocene Peru, swooping through the water towards the viewer. The long snouted crocodilian has large, forward facing eyes and narrow, needle like teeth. It is dark grey with a stark white and coppery underbelly, and dark stripes down its back and tail.

A picture of green jay feathers (Cyanocorax luxuosus). They are all lined up and organized: primaries, secondaries, coverts, tail feathers. Most of the feathers are gray with a green tip.

I just stumbled upon featherbase, a database of feather pictures from a bunch of bird species.🪶

So pretty!

The snows have been surprisingly plentiful here. Hopefully some of it makes its way across the channel!

Like identifying trends in prehistoric animal rosters in games isn't... this feels like a distraction

The 野史 (or maybe actual history?) is that the British released them from the Government House, where they were being kept, right before the Japanese invaded to give them a chance

Photo montage of Tinamus resonans sp. nov., a new species of tinamou from the montane forests of the Serra do Divisor, western Amazonia, Brazil. The species is distinguished by a unique combination of plumage pattern, vocal repertoire, and ecological characteristics, including a conspicuous dark slate facial mask, vivid rufous-cinnamon underparts, and a uniform brownish-gray back. Its vocalizations are remarkable, consisting of long and powerful songs that echo strikingly across the steep montane slopes, producing a characteristic resonant effect. The species was documented exclusively at higher elevations within a transitional zone between submontane and stunted forests, where the understory is densely structured by root mats. A preliminary population estimate, based on field detections and spatial extrapolation, suggests approximately 2,106 individuals restricted to the Serra do Divisor massif. Although no immediate anthropogenic pressures were observed within its range, the species may be highly vulnerable to climate change and to proposed infrastructure projects that threaten the integrity of this federally protected region. The discovery of T. resonans highlights the biological uniqueness of the Serra do Divisor, reinforces its status as a center of montane endemism, and underscores the critical importance of maintaining its long-term conservation.

The Gigantopithecus segment is easily my favourite of the season, and potentially even of the series as a whole. Incredibly convincing GCI, interesting behaviour and a good story on top of it all.
