An extraordinary Acheulean handaxe knapped around a fossil shell circa 500,000-300,000 years ago.
The maker appears to have deliberately flaked around the shell to preserve and place it in a central position. As a result this handaxe has been described as an early example of artistic thought.
From West Tofts, Norfolk.

Ardenna buchananbrowni Tennyson et al., 2024 (new species)
(Type specimen of Ardenna buchananbrowni, from Tennyson et al., 2024)
Meaning of name: buchananbrowni = for John Buchanan-Brown [discoverer of one of the two known specimens]
Age: Pliocene (Piacenzian), 3.06–3.36 million years ago
Where found: Tangahoe Formation, Taranaki, New Zealand
How much is known: Partial skeletons of two individuals, together representing most of the skull, much of the forelimb skeleton, and several vertebrae.
Notes: Ardenna is a genus of extant petrels. These seabirds feed on fishes, crustaceans, and cephalopods using a variety of foraging styles, including grabbing prey while swimming on the water's surface and diving underwater to pursue them. Within the genus Ardenna, the short-tailed (A. tenuirostris) and sooty shearwaters (A. grisea) have particular anatomical specializations for diving, such as flattened humeri (upper arm bones).
A. buchananbrowni also exhibits these adaptations in its skeleton, making it the oldest known diving-specialized member of this genus. It was smaller than most extant Ardenna species, and lived alongside a larger extinct species that lacked diving specializations, A. davealleni.
Reference: Tennyson, A.J.D., R.B. Salvador, B.M. Tomotani, and F.G. Marx. 2024. A new diving Pliocene Ardenna shearwater (Aves: Procellariidae) from New Zealand. Taxonomy 4: 237–249. doi: 10.3390/taxonomy4020012

Artwork from 2015, edited in 2024.
Path of life, from birth to death… of growing up, shining, and decaying. The power of life, the agony of being alive.
I think it's still my favorite hyena artwork ~
