When you're excavating all these little crown conchs like the one on the top that people ate and discarded about a thousand years ago, and then can walk 20 meters to the shore and pick up a live one. From southwestern Florida a few years ago! #archaeology #ecology

An archaeologist excavating in a trench. He’s kneeled down and the trench is higher than him. The bottom of the trench is covered in water as it is deeper than the height of the water table.

As a person whose work often ties them to the scope for many hours at a time, I’m forever amazed by the microworlds that we can easily miss within and among ordinary archaeological remains. There is almost always much more to see and learn if we just look a little closer. πŸ”¬πŸͺπŸŽ£

A high resolution microscope photo of a fish scale. It has nested circular ridges like a finger print. But in its texture looks like a finger nail!

200 year old fish scale from a plantation-era trash pit. We’re finding hundreds of fish scales (in both historic and earlier Indigenous contexts). Matthew and Christina are going to explore micro approaches to species identification! #archaeology #ecology #fish #fisheries #history

Stay tuned for our forthcoming paper demonstrating a key link between more autocratic forms of governance and a reliance on external financing.

Also see Blanton et al. 2021 on the topic of financing (www.journals.uchicago.edu/doi/abs/10.1...): (see passage below)

…good gov policies will be instituted when revenues that underpin gov are jointly produced, as predicted by collective act theory…good gov will be weakly expressed when private wealth plays an uninhibited role in political agency and when leaders have direct, discretionary control over fiscal econ.

Illustration of a common porcupine from the early 19th century, depicted in black and white engraving style. The porcupine is shown in profile, clinging to a vertical surface with detailed quills fanned out behind it. The quills have distinctive dark and light banding patterns. Its rounded head, small eye, and clawed feet gripping the surface are clearly rendered. The image is labeled "COMMON PORCUPINE" and includes the page number 122, reflecting its origin from a historical zoological text published in London between 1800 and 1826.

About to date some of the earliest pottery in North America! These were tempered with Spanish moss c. 4800 yrs ago. Charred fibers are preserved in the sherd and can be directly dated! Note the swirly linear voids left from fibers that were burnt out in the production process #archaeology #history

Illustration of a prickly pufferfish (Diodon orbicularis) with a round, inflated body covered in sharp white spines. The fish's body is brown on top and fades to yellow with dark spots on the underside. It has bright red fins – two pectoral fins, a tail fin, and a fin near the rear. The head features a small eye and an open mouth. The background is plain beige with handwritten text on the upper right, naming the fish in several languages including English as "The prickly Bottefish." This detailed 1796 natural history drawing highlights the fish's distinctive spines and coloration.

BREAKING: The Department of Education has ended its directive that attempted to restrict diversity, equity, and inclusion efforts in schools nationwide.

This is a victory for academic freedom and education equity.

Photo of an Ancient Egyptian artists’s small, naturalistic painting of a standing hippopotamus on a flake of white limestone, dated  c. 1479–1425. The hippo is painted in profile with head lowered and to the right. The body is outlined with black paint and painted brown. The belly, eyes, and ears are painted red. Although the ancient Egyptians were well aware of the danger and destructive power of hippos, this painted hippo has rather a friendly face! Dimensions: H. 10.8 cm (4 1/4 in); W. 12 cm (4 3/4 in); Th. 1.7 cm (11/16 in)

Egyptian artists made practice sketches on flakes of limestone, sometimes for use as templates when transferring an image to the wall of a tomb or a temple. Limestone flakes were readily available because of the constant construction of temples and rock-cut tombs. A number of such sketches were recovered at Deir el-Bahri during the 1922-23 MMA excavations. This painting was acquired by the museum in the division of finds.
