The remains of 84 bird specimens of 18 different species, including motmots, doves, trogons, cuckoos, wrens and orioles, were discovered at one spectral bat roost.
Thousands of specimens, hundreds of tons of bones, have been recovered from the bottom of the North Sea, termed doggerland, and continue to be recovered.
Two specimens have red-brown radiating streaks on an emerald-green ground colour on 3rd and 4th whorls, streaks extending on to peripheral lira (cf. capensis).
Specimens are stored in low gas-permeability plastic bags with desiccant added to reduce humidity, and may be kept at ambient temperature, even in tropical climates.
It was horrible, a writer said, the 400 miserable, helpless, emaciated specimens of humanity, subjected for months to the malarial atmosphere of the river bottom.
