Another medical doctor, the practising gynaecologist Jean-Pierre Duhard, is equally certain that he knows what’s what. In the course of his work, Duhard has seen many naked women, and he says that modern women exhibit the same range of shapes and sizes as the Venuses. He backs up his contention with a plate of line drawings of modern women, below (554). Like Colman, he recognizes some medical conditions. However, Duhard’s conclusion is that Palaeo artists were simply working from life and producing portraits.
I watched some gulls dancing over waves today, plucking out morsels after each breaker. I managed to snap some photos because I thought they would make good reference. I didn’t plan on using the photos so soon, but there you go. Sometimes inspiration strikes.
I haven’t painted anything in a while. The gulls became Pterosaurs. This probably isn’t strictly accurate, but I
wanted to catch the feel of the creatures as real animals rather than lizardy death machines.
Sweden is the first western nation to change its nutritional guidelines to low carb high fat!
Yep, the Swedish Council on Health Technology Assessment recently released a report “Dietary Treatment for Obesity” after a two-year study on different eating patterns. As a result, they have changed their national nutrition guidelines to a low carb high fat diet. Progress!
@a-dinosaur-a-day, for the person asking about potential sexual dimorphism in Sinosauropteryx:
I asked Jakob Vinther and he says it would be pretty dificult to tell wether there was dimorphism in colouration for Sinosauropteryx, mostly due to the fact that there are so few confirmed specimens- only around three. And to be sure that it was the sex of the animal responsible for the colouration one would have to rule out other factors for different colouration such as age, habitat and potentially status in a group. Another difficulty with Sino. is that the specimens are millions of years apart so any colouration differences could also just be residual of a shift in pattern over time.
However, he is currently working on a much more detailed follow-up study of the colouration of Sinosauropteryx, the preliminary results of which suggest it had a “face mask” pattern in darker colours on its head.
A much better candidate for investigating sexual dimorphism in colouration is Anchiornis, for which we have hundreds of specimens preserved in minute detail. Already, studies have revealed some differences in colouration between individuals, notably that the white tips of some feathers are distinct sizes on different individuals as seen today in some chickens where males have small spots of white at the ends of their feathers and females have large spots.
The research you’re looking for is almost certainly going to be published in the next couple of years. Jakob hopes to do it himself but as the specimens are Chinese and the Chinese government is rightly very protective of their amazing fossils it is difficult to get a hold of them. But if Jakob doesn’t publish, someone else will.
According to this article from Past Horizons, this art was discovered by Canadian archaeologists in the 60s and was simply “forgotten” until it was rediscovered in 2005.
The deposits covering the rock art, in part composed of wind-blown sediments, were dated at the Laboratory of Mineralogy and Petrology (Luminescence Research Group) of Ghent University (Belgium) using optically stimulated luminescence (OSL) dating. OSL dating can determine the time that has elapsed since the buried sediment grains were last exposed to sunlight. Using the constituent mineral grains of the sediment itself, it offers a direct means for establishing the time of sediment deposition and accumulation. This resulted in a minimum age of about 15 000 calendar years, providing the first solid evidence for the Pleistocene age of the rock art at Qurta and making it the oldest graphic activity ever recorded in Egypt and the whole of North Africa. The Qurta rock art is therefore more or less contemporaneous with European art from the last Ice Age, as known from such world-famous sites as the Lascaux and Altamira caves.
