Now on display in Paris in the Gallery of Paleontology and Comparative Anatomy (sadly, in a stairwell), it’s an excellent fossilized skeleton of a Palaeotherium Magnum:
Palaeotherium is an extinct genus of quadrupeds, most closely related to modern-day tapirs and horses. Based on the large number of their fossils that have been found to date, they widely roamed the forests that covered western Europe some 45 million years ago. But Palaeotherium browsed on low-hanging leaves (up to about 1-1/2 meters above the ground), leaving it at a disadvantage when Europe dried out, and the ancient forests were replaced by grasslands.
Most species of Palaeotherium were small, measuring about 75 cm (2-1/2 feet) tall at the shoulder. Palaeotherium Magnum was the largest of its kin, nearly reaching the size of a modern-day horse.

Morsels for the Mind – 15/05/2015
This week’s sciencey image comes to you from the “Mythic Creatures” traveling exhibit — it’s a 500 year-old carving of Ahuizotl:
Courtesy of the Smithsonian Air & Space Museum’s Udvar-Hazy Center, here are two small bits of history you’ve likely never seen before — arming plugs for the “Little Boy” atomic bomb:
From the placard:
Small metal plugs were used by the Enola Gay weapons officer to arm the atomic bomb dropped over Hiroshima on August 6, 1945. He removed three green plugs that kept the firing circuitry inactive and replaced them with red plugs that closed the circuits. These plugs were found in the navigator’s compartment of the Enola Gay during restoration. It is not known whether the green “safe” plug is from the “Little Boy” atomic bomb or was used on a practice mission. The red plug was probably a spare.
Courtesy of the Smithsonian National Air and Space Museum’s Udvar-Hazy Center, it’s (a very good replica of) the Pioneer 5 spacecraft:
Pioneer 5 (a.k.a. Pioneer P-2, and Thor Able 4) was launched on March 11, 1960 on a Thor-Able rocket, to explore the space between the orbits of Earth and Venus. It wasn’t a particularly large spacecraft by modern standards, weighing only 43 kg (94 lb) — but it provided the first maps of the interplanetary magnetic field (which had only been suspected to exist), and gave scientists new measurements of cosmic radiation.
It may be that when you look at this vessel, you’re thinking two things:
1) The decoration on it looks Mayan
2) You can’t read any of it
If so, you’re right on both counts — it’s a Mayan vessel, but the decoration on it only looks like Mayan hieroglyphs. Basically, it’s Mayan-themed gibberish.
Courtesy of the National Air and Space Museum in Washington, D.C., I present to you the Lockheed XP-80 Lulu-Belle:
If your memory is good, this bird may look a bit familiar to you. Lulu-Belle was the prototype for the P-80 Shooting Star, the first operational U.S. turbojet fighter to see full production. Designed and built in an amazing 143 days, the airplane first flew on January 8, 1944. It became the first U.S. aircraft to exceed 800 kilometers (500 miles) per hour in level flight, and its P-80 and F-80 descendants barely missed active service in World War II. Continue reading
I talked a bit about the Me 163 some time back — but a recent trip to Washington D.C. left me with a bit of time for the Smithsonian National Air and Space Museum’s Udvar-Hazy Center, which meant I was able to get some shots of their copy of the “Komet:”
This is a B1 model of the craft — so, in the middle of its development history, and the only variant to see operational (if ineffective) use.
