Full reconstructed S aegyptiacus skeleton, Japan, 2009
Spinosaurus may be the largest of all known carnivorous dinosaurs, even larger than Tyrannosaurus and Giganotosaurus. It lived in what is now North Africa, from the lower Albian to lower Cenomanian stages of the Cretaceous period, about 112 to 97 million years ago.
The best known species is S aegyptiacus from Egypt, although a potential second species S maroccanus has been recovered from Morocco.
The loss of this far-from-complete Spinosaurus specimen was especially significant because it was the holotype (the individual used in the first official scientific description of the species).
The RAF's attack on Munich not only wiped out the remarkable Spinosaurus collection, but also the specimen of the carnivorous dinosaur Bahariasaurus, the only known specimen of the unusual prehistoric crocodile Stomatosuchus, and the bones of the long-necked dinosaur Aegyptosaurus.
Additional Spinosaurus specimens would not be unearthed until the 1990s during expeditions to the Sahara.

1945 — , April 24
UK: After five and a half long years, nightly blackouts are finally lifted throughout England with the exception of certain coastal areas.
Britain was blacked out on 1st September 1939, the day Germany invaded Poland and two days before Britain declared war. Everyone had to cover their windows and doors at night (before sunset) with heavy blackout curtains, cardboard or paint to prevent any glimmer of light from escaping and aiding enemy aircraft during the bombing raids. Street lights were switched off or dimmed and shielded to deflect the light downward. Traffic lights and vehicle headlights were fitted with slotted covers to deflect the beam down to the floor.
British wartime poster
Thousands of Britons died in road accidents during the Blackout, increased by the lack of street lighting and dimmed traffic lights. To help prevent accidents, white stripes were painted on the roads and on lamp-posts. People were encouraged to walk facing the traffic and men were advised to leave their shirt-tails hanging out so that they could be seen by cars with dimmed headlights. Others were injured tripping, falling down steps or bumping into things because they could not see in the darkness.
