How many toes did Giraffatitan have? I tried to research it but all the sites i looked at stated -  "the first toe on its front legs and the first three toes on the hind legs were clawed".

Hi, George. It depends on what you mean by "toes". The front feet had all five digits, but really only as far down as the metacarpals. In humans, those are the bones that run through the palm of your hand, connection the wrist to the fingers proper. But in sauropods, these bones formed a vertical tube that effectively was the forefoot. You can see those of Giraffatitan in this picture: https://svpow.files.wordpress.com/2008/ … jango.jpeg

As you can see, there is one manual phalanx on the end of each metacarpal -- the small bones at the bottom of the forefeet -- but in life these would all have been encased in a tube of flesh. The only distinctive feature of the forefoot of Giraffatitan (as with most sauropods) would have been the single, rather small, claw on the thumb.

The hindfeet are rather different, as you can see in this phooto: https://svpow.files.wordpress.com/2009/10/dscn5292.jpg

They had five more fuinctional digits, somewhat spread out across the ground -- but they too would have been encased in a pad of muscle, gristle and skin, like the feet of elephants. Only the three inner toes would have been visible in life, as they bore claws.

So the answer to your question is either "five fingers and five toes" or "one thumb and three toes", depending on whether you're talking about the skeleton or the life appearance.

By the way, in the background of that second photo, and facing towards us, is a smaller sauropod, Dicraeosaurus. You can see its thumb claws really clearly from this angle.

These specimens are in the main hall of the Museum fur Naturkunde Berlin. If you can get over there some time (and there are good cheap flights available from the UK), I simply can't recommend it highly enough. It's my favourite room in the whole world.
