Lunate bone Lunate bone The lunate bone (semilunar bone) is a carpal bone in the human hand. It is distinguished by its deep concavity and crescentic outline. It is situated in the center of the proximal row carpal bones, which lie between the ulna and radius and the hand. The lunate carpal bone is situated between the lateral scaphoid bone and medial triquetral bone. The lunate is a crescent-shaped carpal bone found within the hand. The lunate is found within the proximal row of carpal bones. Proximally, it abuts the radius. Laterally, it articulates with the scaphoid, medially with the triquetral, and
Dreadnoughtus parts of the skeleton suggest that the only known individual of "Dreadnoughtus schrani" was approximately long and stood about 2 stories tall. At 1.74 m, its scapula is longer than any other known titanosaur shoulder blade. Its ilium, the top bone of the pelvis, is also larger than any other, measuring 1.31 m in length. The forearm is longer than any previously known from a titanosaur, and it is only shorter than the long forearms of brachiosaurids, which had a more inclined body posture. Only "Paralititan" preserves a longer humerus (upper arm bone). Although each species likely had slightly different
