A specialized bone cell that produces and deposits the matrix that is needed for the development of new bone and consists primarily of collagen fibers. Osteoblasts are formed from osteoclasts on the outer surfaces of bone and in bone cavities, and bone deposition takes place constantly in living bone. As new bone grows and hardens with the addition of calcium and phosphate, osteoblasts become embedded in the bone matrix and develop into osteocytes.
Making the world better, one answer at a time. Many animals live in Rome. The Brown Bear and European Lynx, which were thought to be extinct in Italy, have made a comeback.

The people occupying Italy at the time were a less advanced form of humans called home erectus. These humans were thought to have live fairly close to were Rome was first established. Flint axes were found at a site caled Torrimpietra that is to the west of Rome (kidipede).
