RockSand Posted September 27, 2018 Share Posted September 27, 2018 Found what may be a vertebra, sticking partially out of the ground on private property near Phoenix, Arizona in Maricopa County. The soil is hard-packed coarse sand/silt/gravel with areas of clay. A landscaper added a top dressing of decomposed granite and river rocks - a typical desert landscape design around here. The specimen likely was transported to the site in the river rock. Luck me! Other fossils found in the landscape material lead me to believe it came from a healthy and diverse marine environment with turtles, fish, shark, crocodilia, lizards, skate, snakes and mammals. The entire area was once an inland sea. The specimen is approximately 6.5 cm length x 5 cm width x 2 cm height. (Lateral measurement varies from 1.5 cm to 2.5 cm.) The vertebral body is 5 cm length x 4 cm height. Let me know what you think. The "tooth" on the distal side measures 2 cm. Link to comment Share on other sites More sharing options...
ynot Posted September 27, 2018 Share Posted September 27, 2018 Welcome to TFF! Sorry but this is not a vertebrate or any type of fossil. It is a concretion. 1 Darwin said: " Man sprang from monkeys."
