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.
I found this recently in an Early Mississippian lag deposit amongst several other fossils, including shark's teeth, bones of unidentified critters, and phosphatized inverts. From my observations, I believe that the site represents an estuarine setting. I don't find any plant material here, but that doesn't mean that terrestrial critters might not show up. I have my own opinions about the piece, but let me know what you think! Early Mississippian Cumberland Plateau Size: approximately 1cm across
Hi. I'm new to the Forum, but would like some opinions about this object I found here in Alaska. It was found in a tidal creek in an estuary in southcentral Alaska. The estuary surface is a mix of gravel, mud, and glacial silt. I've shown this to various local experts, and most think it is some kind of broken fossil, but a few think it isn't a fossil at all. Any thoughts would be appreciated.
I have about 8 acres of coastal estuary in northern Nova Scotia, and decided to take a look at the estuary sediments to see if I could find any fossils. Yes, they are there! Microfossils and lots of other life including ostracoda. Using my hand lens I could see them very well. Will invest at sometime in a microscope and maybe I will see even more. Hand lens for scale for foraminifera and ostracod scale is in millimeters.
