This is a piece of late Miocene palm “wood” from Orinda, California. Not a true wood; it is part of the Palmoxylon form genus. Palm wood can rarely be attributed to a palm species identified by foliage or fruit such as Sabal. It was found in a landslide area on top of sedimentary interbeds of the Moraga Formation and the younger lacustrine Siesta Formation sediments. Volcanic rocks and possible spring deposits are nearby. Fossilized palm roots, reeds and petrified wood occur in the area. This piece and others found in the area represent the youngest palm fossils found in
I found this bone in lake limestone near the late Miocene Moraga Formation east of San Francisco. Animals fossils in the area include, horses, hippos, antelopes, mastodons. Any idea what part of the anatomy this is: knee, vert? What animal? Dimensions 8cm x 8cm x 5cm high. Pictures of other bones have been IDed as possible camel leg bones. Four photos taken while the top is being rotated toward me. First photo is front. Second is top. Third is back and fourth is bottom. Thanks, John
