I found these three pieces on a beach in Mendocino County last week, and I've been trying to figure out what they are. The largest of three measures 46 mm long by 22 mm wide. I'm an entomologist by training, and do not have experience with fossils. I've shared these photos with a couple of friends who are knowledgeable about fish and marine biology, and one suggested that they might be opercular bones from fish, and another thought they might be parts of shells from Acus spp. bivalves. I would appreciate any information or even speculation about what these might be or how I can find out more about them. Thank you for your consideration. --Jamie

I found this about 8 years ago in a dried up creek bed behind my house in the hills of Hayward, California in the San Francisco bay area, USA. We dug it out of some dry but soft sediment and I assumed I found a fungus/mushroom of some sort but now Im not so sure. I am a hobby collector and love it no matter what it is but I would love to have an actual identification. Thanks!

I found this skull on a southern North American, pacific coast beach. From the dense weight of this and appearance of the mouth / teeth area. It appears to have been fossilized??

A new paper regarding a North American metriorhynchid: Eric W. Wilberg (2015). "A new metriorhynchoid (Crocodylomorpha, Thalattosuchia) from the Middle Jurassic of Oregon and the evolutionary timing of marine adaptations in thalattosuchian crocodylomorphs". Journal of Vertebrate Paleontology. Online edition. doi:10.1080/02724634.2014.902846. For trivial sake, Zoneait is named after Zone Ait Ghahnay, a marine monster of Kiowa folklore. Possibly the Kiowa came upon fossils of metriorhynchoids and other marine reptiles (e.g. ichthyosaurs, plesiosaurs) when they came up with mythical beasts like Zone Ait Ghahnay. Oregon's most famous claim to prehistory may lay in the fossils of prehistoric mysticetes, but the discovery of Zoneait and Bennettazhia shows that Oregon was covered by oceans and seas during most of the Mesozoic. I wouldn't be surprised if we found a skeleton of Zoneait in California because the Pacific Coast states were underwater during the Mesozoic.
