Quote from Denton, 2013, p. 790: "Lampanyctus petrolifer and Lampanyctus bolini (David, 1943), are likely not assigned correctly (Fitch, 1969; Prokofiev, 2002). Fitch (1969:14) notes a communication from R. Lavenberg that L. petrolifer is instead a Lepidophanes, and that L. bolini is instead a Diaphus. Although neither rediagnosis was accompanied with character data, examination of several L. petrolifer specimens at the LACM supports assignment of L. petrolifer to the Lampanyctini subclade containing Bolinichthys, Ceratoscopelus, and Lepidophanes, based on the unique morphology in this subclade of the procurrent caudal rays, and on the large size of the orbits in the cranial profile.” References: David, L. R. (1943). Miocene Fishes of Southern California. Geological Society of America Special Paper 43:1-187. Denton, John S. S. (2013) Lanternfish (Teleostei, Myctophiformes, Myctophidae) body fossils from the Modelo Formation (upper Miocene) of Los Angeles County, California, Journal of Vertebrate Paleontology, 33:4, 786-793, DOI: 10.1080/02724634.2013.751919

So, I have two more fossils (I think), that I could really use help with.... Both found in same location(s) and formation(s) as my prior posts. The first, looks like the impression of a mollusk/shell to me (about 3/4' in diameter) ??? The second, I cant even begin to guess as I would probably be wrong anyway. lol Its corkscrew in shape and about 3/4' long. It left a mirrored impression of itself on the opposing rock. Any thoughts???!!! Thanks in advance. :0)
