Nebfossil Posted January 27, 2021 Share Posted January 27, 2021 Anyone know if this is the head of a trilobite? I know some big ones are found there. Also what is the third pic. Been there many times and never found these two. Link to comment Share on other sites More sharing options...

ScottBlooded Posted January 27, 2021 Share Posted January 27, 2021 Very cool find, I’ve been hoping to happen across one of these at one of my usual dig sites (also Hamilton), but no luck yet. Link to comment Share on other sites More sharing options...
Jeffrey P Posted January 27, 2021 Share Posted January 27, 2021 I agree with the diagnosis: Dipleura dekayi. I've seen individuals that were collected at Seven Stars. They are prevalent in a number of Hamilton formations, especially in Central New York and Central PA. The trick is finding a complete one. Those are fairly rare. I do admire partial specimens like yours. Nice job! Link to comment Share on other sites More sharing options...
Top Trilo Posted January 27, 2021 Share Posted January 27, 2021 Whoever named this likes coelacanths, or who ever named a coelacanth likes this trilobite. the name diplurus newarki looks a lot like dipleura dekayi. Luckily I have Tim's avatar to help me remember which is which. “If fossils are not "boggling" your mind then you are simply not doing it right” -Ken (digit) "No fossil is garbage, it´s just not completely preserved” -Franz (FranzBernhard) "With hammer in hand, the open horizon of time, and dear friends by my side, what can we not accomplish together?" -Kane (Kane) "We are in a way conquering time, reuniting members of a long lost family" -Quincy (Opabinia Blues) "I loved reading the trip reports, I loved the sharing, I loved the educational aspect, I loved the humor.

piranha Posted January 28, 2021 Share Posted January 28, 2021 3 hours ago, Top Trilo said: ...the name diplurus newarki looks a lot like dipleura dekayi... Here is the Greek etymology: [diploos = twofold] [pleura = ribs] [ouros = tail] Dipleura Green 1832 This genus derives its name from two Greek words, which signify double ribs; many of the trilobites are thus characterized; but in no species, is this organization so remarkable as in those which belong to the genus Dipleura. Green, J.M. 1832 Monograph of the Trilobites of North America: With Coloured Models of the Species. Philadelphia: Joseph Brano Publishing, 93 pp. Diplurus Newberry 1878 In Holophagus and Undina and in the Jurassic species of Coelacanthus described by T.C. Winkler, the supplemental caudal fin seems to spring directly from the extremity of the caudal. In Diplurus there is a distinct interval between them; a character which suggested the name Diplurus, or double-tail.
