Placites sp. from Mt. Feuerkogel, preserved with sickle-ribs. On original matrix. This specimen's geologic age is Norian Lac-Alaun. The Norian is an age within the Late Triassic and is broken down into three substages, the Lacian (Lac) Alaunian (Alaun) and the Sevatian (Sevat). This particular specimen comes from one of the first two substages.

This reminds me a little of some of the Madagascan Cleoniceras ammonites, but the sutures are... unusual. Somewhat rounded at the ends. It's 86x69MM approx. I'd appreciate any input.

Hello! Did some fossil shopping locally; picked up this nice piece. All I know from the store is, Ammonite - TImor - Indonesia. Is it a Ceratite ammonite? I thought perhaps with that pattern, it could be. Any idea on age? Triassic? Many thanks in advance!

Dear members of The Fossil Forum, I am busy on the identification of all the fossils in my collection, but some fossils are causing trouble, one of which I will show here. It is 23mm. The name tag says it is an Arctohungarites sp. but in my opinion the umbilicus is too big for Arctohungarites. It looks more like Nordophiceras but I do not know if the fastigate venter is common for that genus. It might very well be neither of these genuses, my knowledge on Siberian ceratites is very limited. The findspot is Northern Siberia, but where exactly is not stated. I know of two sites, Cape Tsvetsov and the Olenek river, does the preservation of this ammonite point at one of these two? The age of the ceratite is said to be Middle Triassic, which means Anisian-Ladinian, although most of the siberian triassic ammonites are Olenekian in age. Apparently Arctohungarites is an Anisian genus, but I am not sure that this ammonite is an Arctohungarites. So my questions are: What Genus and species is this ceratite? Where does it come from? What age is it? Is there anyone who can shed light onto this ceratite and help me? Thanks in advance, Sander
