Large (almost 1 1/4”) Ganges River Shark tooth from North Central Java. Late Pliocene- Early Pleistocene. Photos don’t do this tooth’s coloration justice. -

Hello. Found this teeth in Sangiran, Java, Indonesia. Looks like omnivore teeth. Maybe wild boar. Any idea? The length measurement in the pic was in cm.

I bought this fused vertebrae Saturday. It was listed as being from a Megoceras from Java Indonesia. I can not find any mention online if a Megoceras. So I am wondering if the fossil was labeled wrong and it's from something with a similar name like megaloceros. Any ideas? Thank you

From the album: TEETH & JAWS
Stegodontidae is another family of Proboscideans, however there is debate on whether it is a valid family or if it belongs to Elephantidae (Shoshani and Tassy, 1996; Saegusa et al., 2005). The group is comprised of two genera Stegolophodon and Stegodon which are thought to have evolved from gomphotheres. They were among the largest proboscideans to roam the planet. They [stegodontids] had low crowned teeth (brachyodont) with peaked ridges indicating they were browsers or mixed feeders in a forested environment. This is in contrast to the high crowned plated molars of mammoths and elephants. In general Stegodon had long, nearly straight tusks while Stegolophodon had four tusks, two on top and two on the bottom. Their bones were generally more robust than mammoths and elephants. The earliest Stegolophodon fossil is from the early to middle Miocene in Thailand. The genus spread from its southeast origins along the coastline of East Asia. It is thought that this northward movement of the genus is a result of the mid-Miocene climatic warming (Saegusa, 1996). The genus Stegodon evolved from Stegolophodon. It most likely originated during the Pliocene in South China based on the high diversity of this genus in the area, however there is a reported record of the genus from Kenya, Africa dated at 6.5 million years ago. From South China, Stegodon rapidly diversified and spread through Asia (Saegusa, 1996). They were able to swim and reached many islands in southeastern Asia (even islands that were not connected during low sea levels of glaciation periods). Stegodon diversified on the Japan islands resulting in several endemic species (Saegusa et al., 2005). Elephants reached Asia during the Pliocene and by this time stegodontids were very diverse suggesting that elephants and stegodontids may have co-existed. The loss of stegodontids in Africa may have been the result of increasing grassland on the continent.

Well, I sure feel like a nitwit! Remember this topic I made, about how it's wise not to throw away your supposedly-fake fossil, because even the experts can get it wrong? > http://www.thefossilforum.com/index.php?/topic/57593-this-is-why-you-shouldnt-discard-your-fossils-even-if-they-are-supposedly-fake/ Guess what? You guys were right all along - It IS a fake, or at least, the root is. So for 2 years I've been trying to ID the tooth. It looks like the crown of a croc, yet has a full root. I asked the seller, but he was adamant it was a real tooth. I checked with several other experts, and a taxidermist. After handling it, all confirmed my tooth and root was real. Hence, despite Thomas Kapitany, Nate Curtis and you guys telling me otherwise, I was convinced mine was real. Still, I just couldn't lock it down to a species. Was it tiger? Croc? Pinniped? Whale? Then a group of big cat fans messaged me, asking for info on my tooth, e.g. weight, length... They did a lot of calculations, cross-section fitting of my tooth into tiger jaws etc, and came to the conclusion mine was the fabled lost canine of the Ngandong Tiger. As a collector, I was more than happy to accept that ID. For months, I was happily ignorant. But I couldn't ignore my nagging suspicions this tooth isn't what it appears to be. I went online to search, and what do you know? I found 6 other Java teeth like mine, all ID-ed as tiger. I have 2 teeth, and my friend has 3, that means all 11 of these teeth that are known online are fully-rooted. Let that sink in a moment. Fully-rooted teeth are rare in the fossil record, and now 11 out of 11 have that? Not likely at all. I tried looking for instances with partial roots, or broken ones but there were none. Here's an album compilation of the 11 teeth > http://imgur.com/a/hhWcC As it turns out, the Javanese really like tiger. I found 4 Indonesian seller marketing croc teeth as tiger ones. Thomas Kapitany also revealed to me they've been faking fossils for decades. I broke my smaller tooth apart, this is what I saw > http://imgur.com/a/4F8iJ Let me say first the Javanese are darn good at faking this. I thought I knew plenty about Moroccan and Chinese fake fossils, but this one just threw me off utterly. I will relabel my smaller tooth crown as a croc, and the big one will stay as it is - a reminder to myself to be neutral when it comes to ID-ing a fossil; I was so biased towards tiger that I failed to see all the red flags. Too often, the problem many of us is that a collector refuses to acknowledge when he has a misidentified fossils (e.g. a concretion instead of an egg, rugosa coral instead of teeth). I happened to be one of them. Sometimes, the experts really do know better

Some Indonesian friends have given me some odd rocks that look like some insect or fish or other odd animal which I cannot define. Joining some pictures. Please, help me identify those strange fossils...
