Id help! I’m not sure if this in an animal skull or just a rock
jwestbury posted a topic in Fossil ID
I have this piece from Central Indiana (Generally the Mississippian or Tertiary/Quatemary). What I find fascinating is that it appears to be a nasal cavity. I’m not sure if it’s coincidence or something of actual interest. I took quite a few pictures some with stronger flash so you can see the difference in the different light.

I find skulls one of the most interesting pieces of fossil you can ever own. So here I'd love to see all of your fossil skulls, or parts of one. Here is my Pleistocene era skull of a Ursus arctos. An ice age brown bear. Very very uncommon find.

I have an interesting question when I read a paper (Hurum, Jørn H.; & Sabath, Karol. Giant theropod dinosaurs from Asia and North America: Skulls of Tarbosaurus bataar and Tyrannosaurus rex compared) I only found that it was mentioned in the content, T.rex had stereoscopic vision(Stereopsis), but I did not find any description of the vision of Tarbosaurus. Does anyone know that Tarbosaurus had stereovision? If Yes or No, please explain the reasons and provide a paper to prove it.Please Thanks guys. have a lovely day

Need some help with identifying this skull from Hezheng, China. The seller said it is a young adcrocuta skull, but I think it might be an ictitheriinae. The length of the skull is about 20 cm. Thanks for your help.

Hi all! I love W.R and Oligocene fossils. Both prepping and looking at them. So i thought maybe its time to see what everyone else has collected out there. So let’s see pictures of what you’ve got! Heres a few of mine!

This was recovered near a gold mine in western Montana. I have absolutely no idea what it is. any help would be appreciated. Thanks!

Ok so I was thinking of using resin to coat a skull I have in my collection. Its rather pricey so I wanted to make sure I could protect it from any further damage. The skull appears to be coated with something already since I see a shiny texture in some areas, so should i bother using a resin on it as well ??

Hi there! I'm hoping you can help me narrow down what animal this skull might be. Most likely from the California area. Thanks in advance!

Where to buy the best fossil replicas?
SimpleCollector100 posted a topic in General Fossil Discussion
I am looking to buy replicas for some fossils. I want them to look great but I am unsure of who sales high quality replicas? Are these guys considered good? https://www.dinosaurcorporation.com/hoskre.html I know bone clones is great for animal skulls, etc but is there a similar seller of fossils? Ideally I would want to buy a sabertooth cat skull that was real but I am not sure how to spot the real thing anyway... (unless it was real bone). Thank you -
Hi there! Im a student and really could use some help here! Im doing a phenogram on the similarity of 8 vertebrate, Carnivora skulls, and I dont understand how they work in terms of the number/degree of similarity... on this diagram, the Red Fox seems to have the highest degree of similarity, but to what? All of the skulls? Does this mean the one with the lowest number has the lowest degreee of similarity? Thanks soooo much!

Hi, there. I am seeking for help on an ongoing research. You see, there is two fossil sites in wich I work as a graduate student. We are developing a new method to identify isolated Bison teeth using multivariate statistics. Until now we beign able to differentiate between two ecotypes, a large form and a small form. These are not sexual differences (we alrealy test them and find the sexual difference does not correspond with our findings). The help I need now is if you know someone or directly posess skulls of fossil North American fossil bisons with attached teeth. I only need to identify your skulls and to measure all individual teeth. I currently use 5 variables and all I need is to measure them. Of course, I don't need you to send me the fossils or something like that, I just need you to measure them and send me close up pictures with a scale bar. The species I look for are Bison latifrons (giant bison) and Bison antiquus (ancient bison). I'm already seeking for museum's collections but they have few skulls with teeth on them. If know museums wich have a large number of them I appreciate you give me some info. This are the teeth I need to measure in the upper jaw. I'm also looking for some jaws that are associated with skulls in order to identify the species. This are the teeth I need to measure in the lower jaw. I will be very very thankfull if you can help me people. Thank you very much for reading. HAVE A NICE DAY.

The following data taken from Nowak's classic paper shows the difficulty of relying on size to identify fossils. Summary upper carnassial tooth length of canids: LP4 Canis dirus: 28.7 - 35.5 Canis lupus 22.2 - 30.5 Canis latrans 17.6 - 22.8 Canis familiaris 14.4 - 22.7 Canis armbrusteri 26.6 - 29.5 Canis edwardi 24.0 Canis lepophagus 19.0 - 20.7 In some cases (the fossils) the sample is small. In others, (lupus and latrans) it is more than 100 skulls. Coyotes overlap with wolves, and wolves overlap with Dire Wolves, but in each case, a significant portion of the individuals can be allocated to the correct taxon by size alone. Domestic dogs are a mess, as they overlap with both coyotes and wolves. When you throw in the remaining fossil canids, size ends up being pretty useless as the sole determiner of identity. Usually some knowledge of the geologic context can help eliminate some of the fossil taxa. This is an old data set, and I'll run a similar analysis of Tedford and Wang's data and post that later.
