The only descriptions I can find of these are just that they are fossil shells and have "uncertain affinity", whatever this means. Is it simply not known what organisms they were, animal, plant or otherwise? Are there some speculations?

This is our 6th-8th grade fossil program. I was not going to start running these until the fall of this year but thanks to an awesome donation and a few identifications from @Boesse , I am going to do a few with these with displaced students from Paradise really soon. They need creative education and I need a few opportunities to do the lab and make tweaks. I am super excited and extremely nervous about this lab. Marine mammals are so well adapted to an aquatic life that they really present a great opportunity for presenting complex scientific concepts to kids. The difficulty in using fossils is that I lack the expertise to be able to identify a lot of it but at the same time, I have a number of fossils that are perfect for kids to handle. I do have a basic idea of what fossils I have now so I can start working out a presentation. The first part of the presentation is going to be a quick run down on the basics of classification, using mammals, and the basics of marine mammal biology. We are only discussing two orders of marine mammal, cetacea and carnivora because we only have fossils from those orders. I do have a Desmostylus tusk but I am not going to use that yet. I need a considerable amount more knowledge about that species and its relationship to sirens before I present. We do not have any Odobenidae fossils and I am not sure we ever will. I plan on running down the basic characteristics that separate the two orders. Once we have covered the basics of the two orders, we will discuss the whales in bit more more depth. At each point in the presentation we will present them with fossils that represent the two orders. This is only going to be about 20 minutes. The rest of the time, they will be examining fossils ! Then comes the lab. We will have stations set up that feature some fossils from each order and a visual guide in helping them identify the fossils. Essentially we want them to enjoy checking out the miocene fossils and learning through a hands-on approach. We want them exploring and coming to their own conclusions using the tools they have. The final station will be the students getting a chance to test their abilities by determining if a Cetacean ear bone belongs to an odontoceti or mysticeti type whale. This is the basic outline and I have quite a bit of work to do on this but I really like the potential. I would like to get a few more STH mammal teeth so we have more for the kids to examine and a few more cetacean ear bones as they are diagnostic which is a good thing to have in an education program but overall I feel good about the fossils we have. We have some with identifications but also a few things that are not known which is a good mix. Some of the fossils... Pic 1- a number of different vertebra. There is a shark vert, several cetacean verts and at least one that looks like it might be from carnivora. I have a few more that are not in the picture too. Pic 2- 4 STH Allodesmus teeth, 4 small STH Odontoceti indet teeth ( I will probably suggest Kentriodon to the kids), a STH Aulophyseter tooth, a much different STH Odontoceti indet tooth, and just for fun, a pretty wicked looking sperm whale tooth from North Carolina. This gives the students a chance to visualize the difference between carnivora and cetacea. Pic 3- A few ear bones that will be the final part of the lab. The two STH fossils are the key. One is a mysticeti and the other is an odontoceti. The big one from North Carolina is more for visual flair. It is a big ear bone, the kids will dig it I think. not pictured, the box of bones the kids will handle, the majority of which came via donation.

So I've been reading about paleontology for awhile now, I've read all sorts of books and articles and theses, but the one thing I don't understand is what is the complete list of levels of classification? The average example usually shows eight, in this order: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. But since this is only basic taxonomy there are more than just eight; the ones I know are: Domain, Kingdom, Phylum, Subphylum, Grandclass, Class, Subclass, Infraclass, Legion, Cohort, Grandorder, Order, Suborder, Family, Subfamily, Tribe, Genus, Species, and Subspecies; but then I remembered seeing the clade with dinosaurs and birds was shared, so where is clade in the list, and are there more classifications than I mentioned? If so, then what are they and how many do paleontologists typically actually use, and are classifications used in that order all the time, or are there some classifications that have no specific order?

When trying to classify fossils where the species is unknown which do you use? For example is it Tyrannosaurus sp. or Tyrannosauridae indet.? Edit: Using Albertosaurus as an example, I now believe it is something like this. Since Albertosaurus is hard to differentiate from Daspletosaurus and Gorgosaurus any finds should be labelled 'Tyrannosauridae indet.', but if you could identify it as Albertosaurus and didn't know the species (sarcophagus etc.) it should be labelled 'Albertosaurus sp.' until the species is known.

Are you finding cladistics and taxonomy confusing and complicated? Well, that's because they are, but to help you clear up some of that confusion and find your true place in the classification of life there is a new series of videos out that is still being produced but becoming available very rapidly. Episode 15 of "Systematic Classification of Life" is just out and if you start now watching the first 15 episodes maybe the next one will be available by the time you're done. https://www.youtube.com/watch?v=AXQP_R-yiuw&t=8s

Where to look for Order, and Family for my fossils?
Mediospirifer posted a topic in Questions & Answers
I'm looking to add a specimen to Collections (my blastoid, seen at this link: LINK), and I'm hung up on Order and Family. My field guide gave me the genus and species, and Wikipedia gave me the Class, but I can't seem to find any sites online that routinely show Order and Family--except TFF's Collections, which doesn't (yet!) include any blastoids. Can anyone point me to a resource where I can find this info for a variety of Devonian and Ordovician fossils?- 4 replies

Pattern Recognition Software For Use In Identifying Fossils?
smileylizard posted a topic in General Fossil Discussion
Hi, I'm new to The Fossil Forum. I've noticed surface features on dinosaur bone fossils that exist on species without regard to the scale, mineral makeup, or geophysical location of that item. Striations, bumps, curvatures, texture, etc. I was just wondering if there is a recommended application or graphics viewer which contains an algorithm which could be used to more easily identify and confirm various fossil discoveries? I started looking at DigiKam, but decided to ask here before going down a potentially immersive tangent. even outline of shape would seem beneficial to me at this point...thanks for your time.- 17 replies
