Is it safe to select geology from optionals having no science or engineering background?" Need Suggestions from seniors who've selected this subject in the past and aspirants, currently, who've selected this subject with no science background. Is it manageable to prepare? (please, share your experience and marks with preparation strategy, if possible) it would be really helpful. Thanks in advance!

Silver Ore Platinum :-) No but seriously though I dont know which it is...
Visero posted a topic in Rocks & Minerals
I found this while digging at a placer in south west Montana. It does react just a little bit to a neodymium magnet. It is slightly larger than a grape fruit and around 3.5lbs so a bit heavy for its size.

Any Thoughts?

I'm just gonna start dumping pictures here of cool stuff I've found. All of this stuff is from the outdoors; I mean sure, I have some cool store-bought stuff like snowflake obsidian but that's not what I'm interested in sharing here. Some of this stuff I have in the other thread I started, but I'll post other stuff too. Nice lil' Hag Stone "The Brain" uhm....."Concretions" (Still working on an ID on these) Really old Coal (I think the term is anthracite?) Glassy rock I found, not sure what it is exactly. Garnet-y bits.

These are not mine, but found them while doing security rounds for a brine extraction company in Northern Michigan. They are halite crystals from drill cores for wells that extend out under Lake Michigan, from a depth of about 2000 feet. I'd love to have them, but can't find the proper manager to ask. Some are over 1 inch on a side.

Hello guys! I'm Bradai Mohammed from Algeria, I'm a geologist, graphic designer, Mag. Editor, addict of fields, and fossil hunting, I confess. Currently preparing my Master degree in Geology of Sedimentary Basins (actually nearly done) working on the Foum Tineslem Fm. (Tremadocian) of the Ougarta ranges. Like the majority of geologists, I have a humble collection of minerals, fossils and even shells from different ages; and recently entering the world of fossils prep. To see my collection, visit my account on Instagram @the.gneiss.mo The reason I joined this forum was to look for specialists in Brachiopods, Gastropods, Ammonites, etc., in order to properly ID my fossils, and I hope we get to know each other and make friendships. I'm honored to share with you the same passion and love.

Hello all! I feel like I should've discovered this forum earlier due to my interest in the subject, but luckily watching PaleoChris on YT introduced me. My name is Michelle and I'm 22 years old. I just graduated from college (last Friday actually) with a Bachelor's Degree of Science in environmental science, concentrating in soil science and hydrology and minoring in geology. I've always had a passion for geology, and have been collecting and attending shows since I was around 8. My collection is at about 300 specimens right now, with a really clear Indicolite piece at the top of my favorites. My love for geology is so obvious that some of my professors and classmates tried many times to switch my major to it! While I do love mineralogy and that is my strong suit, I've recently found myself immersed in paleontology (and hey, you can never have enough interests). I've been rockhounding and fossilhounding around the Northeast for the past couple of years, and my favorite trips include the Adirondacks (Ticonderoga), Ogdensburg, and Port Clinton. I recently took my first trip to Big Brook in May but only found a couple of Belemnites and Sawfish teeth due to the season. I can't wait to go next spring though! I also love photography of all types and have recently decided to pursue a Graduate Gemologist Degree from GIA once my student loans are paid off. I'm really excited to join this forum because there are not nearly enough people I know that have the same passions that I do! Also, I don't do nearly enough collecting and sightseeing because I don't really know good spots. So tell me your favorites! If you've never been, I recommend seeing the Stromatolites and Oolites in Hamburg, Sussex County.

Look guys I have a... well its definitely a something? Is it a plant, the top of a crinoid, a broken tooth, a really tiny volcano??? No idea. And as a bonus I have no idea where it came from either. It was given to me ages when I was a kid. So if you've got any ideas on what the heck it might be, I'd love to hear 'em! Thanks!

Hey everyone. I thought I'd share some of the things I found on my last fossil hunt. So.. Many.. Fossils! One might even say that there were a plethora of fossils. If I could, I would've taken them all with me, but sadly my backpack can only carry so many rocks. I was literally examining each rock I had, trying to decide which to carry back and which to leave behind and how many I could fit in my pants pockets before they started to fall down. Eventually I decided to just stop looking for fossils and hike back to the jeep. This lasted all of 3 seconds before I found another a beautiful byrozoan and was trying to figure out how to fit it in my pack. The byrozoan and the sponge below are my favorites since i don't see many of them and the brachipod in the matrix just looks cool. lol Its fascinating to look at these fossils and think about how Arizona used to be completely underwater long, long ago.

Hey guys, I'm back with another ID question. The fossil I'm trying to identify is in the 1st picture. I think that what I have is a fossilized brachiopod WITHOUT the shell. What do you guys think? It's the same general shape, but the color and textures of this fossil look different than others I've found in the area. The symmetrical textured part in between the two humps, I've never seen before. Pictures 1,2, and 5 show the fossil in question and pictures 3 and 4 show examples of other brachiopods that I've found. The last picture is an example of a brachiopod that was broken in half, exposing the animal inside. (when I uploaded the post the pictures got out of order) So anyways, that's what I think I have but I'd really appreciate your thoughts on this. Ya'll have a lot more experience with these thing than I do so I welcome your opinions. Thanks!

I have a fossil hunting friend, who keeps very little of what he finds. Anything that has serious issues goes back to the fossil gods or into the bone garden at home. To make it into his collection, it must be exceptionally good. I am not like that... I keep almost everything... to analyze and toss later maybe, but initially keep it. He keeps very few fossils, which has its advantages. We sort of have a deal... anything he does not want (in certain categories) he saves for me.. I do what I can to repay the kindness. One of those categories is whale: He gave me this one last week It is a 4.25 inch Florida whale tooth, likely Kogiopsis. My question relates to the composition. The species seems to have no enamel, so originally this was dentine, surrounded by cementum. It is a land find from a construction site in Florida. I have similar teeth with this composition from the Bone Valley phosphate mines. To show a different Kogiopsis tooth, found in the Peace River, with a different composition: It is what I call "hard" composition... So the questions: 1) Is this composition unique to Florida? Do other TFF members who find whole/broken whale teeth (or any other fossil) have this type of composition in their fossil collections? 2) What is the composition and the process that creates it? Thanks, Just driven by curiosity. Jack

Is this a bone, and if so what kind of bone is it and maybe what kind if animal could it have came from? For context it was given to my grandfather by his brother in Arkansas a long time ago. Any help would be greatly appreciated

New Brunswick Museum's Steinhammer Research Lab (Day In Saint John, New Brunswick, Canada)
redleaf101 posted a topic in Fossil Hunting Trips
Hey there! I know I know, I've been missing in action for the past few months. Work and Field work kept me busy. But I've now am taking the time to update my blog, and sharing some of my recent adventures. This one is not so much of a fossil hunting trip, but of discovery on fossil history in New Brunswick. A few weekends ago I went for a day trip to Saint John to meet up with my friend Matt at the New Brunswick Museum's Steinhammer Lab. He's currently doing a stint at the research facility and I couldn't resist, desperately wanting to tour this historic place. This building was the original New Brunswick Museum until it needed more space to accommodate a growing collection. In the 1990s, the exhibition displays found a new home downtown (Market Street area), but most of its collection (closed to the public) was kept at the original building on Douglas Avenue. This museum is considered Canada's oldest, housing collections dating back to its first proprietor, Abraham Gesner. The influence of the Steinhammer Club, comprised of geologists from the area and abroad, was pivotal in the history of Geology across the globe. They founded the Natural History Society of New Brunswick, and from there the contributions to science have been crucial to the advancement of several fields. I had also wanted to meet up again with Dr. Randall Miller, curator of the collections and museum, but he was currently out of town. I arrived at the old museum in one piece after dodging a hellish traffic and weird road designs. Beautiful city, crappy roads. Matt making sure Steve is hard at work I got to the museum and after talking to the wonderful staff, I met up with Matt and one other friend, Steve. Steve is an amazing fella and will keep you on your toes. They were in the middle of taking specimens collected in recent field work (a couple that I've participated in) and offered to lend a hand. We unloaded the material to the lab, and headed out for a bite to eat. After parting ways with Steve as he headed back to Fredericton, we proceeded in taking a tour of the Steinhammer Palaeontology Lab. I didn't take any pictures as Randy wasn't around and didn't want to take any just in case he didn't approve. Going through the collection, I've seen some incredible representations of various paleobiological and paleobotanical specimens, including many type specimens. Trilobites, which a cast of one of the biggest I've ever seen barely fit in the collection cabinet. Eurypterids, or sea scorpions, that could give you nightmares, were the size of your average family dog. Fish, bones, and even the remains of a wooly mammoth (Mastodon) graced the collection. This animal was collected from the Hillsborough area, near where I live. The tusks were incredible to behold. Walking through the halls, it was easy to get lost amidst the many artifacts laying around, beckoning, hungry for your attention. Even going to the washrooms you have to pass a wall of jars, each filled with animals living, and extinct. One doesn't linger too long in the bathroom let me tell ya. Also among the specimens at the lab were the many trackways that we collected, waiting to be analyzed and studied. Seeing specimens that you helped bring up in the light of day and residing in this place was quite a special feeling. As the day winded down, me and Matt chatted about the importance of keeping collections together, and the crucial role that these play. Every effort must be made to help save these as they help us understand our past and help dictate a future most rich. Our friend Margaret arrived near the end of my stay. As we said our goodbyes, I felt that it was imperative that I participate in the discovery and safekeeping of fossils, and to contribute in the advancement in the fields surrounding those of paleontology and biology. That is why I love geology, as it makes me have an intimate rapport with science, to which I love and am passionate to no end. To understand and comprehend, wonder even for what nature has left in our path, often hidden, for us to uncover and rediscover. Cheers! - Keenan Saint John River, view from behind the museum- 5 replies

Could this contain fossils possibly or is there just crystals in it?
Ago13 posted a topic in Fossil ID
I might be wrong, but I believe that this rock is sandstone (if it isn’t please correct me) and that the spots in it are feldspar. I was wondering why there is such an odd placement of the feldspar(if it is feldspar) and it made me wonder if there could be fossils in it. I was planning on putting it in a rock tumbler to see if it would turn out good, but if there are fossils in it, wouldn’t it be better to work on the rock and uncover them instead of just polishing the whole rock. If you think that there could be fossils contained in it, what could it possibly be? If not, no worries I’ll probably just toss it in my rock tumbler and see what happens to it lol. (Btw it was found on cannon beach in Oregon about a year ago for context)

Here are some photos of a geology site near to where I live. The cliff is of the Thornhill rock formation (upper Carboniferous). It was formed in a meandering river channel. I haven’t seen any fossils in the sandstones, but there are some very poorly preserved plant remains in the siltstones. Most of the fossils I find in the coal measures are from coal tips, so even though this isn’t a fossil site, I enjoy visiting here to see the geology.

Licking dinosaur fossils: how does licking rocks help us identify them as fossils?
KrishnaRao10 posted a topic in Questions & Answers
Greetings kind people, I'm so sorry if this is such a noob question. But I've searched and searched but I couldn't find answers to these on internet. (kindly correct me because I feel I maybe wrong): Smithsonian website said licking dinosaur fossil helps in identifying between a rock or a fossil... But isn't fossil a rock in itself? Fossils are made because minerals get replaced and it's not possible for bone to remain in its original state for millions of years. So, it's not the original material anymore.. so licking a fossil should equal to licking a rock? In that case, licking should not work? -
Hello together, Something I quite often see in the ID-section are pseudofossils commented as "geological/rock". I dont want to be nitpicking, probably it´s just short for "purely geological". Simply "geological" doesn´t seem opposed to fossil, in my understanding fossils do happen at the interesection between geology and biology. So "no biologic structure"=no fossil (except chemical fossils) , but "geological" seems to apply to all the specimens (if they are not molten plastic, recent bone, or something else entirely. ) English is not my native tongue as you may have noticed, but in my understanding fossils are also rocks, at least some kinds, for example steinkern preservation, (rocks with) impressions... So it may be confusing especially for the newbies that often ask about pseudofossils if "geology" stands as the opposite of fossil. What do you think? Best Regards, J

Well, in my research to find a fossiliferous bed near me I have been struggling with the geology, and spending days driving around observing, taking notes and pics. Well, I just found a published paper from one of the original paleontologists. In it, he lists the location of each outcrop, but this leads to more confusion. When I track the T,R,S locations listed, there is nothing there. Every promising site I found while scouting is clearly visible on satellite mapping. When I look up the listed spots, I find NOTHING. It's just plowed farmland. I find zero evidence of buttes, mesas, draws, cuts or anything that could be an exposure of the formation. I've obviously got to do some more "boots on the ground" stuff, but I'm not feeling hopeful for the listed sites. Maybe I'll start by investigating any outcrops closest to the listed locations.
