Drone assisted meteorite recovery - My Question: Why not Drone assisted vertebrate fossil recovery?
Oxytropidoceras posted a topic in Fossil News
If a person can find meteorites with drone, Why not vertebrate fossils? In the case of fossils, geological maps and aerial images take the roles of the radar and satellites used for meteorites. Drone assisted meteorite recovery Global Fireball Observatory, March 14, 2022 How satellites, radar and drones are tracking meteorites and aiding Earth’s asteroid defence Hadrian Devillepoix, The Conversation, November 21, 2022 An early attempt at using drones to find fossils: Archaeologists are hunting for fossils in Kenya's Turkana Basin — and you can help The Week, September 11, 2015 I have yet to find any publications that resulted from this research except for "Fossil Finder - the next stage. April 2018 Update. There is "field guide" on the righthand side that shows what fossils look like in an aerial drone image. Yours, Paul H. -

New Investigation of a Greenland ice core platinum anomaly near the Bølling-Allerød/Younger Dryas boundary
Oxytropidoceras posted a topic in Fossil News
Green, C. E., 2019. Investigating the origin of a Greenland ice core geochemical anomaly near the Bølling-Allerød/Younger Dryas boundary (Doctoral dissertation, Durham University). http://etheses.dur.ac.uk/13490/ http://etheses.dur.ac.uk/13490/1/C_Green_thesis_final_CORRECTIONS.pdf Green (2019) noted: "The source of a platinum peak identified in the Greenland Ice Sheet Project 2 (GISP2) ice core associated with high platinum/iridium (Pt/Ir) and platinum/aluminium (Pt/Al) ratios, and previous research attributed the anomaly to an unusual iron-rich Ir-poor meteorite impact." Green (2019) concluded: I. the Laacher See eruption is not the Pt spike source because: A. the Laacher See tephra has low Pt concentrations, B. the Laacher See tephra’s geochemical ratios are dissimilar to the GISP2 Pt spike and C. conversion of the Pt spike timing to the newest ice core age-depth model shows a chronological offset of ~60 years between the two events. II. The event resulting in the Pt spike occurred ~60 years after GS-1 cooling, and was therefore not the primary trigger. III. and the Pt spike origin is interpreted as either: A. a noncataclysmic impact of an undiscovered iron meteorite B. or an unidentified Pt-rich volcanic eruption contemporaneous with the anomaly, whose aerosol fractionated in the atmosphere or ice.

Aloha, here is the best of my collection. Since I moved together with my girlfriend, only the small and nice samples are on display, one showcase out of three. Looking forward to the day when we will have some more space. So it is a crowded mix of fossils, minerals, recent beachfinds and mosty selfmade or altered skeleton models. Sadly, only a small percentage of my fossils is selffound, although nearly all of the beach stuff is. There is the "poultry showcase", dedicated to Birds and pterosaurs (Parrot skull is a replica of course, as is the Pterosaur plate regrettably) The big showcase is a composite image because I could not get all into one foto. The whales you may know from the Palaeorecreation thread. Best Regards, J

Hello, I am ziggycardon! I am currently 23 years old and I'm from Belgium. Ever scince I was a small child, I've had a great interest in dinosaurs, animals and pretty much everything that has to do with nature and natural history! On a professional level I also work with animals as I am head of terrarium & aquarium in 3 different pet stores, but in my spare time I also keep and breed many reptiles, amphibians, invertebrates & exotix fish (although, I am tyring to take it a few steps back privately), and another thing I do in my spare time is to visit school with my collection of reptiles and other exotic animals (including some living fossils) as well as a whole load of other educational natural history material and ofcourse with fossils. One of my biggest interest in evolution and that's where my passion for the paleontology and zoology really meet! I bought my first fossil at the age of 12, but I've started collecting fossils as a hobby in late 2015 and I have build a small collection ever since. Unfortunatly I have never in my life found a fossil myself, something I really have to start doing as I find the entire process fascinating, but I am sure this forum might give me the push I need to get started! This week I started working on my first specialized fossil room which I hope to have finished in november this year. Hope to house most of my fossils there as well as some museum quality replica's and do some themed displays like a Kemkem display with a life sized spinosaurus skull replica and lot's of kemkem fossils, a ice age display, a eocene display, a marine reptile display and so on... Something I also wanted to mention, the reason I've found this forum is due to the fact that I had a 1,06 meter long lower jaw of a Prognathodon delivered today and the seller of the fossil who brought me the fossil told me about the forum after I told him about the upcoming fossil room and that I might get in contact here with people should I ever want a certain fossil that might be hard to uptain. Is there anything more to say about me? Well I've the most wonderfull girlfriend I can imagine who shares an interest in paleontology but not in the same passion as I do. I really love to visit musea and I love to travel. And besides fossils and animals my other hobbies & interests are centered about movies and television as I am in particular a huge fan of everything Middle Earth, Game of Thrones & Pirates of the Caribbean, collecting lot's of collectables from these franchises and met quite a lot of the actors who play in them! Including Sam Neill who we probably all now best as dr. Alan Grant in Jurassic Park! Here are some photo's of my fossil collection, my animals and my photo with Sam Neill. First of all, this is me proudly posing with an ammonite! My newly arrived prognathodon jaw My display cases: afbeeldinegn upload images afbeeldingne upload pictures img foto The things that I don't have room for to display yet... A few of my special pets My photo with Sam Neill A.K.A. dr. Alan Grant If you have any questions regarding my photo's or my collection or what I do or about anything, feel free to ask!

This could suggest opalised microbial fossils on Mars...
The Amateur Paleontologist posted a topic in Members' News & Diversions
In 1911, near the Egyptian village of El Nakhla El Baharia was recovered a meteorite of martian origin. It belongs to a class of martian meteorites (called "nakhlites") that are derived from a ~1.3 billion year old sill or lava flow. They are mainly composed of magnesium, silica and iron. The Nakhla meteorite showed traces of a very particular form of silica, hydrated and amorphous: opal. This opal was the first in a few traces of martian opal. However, the hydrated silica in the Nakhla meteorite showed showed something rather special: it was very similar to the sort of opal that, on Earth, forms around hydrothermal vents. Around these vents, microbial life thrives and prospers. Could this suggest opalised microbial fossils on Mars? Are we this close to finding fossil life elsewhere in the universe? Further research will tell...- 6 replies

Hey TFF, I have been collecting meteorites for a few years now and since I am saving up to buy a new fossil, I would like to sell some of meteorites. Would you guys know where to sell meteorites? Thanks!!
