  1. Crocodile Egg or Sea Urchin?

    During a trip to Egypt I found this potential fossil near the city of Aswan between the banks of the Nile River and Sahara Desert. I had thought it might have been a meteor and the sand fused around the meteor due to the Intense heat. But, I tested it with a magnet but there was absolutely no attraction. Therefore, I thought it might be a fossil given that I read about many fossils being discovered in the Sahara and the composition does appear to be any rock or stone that I've ever encountered. I assumed crocodile due to the spiky and bumpy texture, along with the historic prevalence of crocodiles in that region. What do you think this is? Thanks!
  2. Worm Creature from Arizona Desert

    Hello, I have been finding all sorts of neat rocks and marine fossils in the desert outside of Yuma, Arizona where the Colorado river had once flowed into a large ocean. There seems to be some sort of worm creature fossilized in this stone? I would appreciate an ID on the specimen, or speculation as to what it is? Thank you.

  5. Merzouga - Sahara - Morocco

    Day One ; Locality Five Sahara Desert 19th February 2019 An advert for Erfoud, the fossil capital of Morocco. But no time today, the sun is setting. "Tomorrow", Anouar promises me. And then suddenly we are out of the mountains and on the fringes of the mighty Sahara Desert, the largest hot desert in the world. (Antarctica and the Arctic are bigger, but cold deserts) Many think of the Sahara as being sand, but actually, only a fraction of it is composed of the ergs (sand and sand dunes), most of the desert is hamada - rock desert. It is often fossiliferous. In the west, around Agadir, it is often yellow and contains Cretaceous fossils such as ammonites, south of there, the whitish yellow rocks of the Palaeogene where whale fossils can be found in the desert, but in the east, such as here, the rocks are often grey or black , hence the term, "Black Sahara". They range in age from the Precambrian stromatolite reefs near Ouarzazate through to some Lower Carboniferous patches North of Merzouga near Erfoud. Here in Merzouga they are mostly Devonian in age. Also nodules and geodes containing crystals and desert roses and other strange geological features may be found. And those aren't mountains in the distance, those are sand dunes. The dunes of the mighty Erg Chebbi up to 150 metres high. But no time for collecting today. The sun was setting and it was time for dinner and a sleep. We were going to stay in a Berber desert nomad tent, but they're mostly a bit touristy and some have been forcibly shut down since i was there, but the temperature was going to be only i degree above freezing tonight, so, no thank you very much, a hotel it shall be.
  6. Petrified wood from California?

    I was wondering if anyone could confirm that these two stones are indeed petrified wood. I picked them up while camping west of the Salton Sea in southern california. There's 2 pieces for consideration: both were found in the same general area, a year apart. They feel like solid rock but show pores and prints that make me think it's petrified wood. If it is, would anyone want to guess family or age? Thanks in advance! Front Back Top
  7. Hello everyone I’m new to this forum. My name is Tom, I’ve been collecting crystal rocks and fossils from the dessert area of Egypt, Sinai & southern Israel since the 1990’s. The one pictured here was recovered long time ago, It was 80 meters into the ground while digging in Granit rocks (construction in the middle of the desert..) I don’t know much about this and would love to to hear from the experts. I have so many fossils that I don’t know anything about, I’m planning to sell some to fund my college 2nd degree, so any info will be great. I’m very happy I found this forum Thanks in advance and I wish you all great day. Tom.
  8. Dear colleagues I found this strange small thin disk on the surface of the sand in the desert in Giza, Egypt (just outside Cairo). It's very thin and has concentric lines, each line being made up of small dots. I can't find anything like it on various fossil sites that I looked at. It's only 2.5cm (one inch) in diameter and very thin. Many thanks to anyone who has the time to reply, even if it's just speculation (it's fun guessing too !)
  9. Sea Shell

    Greetings Guys! I found this many years ago while on vacation in San Antonio Texas. I am quite the newbie relative to collecting and identifying fossils so some assistance would be greatly appreciated. I have tried to do some research on my own instead of jumping right on here with questions, but am stumped at this point. Below is what I think at this point. It was found in the hill country of midwest Texas out of San Antonio. I really don't know how to date it by periods of time, or the other definitions, but any help would be greatly appreciated. And sorry, this seems to be the best pictures my camera would shoot. Joe ------And this is my best guess. ---from the Cretaceous period, ---Western Interior Seaway Kingdom: Animalia Phylum: Mollusca Class: Bivalva Order: Family: Genus: Species:
  10. Any chance someone knows what these are? They are most probably Holocene-aged (last 12,000 years). They come from a dry playa lake setting (inland) in India - the Thar Desert. Size is about 1mm wide, and 1.5+mm long... there is a funny raised hollow insert. Would love to get some tips!
  11. Help two unknown fossils?

    Newbie here. I found these two fossils in my backyard in Pahrump, Nevada. One appears to be a crinoid, but I don't know what the other one is. Is it even a fossil? This is the high desert area 65 miles west of Las Vegas. Can anyone help me please?
  12. These first two fossils I picked up while hiking mountains in the negev desert in Israel. I think one of them is a sea shell with a barnacle on it. I'm not sure about the other tubular one. The final one is what I believe is some sort of mako.
  13. Tarsal bone id- Judean Desert

    Would love help identifying which species this bone belongs to- I think its a cuneiform bone but of what mammal?
  14. Saudi Arabia Fossil Website

    A good fossil website for those who happen to find themselves in the desert of Saudi Arabia (Me) and get the urge to hunt. http://afghan-arabiawild.com/Saudi Arabian Fossils Homepage.htm
  15. A Sonora desert museum dedicated to extant creatures of this desert, but having a mineral and fossil collection...some photos included, apologies about the flash flare on some of these images...
  16. Piles of Tree Looking Rocks

    Not at all sure what I'm looking at, but we're at my father-in-law's property in Arizona desertnear the river and we found lots of piles of rocks around that look like tree bark to me. Any help? EDIT: THIS IS THE LARGER ROCK THE SECOND PIC IS A DIFFERENT ROCK. For ID purposes I will label the large one Rock A and the smaller one Rock B. This is a pic of Rock A here:
  17. Is this a fossil or just a rock?

    I found this on a desert hike today
  18. Fossil Or Rock? Please Take A Look

    Hi, I found this in a bag of seashells at an estate sale. I actually bought the bag because of this specimen. I thought it looked very interesting with that perfectly round and smooth hole that runs through it. Is this a rock, a bone, or perhaps coral? Thank You!!
  19. Fossil Or Geofact?

    Found in southern NV the other day. Anyone know what this could be? Thank you!
  20. Coral? Flower? Sponge?

    Found this in Grandpa's rock pile..he collected rocks and miscellany in his tromps throughout Central and Eastern Oregon..he has passed so I have no idea where exacty he came upon this treasure... It is 6-sided chunk of 4 to 5-sided artifaces, seemingly attached in the center of the chunk, or not...some have closed "seed pods", one has open seed pod that look like kidney bean shape, perhaps like a flower gone to seed in stages...aprox 2.5 inches each side....there is not a hole in the chunk for anything looking like a stalk or stem...rings around the outer edges of each part suggest marine life, such as a shelled creature, though since it is stuck in a nice chunk package, not sure.... Any ideas??? Thank you!
  21. Found these two specimens in southern NV. Do you guys think they are Trachyphyllia or Heliophyllum? And how about this one? Some kind of shell? (note the 2 holes in the upper left portion of the fossil) Thanks, Zach
  22. Hey all, I found this shell out in the Mojave Desert (southern CA near the CA/NV border). I've found fossil shells out here before, but this one doesn't look like a fossil. I know that several thousand years ago there were permanent lakes out here - could this be from then? Or maybe a bird dropped it? Freshwater or marine? Thanks! Zach
  23. Mojave Desert Shell

    Hey guys, found this the other day in desert (southern CA near the CA/NV border). Can anyone tell me what it is, and approx. how old? Thanks, Zach
