Jung, P., Baumann, K., et al. (2020). Desert breath—How fog promotes a novel type of soil biocenosis, forming the coastal Atacama Desert’s living skin. Geobiology 18:113–124. PDF Of interest to those who study/like to know more about: - the varied ways in which Earth's biota influences/can influence the surface of our planet - exobiology - Precambrian geology - soil formation and preservation - the interaction between edaphic (geomorphology,precipitation)factors and microbiota - geomorphology - the global carbon and nitrogen cycle - ecosystem formation Skippables: page 114 to part of page 117 are mostly methodological(although I found the remote sensing part interesting) wraasamolovJungbendix_al-aridesatacamericabsol2020Geobiology.pdf

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.

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

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.

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 !)

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.

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!

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?

Fossils from the negev desert in israel and a fossil shark tooth from the east coast
mattbsharks posted a topic in Fossil ID
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. -
Would love help identifying which species this bone belongs to- I think its a cuneiform bone but of what mammal?

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

I found this on a desert hike today

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!!

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

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!

Mojave Desert Coral - Trachyphyllia Or Heliophyllum? And An Unknown Fossil
z10silver posted a topic in Fossil ID
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 -
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

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
