    Going to Wonderland

    I know that I went hunting yesterday. My neck and back muscles are screaming at me. We go to places we have visited before... In this case, some sort of coral reef or shell bed that was laid down , most likely in the Pliocene. Steve, who worked in the Phosphate mines said that there were 3 layers of shell beds in Bone Valley mines where he worked. Land mammal remains between the shell layers. In some locations, the Peace River has brought those layers close to the surface. I call this location wonderland. When ever I go there ... I wonder.. I wonder what layer I am finding.. Pliocene ? Miocene, whatever the 1st layer is... I wonder what process created what I see.... I went back in TFF to find that I have not revisited this location in more than 2 years. Back to the yesterday, A Barnacle.... This is solid rock... or blended silica with sand , mud , shell ..I wonder if the Barnacle "shell" filled with sand or mud and the silica transformed the whole thing to rock, sand mud , everything.. and I always wonder about the process details... Shells..... ..I wonder if we can identify the shells because that might tells us if there were Pliocene or Miocene.... I wonder about the process details... This is not hard fossilized rock like the barnacle... This is like mud rock,, that would break or crumble pretty easily So the shells existed on the bottom of the ocean, the ocean receded, Peace River brings in fresh water, somehow it is making mud-rock (which is common in many forms)... the shell sticks to the mud rock, then the silicification comes along changing the shells ,not the mud-rock., and the whole thing gets worn down until I pick it up.... Shell # 1 2nd Shell ..The rock weighs 40-50 pounds... a heavy item on the trip back in my kayak..Is this whole bivalve there ? Was this one transformed to Silica.... I wonder ... I also find botryoidal chalcedony, some bigger... some smaller. I think this formed in a "cave" in a echinoid sand dollar... Finally for those who appreciate more traditional Florida fossils, I found some of these also. Really like this tooth, it exihibits serrations with feeding damage and those CUSPS !!!... I wonder if if cusps on Megs is only true of Pliocene Megs. I am sad to say that it looks like the chipped the root on recovery. I guess what it comes down to is I am a wondering kind of guy....Enjoy

    Giant deep water barnacle

    Here’s something a little different. For years we’ve occasionally found remains of these giant barnacles on the beach at a Miocene site here in New Zealand. I wasn’t sure of the ID, or where exactly they were coming from. It was a bit of a mystery. A few weeks ago we went exploring in an area we hadn’t looked before and found a layer, where the only fossils are these barnacles! There is enough exposed to get a genus: Bathylasma. A deep water barnacle. In NZ the modern species Bathylasma alearum lives in water depths from 400-1600m. I collected this beauty, and just finished roughing it out today. It’s in softish Siltstone so can be prepped with a needle, brushes etc. I’ll update as prep progresses

    Barnacle?

    This is from the Platteville formation. Is it a barnacle? I'll buy a ruler tomorrow lol. Thanks for all the help today!!

    Coral? Barnacle? Fossil?

    Any help identifying this is appreciated. Pretty sure it’s a fossil of coral, barnacle or some other similar sea life but I really don’t know. Like my other posts, comes out of the Florida estate fossil collection that I purchased at auction. Once again thank you all in advance for any help.
  6. Hello there! Found this guy in Calvert cliffs state park, Maryland. I think it's a fossilized barnacle, but I'd love another perspective. Thanks in advance and I appreciate the help!
  7. Two species? Photos for specimen one are 1-7 and photos for specimen two are 8-13.

    Chiapas Amber Simojovel, Chiapas, Mexico La Quinta Fm./Mazantic Shale (Simojovel Group) 22.8-15 Ma Specimen (Rough): Weight: 11.8g Dimensions: 33x31x17mm Lighting: 140lm LED Longwave UV (365nm) About the Specimen: A thick, red oxidized layer was formed over millions of years through oxidation during the amber's burial. The blue-green fluorescence is due to exposure of the amber's hydrocarbons to UV wavelengths in the LED light. There are numerous fossil barnacles and barnacle scars, coating the exterior of the specimen. History: The amber of Chiapas has a history of use that dates back to the age of the Maya Empire; amber was traded between different tribes, and sometimes sent as an annual tribute to other nations (i.e., Aztec Empire). It was frequently fashioned into ornaments and jewelry such as necklaces, as well as lip, nose, and ear plugs; living descendants of the Mayan civilization carry on this ancient tradition, and skilled artisans fashion amber into similar jewelry, and sculptures of intricate detail. Botanical Source: Through Carbon-13 Nuclear Magnetic Resonance Spectroscopy, as well as the presence of fossil leaves and flowers, the source trees of Chiapas amber have been identified as two extinct species belonging to the Hymenaea genus (Subfamily: Caesalpinioideae): H. mexicana and H. allendis; both trees are related to H. protera, which produced Dominican amber. The closest living relative of these three extinct genera is H. verrucosa, which is native to East Africa. Geology of Deposits: The Sierra Madre del Sur contains three amber-bearing Formations, beginning at the youngest: Balumtun Sandstone, Mazantic Shale, and La Quinta Fm.; amber is most frequently found in the Mazantic Shale and La Quinta Formations, and is associated with layers of lignite, and found in calcareous marine sandstones, siltstones, and shales. Amber specimens up to 60cm long are known to occur at the Campo La Granja mines.

    Chiapas Amber Simojovel, Chiapas, Mexico La Quinta Fm./Mazantic Shale (Simojovel Group) 22.8-15 Ma Specimen (Polished): Weight: 11.4g Dimensions: 30x31x17mm Lighting: 140lm LED About the Specimen: This is the same specimen from other entries, but with polished faces that were once broken. The thick, red oxidized layer was formed over millions of years through oxidation during the amber's burial. The blue and blue-green fluorescence is due to exposure of the amber's hydrocarbons to UV wavelengths in the LED light. An excellent display of color zoning, this close-up image better shows the transition between oxidized and unoxidized layers, as well as strong fluorescence under LED light. History: The amber of Chiapas has a history of use that dates back to the age of the Maya Empire; amber was traded between different tribes, and sometimes sent as an annual tribute to other nations (i.e., Aztec Empire).

Botanical Source: Through Carbon-13 Nuclear Magnetic Resonance Spectroscopy, as well as the presence of fossil leaves and flowers, the source trees of Chiapas amber have been identified as two extinct species belonging to the Hymenaea genus (Subfamily: Caesalpinioideae): H. mexicana and H. allendis; both trees are related to H. protera, which produced Dominican amber. The closest living relative of these three extinct genera is H. verrucosa, which is native to East Africa. Geology of Deposits: The Sierra Madre del Sur contains three amber-bearing Formations, beginning at the youngest: Balumtun Sandstone, Mazantic Shale, and La Quinta Fm.; amber is most frequently found in the Mazantic Shale and La Quinta Formations, and is associated with layers of lignite, and found in calcareous marine sandstones, siltstones, and shales. Amber specimens up to 60cm long are known to occur at the Campo La Granja mines.

  17. Aloha, I just got myself a cristmas present, not that old, but to beautiful to resist. A fossil shell from Florida, encrusted in barnacles. I havent got it yet, so here are two pics from the seller. Who can tell me a species or even two? And an age, or is it all holocene? Best regards, J

    Microfossil goose barnacle?

    So, one more for now from the kids museum I created when I was 12. This is an extraordinarily small fossil I found by cracking open some rocks on a rock outcropping when I was a kid. The appearance reminds me of modern day goose-neck barnacles but I default to your opinions- species and age always appreciated! Stay healthy! Bone

    Need help with Barnacle!

    Hello, can anyone please help me with this Barnacle. Is this old? Do you have any idea of the age of this or if a fossil even or just a dead barnacle shell. Its about 2 inches the shell its self and about 1 1/2 depth. It was found in Oregon, United States (Pacific Ocean Beach)
  20. Ahoi dear forum members. While reading a little bit about rudists some of the structures in picture of a broken Hippurites and the shape of Lapeirusia crateriformis reminded me remotely of a still unidentified beachfind from my last big holiday. That doesn´t say much, as apparently rudist could look like anything they wanted, but still I wonder what the fragment I found may be. Found it in the pacific driftline, broken like you see it. There are some barnacles, some serpulids, maybe a little bivalve also, but I wonder what the enclosing structure is. Any ideas? Aloha, J

    MIOCENE ISLAND

    I should have posted this long ago, but am going to do it now, in the hope that then it is behind me and then I can look forward to future adventures. Due to ill health from 2012, finances and responsibilities, I have been unable to do any personal collecting except for this one wonderful trip which reminded me that I've still got it in me. In October 2016 wifey and I were relaxing in a bar on Tarifa beach, the southernmost point in mainland Europe, located at the south-western corner of Spain, opposite Tangier, the two Pillars of Hercules that are the entrance to the Mediterranean from the Atlantic. I noticed an island connected to the mainland by a man made causeway. it had a lighthouse on and some ruins, so I thought that being only a little distance, I'd go and explore. Here is the location, to the left of the picture is the Mediterranean, to the right, the Atlantic. There are no more location pics, I'm afraid, as wifey can't be prised away from bars very easily and she has the camera phone, but the island was closed to visitors without a guide or permit as it's a place for protected birds, the lighthouse and Napoleonic fortress ruins. But to the left of the causeway was a small beach with exposed rocks and even a little notice board explaining that the rocks were a Miocene oyster bed 5 to 10 million years old. My interest was aroused so I clambered about the beach and found the fossils in the next post. Very pleased with myself, I was, especially as I had no tools and the rock was really seriously hard. Had to use other bits of rock as hammer and chisels. And my breathing held out pretty well. I can still do this! Life's Good.

    Matoaka Beach - 12-02-18

    Took a trip to Matoaka Beach for the first time today. Alot of bivalves, barnacles, couple pieces of coral, and one snail. Here's a pic! No sharks teeth but I will keep trying! IMG_1322.HEIC

    Agatized Barnacle

    From the album: ocean stuff

    Here was a nice surprise. I picked up this fossil cluster of barnacles and noticed a nice layer of agate underneath! When I processed the photo I took of it I saw that the light from my flash dispersed giving this rainbow effect. It's very small but now when I hold to the light I can see the little rainbows!

    Barnacle

    Found on the beach near Matoaka Cabins. This is the largest one I have found to date.

    Concavus concavus

    Barnacles are very abundant at some exposures in North Carolina. So at these places( and this was one of them) it takes a unique specimen for me to pick it up. This one caught my eye. Rather large and complete, plus has a natural display "seat". C. concavus is kind of a catch all for many barnacles that are found in the Pliocene.
