  2. Chinese bird with preserved (?)lungs

    This is rather interesting - a specimen of the bird Archeorhynchus spathula (STM7-11) from the Lower Cretaceous Jiufotang Formation (northeastern China) has been shown to have probable evidence of preserved lungs Wang, X., O’Connor, J. K., Maina, J. N., Pan, Y., Wang, M., Wang, Y., Zheng, X., & Zhou, Z. (2018). Archaeorhynchus preserving significant soft tissue including probable fossilized lungs.

  3. I found this plate of oysters I don't know the name of in the Lower Cretaceous Grayson Formation exposure at Rayzor Ranch in Denton Texas. I showed it to @trempie4 in August and @Jeffrey P when he was here in September and neither one wanted it so I finally took it home myself. As I was exposing more of the oysters I first noticed these nice little serpula on and around the oysters. Then I noticed something I haven't seen before. i wonder if it could be some kind of feeding trace. Any ideas?
  4. Lower Cretaceous form

    Found this little item in my rock bar that has me stumped. Has too much form to be a "concretion", but not enough to try to get a bone ID. It came from a Maryland Creek in the Arundel "formation" Potomac "group".
  5. Ironstone from MD

    I will leave this without comment also, for your interpretation.
  6. Arundel/ Patuxent find

    I will leave this for your interpretation without comment.
  7. A couple of relatively nice Oxytropidoceras sp ammonites I found on a spring hunt with the Dallas Palaeontological Society to Oliver Creek in Denton County, Texas a couple of years ago.
  8. An interesting discovery in Japan https://www.japantimes.co.jp/news/2018/02/04/national/science-health/cranial-bones-three-horned-dinosaurs-found-western-japan/
  9. I saw this article earlier today. If someone has already posted it I give my apologies for reposting it, but I think it is an interesting article on: “A diverse mammal-dominated, footprint assemblage from wetland deposits in the Lower Cretaceous of Maryland” It is published in Nature. https://www.nature.com/articles/s41598-017-18619-w

    From the album MY FOSSIL Collection - Dpaul7

    Loriolia echinoid Fossil SITE LOCATION: Comal County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Loriolia is a genus of extinct sea urchins from the Emiratiidae family. The Emiratiidae are a family of extinct sea urchins (Echinoidea) of the order Phymosomatoida. The Phymosomatoida are an order of sea urchins, found in Europe, North America, North Africa and the Middle East. They are distinguished from other sea urchins by the presence of large fused plates on top of the feeding lantern. The test is usually sculpted to some degree, but, unlike their close relatives the Temnopleuroida, the tubercles are never perforated. The opening in the test through which the anus passes, known as the periproct, is unusually large in sea urchins from this group. The apical disc, around the mouth, is only loosely attached to the rest of the test and is often missing in fossil species, giving the false impression that they also have a large oral opening Kingdom: Animalia Phylum: Echinodermata Class: Echinoidea Order: Phymosomatoida Family: †Emiratiidae Genus: †Loriolia

    From the album MY FOSSIL Collection - Dpaul7

    Tapes decepta Mollusk Cast SITE LOCATION: Glen Rose Formation, Bandera County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago. Although the group became increasingly abundant about 400 million years ago during the Devonian Period, bivalves really took off following the massive extinction at the close of the Permian Period. Modern bivalves live in a variety of marine and freshwater environments, from the shallow waters near shore to great depths in the ocean. Fossils indicate that bivalves have occupied most of these environments for more than 450 million years, but during the Paleozoic Era they were especially common in near-shore environments. The Veneridae or venerids, common name the venus clams, are a very large family of minute to large, saltwater clams, marine bivalve molluscs. Over 500 living species of venerid bivalves are known, most of which are edible, and many of which are exploited as food sources. Many of the most important edible species are commonly known (in the USA) simply as "clams". Venerids make up a significant proportion of the world fishery of edible bivalves. The family includes some species that are important commercially, such as (in the USA) the hard clam or quahog, Mercenaria mercenaria.

    Heteraster texanus Echinoid SITE LOCATION: Commanche Park Formation, Mills County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Heteraster is an extinct genus of sea urchins belonging to the family Toxasteridae. These slow-moving shallow infaunal deposit feeder-detritivores lived during the Cretaceous period. Fossils of this family have been found in the sediments of Algeria, Egypt, France, Hungary, Mexico, Peru, Portugal, Serbia and Montenegro, Spain, Switzerland and Yemen.

    From the album MY FOSSIL Collection - Dpaul7

    Kingena Brachiopod SITE LOCATION: Main St. Formation, Johnson County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Kingena is an extinct genus of brachiopods that lived from the Cretaceous to the early Paleocene in Antarctica, Europe, North America, and New Zealand. Terebratulids are one of only three living orders of articulate brachiopods, the others being the Rhynchonellida and the Thecideida. Craniida and Lingulida include living brachiopods, but are inarticulates. The name, Terebratula, may be derived from the Latin "terebra", meaning "hole-borer". The perceived resemblance of terebratulid shells to ancient Roman oil lamps gave the brachiopods their common name "lamp shell".

    From the album MY FOSSIL Collection - Dpaul7

    Texigryphaea marcoui bivalve SITE LOCATION: Mills County, Texas, USA TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: Gryphaea, common name Devil's toenails, is a genus of extinct oysters, marine bivalve mollusks in the family Gryphaeidae. These fossils range from the Triassic to the Tertiary periods, but are mostly restricted to the Triassic and Jurassic. Both periods belong to the era Mesozoic. They are particularly common in many parts of Britain. These oysters lived on the sea bed in shallow waters, possibly in large colonies. The complete fossils consist of two articulated valves: a larger gnarly-shaped shell (the "toenail") and a smaller, flattened shell, the "lid". The soft parts of the animal occupied the cavity between the two shells, just like modern oysters. The shells also feature prominent growth bands. The larger, curved shell sat within the mud on the sea floor. These shells are sometimes found in fossil plates along with Turritella, clams, and sometimes sharks' teeth and fossilized fish scales. Its distribution is common in areas of both Europe and North America. A classic location to find these fossils is Redcar, on the northeast coast of England. There used to be a common folk belief that carrying one of these fossils could prevent rheumatism. They are also found in abundance in the state of Kansas in riverbeds and cliffs as well as the Big Horn Canyon of Wyoming and Montana. The benthic, free-living oyster Texigryphaea was the dominant constituent of many late Albian marine communities in the Texas and southern Western Interior regions. Large topotypic assemblages of three common lower–middle Washita Group species (T. navia and T. pitcheri in Oklahoma and T. tucumcarii in New Mexico) each display considerable morphological variation in valve shape and the proportions and expression of various features. Variation within an assemblage is partly due to ontogenetic changes but is mainly ecophenotypic, with local variation in nature of substrate, water turbulence, length of attachment time, and other factors influencing the final morphology of the mature shell.

    Ilymatogyra ram's horn oyster fossil SITE LOCATION: Del Rio, Texas TIME PERIOD: Lower Cretaceous (100-145 million years ago) Data: The Gryphaeidae, common name the foam oysters or honeycomb oysters, are a family of marine bivalve mollusks, and are a kind of true oyster. This family of bivalves is very well represented in the fossil record, however the number of living species is very few. All species have shells cemented to a substrate. Shells are considered brittle, inequivalve, with the left, lower (cemented) valve convex and the right (upper, non-cemented) valve flat or slightly concave.

  23. Ammo Pendent

    Got a pretty little ammo pendent yesterday. Funny how I live in Florida but do not own any shell fossils,nor a single sharks tooth. I guess they are just so plentiful around here that I never kept any. Anyhow,back to the pendant. The guy I bought it from had little to no knowledge outside 'it's a shell,it's opalized,it's 5 bucks' So after some personal research I think I have a...... Cleoniceras Cleon Lower Cretaceous Madagascar It's 1 inch at its widest. Now,other than confirmation of ID, I'm wondering what the tiny spiral inside the opening is. Is it another teeny tiny ammo or just junk that settled inside as it fossilized.
  24. Fruiting body?

    I found this a while back in the lower Cretaceous. I'm not sure what it is. It looks like a fruit of some sort. I've never found anything like it. Mostly what I find are ammonites, gastropods, bivalves, brachiopods, corals and such. I have not totally cleaned it up, because I found these little nibs on the surface and I'm not sure if they're part of the structure or not. Also what I think is the top or stem area is very tough and I'd hate to ruin some fine feature if it's there. I'd like to know what it is supposed to look like before I finish it off. I'm a novice so I don't really know good techniques for cleaning off the stuff encrusting it. Hopefully I'll improve with practice. I'm eager to learn, because I've got a lot of cool fossils still encased in crud I'd like to remove if I knew a good way to go about it. It's about 2 cm in diameter. The first 2 shots I took on a mirror so you could see the top and bottom/side in one shot. Any help would be appreciated.
  25. FYI.....Amazing.... Abstract: A new fossil mushroom is described and illustrated from the Lower Cretaceous Crato Formation of northeast Brazil. Gondwanagaricites magnificus gen. et sp. nov. is remarkable for its exceptional preservation as a mineralized replacement in laminated limestone, as all other fossil mushrooms are known from amber inclusions. Gondwanagaricites represents the oldest fossil mushroom to date and the first fossil mushroom from Gondwana. Heads SW, Miller AN, Crane JL, Thomas MJ, Ruffatto DM, Methven AS, et al.
