    Aptian jetstone tree trunk

    First of all, hello everybody! This is my first post! Need some help with identification of a tree jetstone, site is an Aptian quarry, in north central Bulgaria. During few visits and alot of digging I managed to recover few chunks of a tree stem or a branch turned into jetstone. Can you help me identify the type of flora I have? I couldn't find much information online, and I don't have proper flora paleontology books. Attached photos below. Thanks! P.S. First 3 chunks i have treated with b72, the bigger ones are still natural condition. Also i have found some ammonites in the same quarry, might attach photos of them if whould help.

    Kimmeridgian derived aptian fossils

    Hi guys, I couldn’t find any literature on the kimmeridgian derived vertebrates of the Farringdon sponge gravels, I was wondering if anyone could help me with these or point out any literature 1. hybodus or asterscanthus? Notable for very large size! I wasn’t sure if size was diagnostic enough for a species identification 2. sold as a plesiosaur tooth but I suspect fish, does have striations @pachy-pleuro-whatnot-odon
  3. Hi there fossil collectors, this is my very first tooth, could someone please confirm this is an authentic spinosaurus tooth! thanks guys!

    British Wealden aigialosaur

    Hi all, I was recently told about supposed Aigialosaurus/aigialosaurid (mosasaurus) material from the Wealden at Bexhill-on-Sea in East Sussex, and was wondering whether anybody knows anything more about this. Because, as far as I'm aware (Wikipedia), Aigialosaurus is described from Hvar in Croatia and, moreover, temporarily restricted to the Cenomanian, whereas these remains, stemming from the Wealden, would be Early Cretaceous in age (Berriasian through Aptian) - most likely Valanginian, as they were recovered from Bexhill-on-Sea. (Image source) I must say these remains do look rather mosasauroid, although I've been unsuccessful in finding further information on the specimen, which is supposed to be housed in the Bexhill Museum. The person who first told me about them remembers having seen a newspaper article, believes the British Natural History Museum was involved with the specimen back then, and had heard about a paper being written about it. That's about all I have to go on for now. So my questions right now are: does anyone have more information on this specimen; know of the publication; and what do people here generally make of this piece: is it mosasauroid, or could it be something else? @paulgdls @DE&i @Praefectus @caterpillar @The Amateur Paleontologist @Kosmoceras @ThePhysicist @Welsh Wizard @DanJeavs

    Unknown Early Cretaceous Tooth

    Hi everyone! I was volunteering at Dinosaur Park (Laurel MD) this weekend for most likely my last time this summer as I’m gearing up to move in to a new apartment at college. I’ve missed 3 trip reports that I’ll probably add soon, for those who are following my thread on my visits or are interested. I ended up going out with a bang and breaking my surface collecting records by scoring my very first tooth and 4 bone fragments in 2 hours before calling it quits in the blazing heat. I was very excited, but the trouble is, we have no clue what it belongs to. I profusely apologize in advance for the lack of good quality photos. Even an attempt at an ID will be hard with little scale and bad lighting. I’m kicking myself over not taking more photos but we had to manage just under 500 people at the park due to the recent news and I was preoccupied. Hoping you all could weigh in at least to narrow down our options. I have attached all the photos I have of both sides of the tooth. I found it in a gravel wash (I spent 30 minutes scouring the area hoping to find more of the tooth) and it appears to be broken in half or at least missing much of the back and root. It has an interesting color and some sort of small inclusion on the surface of the tooth that I’m unsure if it’s concreted matrix or enamel or perhaps a bit of the jaw? It is a clear tooth, we do know this for sure. All at the park including our paleontologist have concurred on its toothy origins, we just don’t know what animal it belonged to. Our guesses are fish or lamnoid shark. I am hoping for the latter, because even though I really wanted to find a dinosaur tooth, it being a shark tooth would be a probable new species for the park.

  6. Hi everyone! 3-part excursion in the Cretaceous (Aptian) of Central Bulgaria, ~50Kms West of Veliko Tarnovo. 1st one reconnaissance with my girl on 18th of March. We did not stay a lot, poor finds mostly brachs and some echies. 2nd one, 24th-26th of March with friends. The majority of the finds are from this date. 3rd and last on 27th of May with one friend. The Urgonian complex of Bulgaria is a huge formation that extends many Kms around the cities of Veliko Tarnovo, Sevlievo and Lovech uninterrupted. The first findings were published during the Communist time, when lots of construction took place (road and rail infrastructure, a couple of huge water reservoirs, mining activity). If we would have to say something that stands out there and probably is known to people outside Bulgaria, it's well preserved regular echinoids. Many of you might have seen some being sold in Facebook groups for echinoids or some marketplaces. However, the Aptian Urgonian complex is not just echinoids; there is a huge variety of brachiopods preserved with their original "nacre". Even if you are not into them, trust me there you will start gathering them like cherries. Here we are parked on the first visit. The weather was pretty nice, ideal for such an excursion. Here is the main outcrop, on the second visit. I am nowhere in this picture; you see bad habit of not taking in situ. I will start with the brachs and leave the echies for another day since I am still cleaning them with KOH. On the other hand, the brachs were cleaned easily with ultrasound bath. Tried to group them in families, I am not even sure I am correct but anyway here we go: Terebratulidae: (The pictures are wrongly inverted, so the front side of the 1st on the upper row matches the last one on the lower row). Plate 1 Plate 2 Plate 3 Plate 4 Plate 5 From this picture and onwards, each side is a separate picture Plate 6 Plate 7 Plate 8 Here I believe they are Tetrarhynchiidae And a large one with amazing colours I decided to keep on original matrix for the main showcase. This one is still not cleaned. @Tidgy's Dad This post is for you!

    Cassiope pizcuetana

    From the album: My collection in progress

    Cassiope pizcuetana Villanova 1859 Location: Teruel, Spain Age: 121 - 113 Mya (Aptian, Early Jurassic) Measurements: 9,6 cm Kingdom: Animalia Phylum: Mollusca Subphylum: Conchifera Class: Gastropoda Subclass: Caenogastropoda Superfamily: Cerithioidea Family: Cassiopidae
  8. The Tyrannosaur Dinosaurs (Tyrannosauroidea) inhabited North America from 152 Million Years ago during the Late Jurassic era up until 66 Million Years ago during the Late Cretaceous era. https://www.app.pan.pl/article/item/app20110141.html However, there is a relatively large geologic gap between the time of the Late Jurassic to the Santonian-Campanian stages of the Cretaceous (when the the oldest known Tyrannosaurid Lythronax (Late Creteaceous, 81.9-81.5 Million Years ago) emerged) in terms of the number of Tyrannosauroidae confirmed in North America. However, this doesn't mean they were completely absent from the Continent. Rather, they remained small to mid sized predators under the shadow of Large Carnosaurs up until the Cenomanian-Turnonian extinction event 93-94 Million years ago, which the tyrannosaurs filled the role of Apex Predator in most terrestrial ecosystems by the Campanian stage of the Cretaceous. The Tyrannosaur geologic gap between the Late Jurassic and Santonian Cretaceous is also not completely empty and several confirmed Tyrannosauroidea are known from this time period in North America. I've created a list of known Tyrannosauroidea species and specimens from the Aptian-Santonian Cretaceous of North America which I would like to share on the fourtm (let me know if there are any examples I'm missing or should add): Unnamed Cloverly Formation Tyrannosauroid (Tyrannosaur – Cloverly Formation, Wyoming, US, North America) (Early Cretaceous, 108 Million Years ago) (Based on Specimen FMNH PR 2750, likely grew up to 1.2 meters (3.9 feet) in length) https://www.tandfonline.com/doi/abs/10.1080/08912963.2010.543952 https://www.researchgate.net/profile/Lindsay- Zanno/publication/229287579_On_the_earliest_record_of_Cretaceous_tyrannosauroids_in_western_North_America_Implications_for_an_Early_Cretaceous_Laurasian_interchange_event/links/0fcfd50089dd8f3955000000/On-the-earliest-record-of-Cretaceous-tyrannosauroids-in-western-North-America-Implications-for-an-Early-Cretaceous-Laurasian-interchange-event.pdf Unnamed Wayan Formation Tyrannosauroid (Tyrannosaur – Wayan Formation, Idaho, US, North America) (Early Late Cretaceous, 100.6-97.8 Million Years ago) (Based on Specimen IMNH 2251/53975, grew up to 1.2 meters (3.9 feet) in length) https://bioone.org/journals/journal-of-paleontology/volume-96/issue-6/jpa.2022.42/A-partial-tyrannosauroid-femur-from-the-mid-Cretaceous-Wayan-Formation/10.1017/jpa.2022.42.full Unnamed Lewisville Formation Tyrannosauroid (Tyrannosaur - Woodbine Group Lewisville Formation, Texas US, North America) (Late Cretaceous (100-95 Million Years ago)) (Based on Specimens DMNH 2013-0701701 and SMU 77218, grew up to 2.7-4.8 meters (8.8-15 feet) in length) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8796713/ Moros intrepidus (Tyrannosaur – Cedar Mountain Formation, Utah, US, North America) (Early Cretaceous (96.4 Million Years ago)) (Grew up to 1.2 meters (3.9 feet) in length) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6385174/ Suskityrannus hazelae (Tyrannosaur – Moreno Hill Formation, New Mexico, US, North America) (Early Cretaceous, 93.5-89.3 Million Years ago) (grew up to 3 meters (9.8 feet) in length) https://www.pure.ed.ac.uk/ws/files/82474043/82473554._Brusatte._AAM.pdf

    Lungfish tooth? Aptian Isle of Wight

    Hi guys found this over the summer from the aptian of the Isle of Wight vectis fm shepards chine member. It looked like the top of a lungfish tooth what do you think? I might just be seeing things.
  10. Found these two partial teeth in my fine material from Carniol France. Aptian - Gargasian One is just the blade the other is just half the tooth. My best guesses are for the half tooth Cretolamna indet. and Protolamna indet. for the blade. Does this make sense or should I keep them as indeterminate shark teeth? scale is mm
  11. Some more find from Carniol my attempt at id based on http://le-coin-a-fossiles.fr/Gargasien.html first Baculites sp. some of my favourite finds Is further id possible?
  12. Still more sorting to do but the belemnites are done. I am struggling to understand the differences between the different Neohiboletes. looking at http://le-coin-a-fossiles.fr/Gargasien.html there are three known species also from the topic below there are diplobelenid phragmacones
  13. As a later summer vacation we decided to do a road trip - Tour de France. France having many interesting destinations and things to do and collecting fossils would be one of them. As we usually don’t plan our trips beyond a few days ahead also the fossil locations were decided on the road. But when reading about Carniol it became clear it was one we had to include. Other non fossil highlights of the trip were Bordeaux, the Pyrenees, Toulouse (great museum of natural history), Lyon and of course Pont du Gard. When finding out about Carniol I did some further reading on how to get there. Apparently the French drive on the very bad (not true) roads to get there like madman (true) at 90 km/h (sometimes true), the cliffs and canyons are very scary (not after the Pyrenees) and parking was also going to be a challenge (it was easy). Carniol is a tiny village and probably the fossil sites are it’s main tourist attraction although calling Carniol touristic is probably very far from reality. Near the village there are two places where the fossil rich clay is exposed and can be easily reached from the road (50-100m walk). The grey clay can be recognised from a distance so it didn’t take us long to get at the site (we only visited the western one but they are supposed to be similar). We were lucky that there was heavy rain in the days before our visit as this exposes the fossils. The downside is that the clay is very sticky and heavy and it forms a plateau under your shoes. As mentioned before the fossils are washed out of the clay and you just need to pick them up. Unfortunately larger fossils are poorly conserved and some nice pieces crumbled after picking them up. But the small fossils are many and diverse. We found lots of what we recognised like Ammonites including heteromorphs, belemnites, gastropods and bivalves like this. As I read that taking some of the clay for washing was of interest (we didn’t prepare for this) we filled an empty 5 liter water container with clay. As we had an appointment for dinner in Lyon and we were satisfied with our finds we left after about two hours. But the rest of the vacation I kept thinking about starting to wash and sort our finds. Back home it became obvious we had some nice finds even before finishing sorting everything. A big tooth my partner picked up but she didn’t recognise as such and she didn’t tell me about (Protosphyraena with a small?). From the clay we brought home, I found a jaw fragment (identified on Reddit as Saurian). Still a lot of material to go through as for now I am just grouping the finds. In due time I hope to get some help with further identification of everything although I will give it a try myself with the information already available here and on other sites.
  14. This jaw fragment was found when washing clay that I brought from Carniol. Cretaceous, Aptian, Gargasian. On Reddit it was identified as Saurian and I was hoping (but doubting) a more accurate identification would be possible. Really happy with this find anyhow. more information about Carniol and my trip there
  15. This tooth was a surface find from Carniol. It was found by my partner and she just put it in her box without telling me recognising for what it was. Nice surprise when sorting / cleaning. On another forum a similar tooth from the same location was identified as Protosphyraena. Cretaseous, Aptian, Gargasian. There are no serrations visible under 10x magnification. At the base the toot is about 5.8mm wide and 4.1mm thick.

    ID help

    Hello I found this piece of sandstone along the Athabasca river just south of Fort McMurray, Alberta, Canada. Since it’s sandstone I’m assuming it came from either the Mcmurray (late barremian or early Aptian) or Grandrapids (Albian) formation although my geology skills are not great. I tried to do some googling on what it could be but I found no results since I couldn’t be specific enough since I don’t really know what I’m doing. Any ideas? I attached an image of the location for fun that I took a while before I found the rock. I found it to the right of the creek thanks
  17. Nice weather here in Texas today. Took a advantage of the warm weather (70's) and went out fossil hunting near the Texas - Oklahoma border nearby Red River. Area is a mixed Antlers and Goodland formation which sort of overlaps each other. Sometimes you will see Antlers Sand formation above the Goodland formation, etc.,. I came across what appears to be a impressive Antlers Sand formation sandstone cliff. These deposits seems to be a fluvial deposits from early Cretaceous period. I could see the river pebble stones embedded in the cliffs. Measured cliff height of about 120 feet. I don't know much about the Antler formation deposits, but from what I read on the Internet dinosaur fossils were found there. Can somebody substantiate that?

    Urchin spine

    Hi, several months ago i found a very tiny and rather flat urchin in a block which had two spines. I managed to disengage the urchin, but it is really too tiny for my camera. The spines are bigger and i wondered to what family of urchin they belong (maybe a cidarid ?) I also join the photos of the urchin that was with them (although i don't know if that would help). @Coco @caterpillar ? The smallest spine : The bigger :
