Could someone tell me what these are (first photo)? They were found on late eocene sediments near Vic, Catalonia, Spain. The only other fossil around were corals/sponges (would also appreciate if someone could confirm) like the one in the second photo attached so these stood out.

Did Allosaurus survive up to the earliest Cretaceous
Joseph Fossil posted a topic in Questions & Answers
The Theropod Dinosaurs of the genus Allosaurus since their discovery in 1877 are perhaps one the most recognizable theropods of the whole Jurassic period (201.4 ± 0.2-145.0 Million Years ago) despite emerging only in the late Kimmeridgian stage of the Jurassic period. Growing up to 9.7 meters (32 feet) in length fully grown, Allosaurus (also known as the Lions of Jurassic) were the apex predators of most of the terrestrial ecosystems they inhabited. The only theropods from these time that were higher in the food chain were some European non-Allosauroid Theropods and other members of Allosauroidea including the much rarer Epanterias (validity debated, possibly grew fully grown up to 12 meters (40 feet) in length) and Saurophaganax (validity confirmed, fully grown reached 10.5 meters (34 feet) in length). Digital Reconstruction of an adult Allosaurus sp. By artist Frederic Wierum Image Source: https://fredthedinosaurman.artstation.com/projects/Qg0WB The Allosauroids eventually gave rise to some of the largest theropod dinosaurs known in the fossil record currently including the closely related South American genus Giganotosaurus from the Cenomanian stage of the Late Cretaceous period (99.6-95 Million Years ago) in what is now Argentina (which fully grown grew up to 12-13 meters (39-43 feet) in length). But Allosaurus itself has largely been considered to have lived only in the latest stages in Jurassic period (155-145 Million Years ago). I have found some records that might challenge this assumption!!! Digital Reconstruction of an adult Allosaurus sp.

The leaf (5cm long) cames from Fumanya Sud site, in Spain. It's about 72-70 million years old. In geological context it is found in the Tremp Formation, specifically in the group called "Unitat Gris", also know as Gray Garumnian. Does anyone have any idea what species it's or what group it belongs to? Thanks. If you want more photos or information for a better identification, ask!

Hi guys , I hope you can help me in identifying this rock .I found it in a small dry river in Catalunya. It is covered by small quartz or calcite crystals I think. I am not sure if it is a fossil, maybe a coral fossil? Thank you 🙏
-
Ok, so I found these two pieces on eocene deposits in Catalonia. These are probably just extremely big coral, but dreaming is free ... Do you think they could be bones? Possibly ribs of a marine mammal?

This are two carboniferous fossils from Arlanza, Spain. The first one is a Pecopteris and the second one is a tree trunk if I am not mistaken. Do you have a different opinion or have a more specific ID? The Pecopteris The tree trunk

I'm a bit new to this, so this might be a stupid question but here we go. I found this on marine Eocene deposits in Catalonia, Spain. Could this part of a crab? Or maybe an echinoderm?

This summer a friend brought me this rock from the town of Pomer (Zaragoza). The age of the rocks in the area is Cambrian and I think it could be some kind of arthropod, I don't know... It was found at an altitude of 1300m. Can someone help me?

In 2018 I made a trip to the Jurassic Museum of Asturias (MUJA) and visited the footprint site of Playa de la Griega. The site has footprints of sauropods and allosaur theropods from 154 million years ago. In the same deposit I found a rock with what at first glance seems to be a footprint, even on some finger you can see what I think is a toe claw. Being so small, I thought it would be from a baby Allosaurus. The setting of the site is coastal, at that time the area was a beach. I doubt that the fossil could be from any bivalve but I am not an expert. Can someone who knows about footprints help me please? If you need more photos, do not hesitate to ask! (The size of the footprint is 3cm long x 2,5 cm) Thanks.

Some time ago I met a fossiliferous area that is located in the transition from the Silurian to the Devonian in Catalonia, Spain. The site is the Santa Creu d'Olorda Quarry. The rocks belongs to the Facies Griotte. I found these specimens in the area and I don't know what they could be. I've read reports that crinoids and some trilobite have been found in the area, but it doesn't look like either. Can any one help me please?

Hello everyone, first time here... Last week on Burgos, Spain, I found my first fossil. It seems an Echinoidea buy it is very damaged. I have read that there is a lot of types of Echinoidea, can anyone let me know which class specifically is this one? and how old is it? Does it have something inside? It seems to have kind of bright or transparent parts around the fossil (red circle). Sorry for my unknowledge. Thanks in advance for your time!

I decided to visit a very astonishing area in Navarre, in the North of Spain. This site is a semi-desertic area of 41 845 hectares with 45 kilometers from the North to the South and 24 kilometers from the West to the East. It's formation began 70 Million of years ago, when the isle that was Iberia joined Europe. The sea waters were trapped during formation of the Pyrenees and the Catalan and Iberican Mountains, forming a dead sea that was alimented by rivers. Those rivers brought a thickness of sediments that reached until 6 kilometers. 10 Million of Years ago, the depression opened by the Catalan coast and the salted waters flowed away in the Mediterranea leaving the place to the Ebre and its affluents. Fossils from the Miocene have been found there. They show a lacustrine environnent : birds, turtles, mammals, foraminifers, amphibians, ostracods, algae, gastropods. In 199-2000, it was classified by the UNESCO because of its unique biosphere and landscapes. Some movies and series have been filmed there

A new spinosaurid dinosaur species from the Early Cretaceous of Cinctorres (Spain)
PFOOLEY posted a topic in Fossil News
A new spinosaurid dinosaur species from the Early Cretaceous of Cinctorres (Spain) Abstract A new spinosaurid genus and species is described based on the right maxilla and five caudal vertebrae of a single specimen from the Arcillas de Morella Formation (Early Cretaceous) at the locality of Cinctorres (Castellón, Spain). Protathlitis cinctorrensis gen. et sp. nov. is diagnosed by one autapomorphic feature as well as by a unique combination of characters. The autapomorphy includes a subcircular depression in the anterior corner of the antorbital fossa in the maxilla. The new Iberian species is recovered as a basal baryonychine. The recognition of Protathlitis cinctorrensis gen. et sp. nov. as the first baryonychine dinosaur species identified from the Arcillas de Morella Formation (late Barremian) from the same time as Vallibonavenatrix cani, the first spinosaurine dinosaur from the same formation in the Morella subbasin (Maestrat Basin, eastern Spain), indicates that the Iberian Peninsula was home to a highly diverse assemblage of medium-to-large bodied spinosaurid dinosaurs. It seems that spinosaurids appeared during the Early Cretaceous in Laurasia, with the two subfamilies occupying the western part of Europe during this period. Later, during the Barremian–Aptian, they migrated to Africa and Asia, where they would diversify. In Europe, baryonychines were dominant, while in Africa, spinosaurines were most abundant. s41598-023-33418-2.pdf- 3 replies

Hello, I have bought this gastropod in a flea market in spain, and I was wondering if it's possible to ID it. Due to it's large size and location my first option is Natica leviathan (now Ampullina leviathan). I don't know if I am right or some body has a different opinion?

Hello, I'd love to know your opinion about these reptilian vertebrae coming from the lower santonian of northern Spain. Fisrt photo is view from above and second from beneath I've made some guesses about this piece, and I hope some of you could give me your opinion about them. Here come muy guesses: -Taken that it comes from clear ancient marine strata, its general morfphology and its Santonian age, I think it probably is a mosasaur vertebrae. The problem is that there hasn' been any mosasaur reports in these places, basically because vertebrate remains are really rare and fragmented -Supposing that the mosasaur ID is correct, the next logical step would be trying to discover which kind of vertebrae it is. In the second photo, its beneath view, you can see a big spherical gap (it is highlighted in picture 3), and from it, I'veguessed this vertebra cannot be a dorsal, nor a caudal, because the chevrons there are conected to the vertebrae by a symetrical paired haemal arches (so not a big notch in the center) I have related this spherical gap with the small chevron like bones which kind of appear beneath some mosasaur cervicals. To show clearer what a I refering to, picture 4 is a higlighted image of this bone I am refering to So, so far, I've guessed I'm dealing with a mosasaur cervical vertebra I would love to know what are your opinions about these guesses and, also, if there's a detalied mosasaur vertebrae monograph I could go for Thanks in advance!!!! Cheers

A Spanish association announced today a find of a new Baryonychine. Dario Estraviz Lopez said "its going to be a new Iberian Spinosaurid almost as complete as the holotype of Baryonyx." Very cool and might provide more insights into these dinosaurs.
