Hi- I found this today at Lake Benbrook, Tarrant County Texas. I was looking for newly exposed large ammonoids. I believe that it is possibly from the Woodbine formation because I also found some nice Gryphaea- looks like maybe Parasmilia but it also looks like has a shell- 3.5 inches x 1 inch. Your expert help appreciated- Thanks-

Hey, a question I have always wanted to ask is about dinosaur relatives, more specifically what do we mean when we refer to two dinosaurs as cousins ? Do we mean that a kind of dinosaur(for example baryonyx ) lived in an environment but at one point a group got separated by land and this group got to live in another part of the world so that group resulted in adapting to another environment and becoming a different dinosaur (for example spinosaurus ) or do we mean that a dinosaur is an ancestor of another dinosaur (again for example baryonyx evolved into spinosaurus)? This may seem like a really basic question to ask but I haven't really been able to find an answer so if someone answered it would be great.

I watched a show on PBS last night, "When Whales Walked: Journeys in Deep Time." I just happened to notice it on the guide about 45 minutes before it was on. It is actually about more than the evolution of whales, the group having four-footed Early Eocene ancestors. There is a long segment roughly twenty minutes long each on crocodilians, birds, whales, and elephants. I thought it was a good show overall with interviews of researchers I know from their technical articles ( Hans-Dieter Sues, Philip Gingerich, Emmanel Gheerbrant, Christian de Muizon). However, each segment was also a little light on content for the topic and one was especially unclear. The one on birds made it appear that Deinonychus was an ancestor of later birds. They should have showed a chart showing when it lived in the Cretaceous with Archaeopteryx and the Liaoning birds millions of years before. There was a quick view of a family tree that seemed to illustrate that but it went by in a second or two. The segment on whales showed a lot of footage of modern whales and some great background on the "first whale," Pakicetus, but it didn't show any of the whales described in the past twenty years. It just mentioned that there had been recent discoveries. I thought there should have been at least a quick look at Ambulocetus and a few of the increasingly more marine-adapted forms that lived before Basilosaurus. They pretty much jumped from Pakicetus to Basilosaurus to the divergence of toothed and baleen whales. I think they could have spent the two hours just on the whales just as the title of the show led me to believe. I liked the segment on elephants because just as I was expecting the show to skip the earliest known members of the group, they go to Morocco and then talk to Emmanuel Gheerbrant who described Phosphatherium, the first probiscidean, which is known from the same early Eocene phosphate layer as a lot of the shark teeth we see at shows are from. Other extinct forms were descussed as well. Here's a link that takes to an online notice and website: https://www.pbs.org/show/when-whales-walked-journeys-deep-time/ Jess

Need some help identifying layers of fossil sediment along a steep cliff side, having a hard time distinguishing time zones. Thank you!

A warm hello to all. I’m afraid I’m a very unknowledable beginner, but making every effort to learn and hoping for some friendly help. I have just discovered I live very close to the Jurassic Coastline of Yorkshire in the Uk! Never before did I realise you can find such a gigantuous array of delights here. It was only a few weeks ago this took my interest and I wanted to find an ammonite of my very own. Then it gets addictive and now I want to know more. I have found a selection of rocks with bits and bobs in them, ammonites, and possibly an Ichthyosaur vertebrae. I am here to ask lots of questions about extraction to identification to preserving. Any links and book suggestions would be most welcome. Thanks so much to all!

I found these two embedded in the same bit of shale on the yorkshire coastline near Kettleness. Im a complete beginner so sorry if they are just rocks. they are both a similar size, 6cm by 4cm (LxW)

Hi everyone. This is my first request for an ID, I'm a complete newbie with limited knowledge but very eager to learn. This might be nothing, but I thought it was strange. Found loose on a Yorkshire beach (UK) unsure whether it was washed up by the sea or came away in a cliff fall. Area known for ammonites/Mesazoic/Jurassic finds. Measures approx 9cm in length, 18 cm circumference.

I believe these are parts from a crab I found in NJ, from what I see I think the large one is from the shoulder or bicep from a crab, is it possible to identify anything else about the animal?this side is fairly flat with the bottom edge protruding out.this side is round but in pretty bad condition.side view of the piece.

Tried my hand at two different styles of drawing an icthyosaur. Don't exactly remember the species I was going for but I remember that it and the fish are both from the Jurassic. this one is a bit more realistic. and this is a cartoony representation.

Howdy from the frontier country of New Mexico! I'm Tammy. I stumbled upon this forum while trying to categorize a very large collection of interesting fossil specimens collected in the mid to southwest of New Mexico, by our daughter Carol (an avid fossil collector). During her last visit we separated some of the largest specimens, revering some more than others, discussing the cosmos and the earliest life forms on planet Earth. We recalled that Carol collected rocks as souvenirs from vacations. On a vacation to Minnesota, Carol collected a '(flat) rock'; it was a decade later when she realized it was actually a prehistoric tool! I'm positive that's what started it all! I hope you can forgive our lack of 'technical' terms and a few run-on sentences now and then, as we attempt to analyze and understand this collection. I'm off to read and learn! Sincerest gratitude, Tammy

Dipping my toes in 'bama's Cretaceous waters.
MeargleSchmeargl posted a topic in Fossil Hunting Trips
Armed with information courtesy of @FossilDAWG , I've headed to Montgomery, Alabama to get my first taste of Cretaceous fauna from 85-80 MYA (Santonian and Campanian stages). After booking a hotel in close proximity to the creek and (restlessly) sleeping the night away, We ate breakfast, got our boots on and eagerly drove to the site with the help of a GPS. When we arrived, the GPS signal was showing us miles off from where we actually were, so Google was shelved and Papa and I started the flurry of pictures. As per description, the entrance to the site itself was kind of jagged, made of huge concrete slabs left there from a time long forgotten. After we got down this man-made hill, I took a moment to take in the sight, the outcrop plainly in view: We slowly sloshed through the creek, being careful not to slip on rocks or step into deeper-than-you-think holes in the stream bed. Once we got to the outcrop on the far side, we got right to looking. Barely even 5 steps in, I instantly recognized the blade of a shark tooth that was sticking out of the sand. It has little root on it, though I can tell that it is probably a sand tiger. It is the only one I've found, so far. Venturing further in, we started finding Oysters. Lots of them. It wasn't long before we found what was apparently the main bed they came from: To sum it up; Bivalves. Bivalves everywhere. You almost can't walk there without stepping on pieces of them they're so abundant. With everything there, it didn't take very long to get a decent haul, with pieces of ammonites, two echinoids and a lone gastropod being added to the seemingly limitless supply of bivalves. I was quite tempted to get back in the creek and have another go at it, but Papa balked, citing the heat which was in the 90's, and since he was the driver he had all the decision-making power. I came away with 4 specific favourites, the gastropod, the 2 echies, and one particularly complete valve (the name of which eludes me, as I am by no means an expert in bivalves). The right-most echie's top side is covered in River crud, though as I found it practically in the water. Cleaning tips, anyone? Do keep posted, as I will make 3 return trips, when temps aren't in the 90's.

Looking for current lithostratigraphy Mesozoic of Madagascar
paleoflor posted a topic in Questions & Answers
L.S., As you can probably tell from the title of this topic, I am looking for information on the lithostratigraphy of the Mesozoic of Madagascar. Specifically, I would like to have an up-to-date overview of the terrestrial formations that occur on the island. Can anyone recommend me a good resource, say a recent review paper? Based on bits and bobs I read in more recent papers, it appears that the stratigraphy book I have now (Besairie and Collignon 1971, Géologie de Madagascar: Las terrains sédimentaires) is somewhat outdated... Thanks for your help! Tim -
I wanted to share some of my projects with all of you. A hobby and side business of mine is creating dinosaur sculptures. I do all different kinds of things aside from dinos too, but to keep it relevant, we’ll stick to the mesozoic Featured in my profile picture is my raptor created from scrap metal used to construct railings. I named him Bambi (ironically not a Bambiraptor). Probably more like Deinonychus, he’s a pretty big chicken, but you let me know what you think. As of now he’s my favorite creation, hence why he’s featured in my profile pic. Still trying to figure out the paint job. I wish he’d stop scaring all the birds and deer away...

Hello everyone I have here a specimen and can’t figure out if it’s just a plain ol’rock but I think it might not be a rock at all. This specimen weighs almost 5lbs it’s original location was found in Carrizo Springs Texas at a drilling rig location. Some helpful info and opinions about what this specimen could be would really be great -Thanks y’all!

Hello all, In juli I go to the south of France for 2-3 weeks. We go every year to a different place. Now I want to ask if there are good hunting spots over there that are free accessible? I would prefer to find some vertebra fossils but I know that might be hard. Inverts are also fine. Anyone here that can help with tips or locations? I never found fossils in the south before but I know they are there. We don't go to the West/South coast because there are too many tourists over there. Thanks in advance. Greetings

I've been told this could be something, fossil or inorganic. It was found in the same Mesozoic area as previous finds in the Big Sky, MT area. Just looking for some input pertaining to what it could be whether it's a rock or something more......

Not sure if this is petrified wood or a concretion due to the dark center on one side. I could use some clarification and input.

Heteromorph is my most recent sculpture with a paleontological theme. This is the rear view of the sculpture showing the shell spines. -
From the album: james herrmann
In this right side view of the sculpture I would like to show the green marble base. I chose this mottled green marble as a continuation of the kelp forest theme. I envision this ammonite pulling its way along the waving fronts of a kelp forest as it forages for small crustaceans. Kelp forests are contrasts of warm, bright beams of light and deep shadow. The marble is mottled in various shades of green much like looking down onto the kelp forest's waving fronds.- 2 comments

From the album: james herrmann
In this view I again wanted to show the cantilevered structure of the sculpture and the subtle color differences in the patination of the shell vs the body of the ammonite. -
From the album: james herrmann
In this front left view I wanted to highlight the waving of the kelp. The challenge was to strongly support the heteromorph while still making the sculpture feel like there was movement and a lightness to the work. -
From the album: james herrmann
This left side view of the sculpture shows the attachment of the ammonite to the kelp, actually there is a lot of bronze in the mass of tentacles. From the base to the top of the sculpture is approximately 40 inches. -
From the album: james herrmann
I like the complex repeating nature of the spines in this view of the sculpture. I am supporting the mass of the bronze ammonite with the bronze kelp leaves welded into a trellis-like pattern to carry the weight down to the base. -
The coin in the photos is a 50 cent piece. Found in Western Colorado. Really unsure of type. Piece is very dense, similar to river rock. The thickness of the bone at joint is 2 3/4".
