Late Cretaceous chalk in North America
The Amateur Paleontologist posted a topic in General Fossil Discussion
Hey everyone I know I've been lately rather inactive on TFF; I was held back by fieldwork and other reasons (though do expect some posts about the fieldwork next weekend ). But anyway, onto what I came to talk about... Would anyone know of some good exposures of Late Cretaceous chalk in Canada or USA? I'm thinking specifically about Campanian chalk or, even better, Maastrichtian chalk.. It would be great if the exposed chalk is very fossiliferous, of course. Thanks for any help! -Christian -
Hello, I went on a walk a few days ago to the local chalk pit and of course couldn't resist spending a few minutes scouting for fossils. This is one of two specimens that I found, the other being a shell fragment. At first I thought the pattern might be formed by ice but I wasn't convinced and kept searching, managing to recover two other small pieces. My suspicion of it not being ice related was confirmed when at the bottom of the slope I found the more complete counter slab, with a layer of ice still covering part of the fossil. Needless to say this made for cold hands on the wal

2020 - a year in review - part two - my best finds of the year - Echinoids
elcoincoin posted a topic in Fossil Hunting Trips
Initially, this summer we had planned to spend a week in the eastern part of France, but despite there was no official lockdown at the time and since the area had been badly strike by the pandemy, we decided to postpone that trip. Instead we organised a 4 days trip along the cliffs of Normandy. The first day we aimed to "Cap de La Hève " near Le Havre. The rocks are from the cenomanian We didnt find that much, but all in all we still managed to grab a few nice echinoids and brachiopods. Some samples of the very small Discoides subuculus (1 cm for the biggest) :- 7 replies

Hello, I found this inside a loose chalk boulder on the Eastbourne shore. Based on the colour of the chalk it appeared to be from the upper cliff levels, perhaps cretaceous levels.

Hi, sorry i know nothing about fossils but found this curious round egg-shaped thing inside chalk near Beachy Head, Eastbourne, UK. The nearby clay had some similar round dark brown items inside. Any ideas what this is?

Hi everyone! I haven’t been on here, or posted In FOREVER. These rocks were in a creek bed in Devine TX. When I found a pocket There was a soft sometimes liquidy sometimes dryer Chock like substance. There was three colors. Red, orange, and almost yellow. Is this what the cave drawings were made with?!?! I don’t have good pictures of the chalk stuff right now bat can get them later.

Hi We found these and picked them up on the basis they dont look anything like the flints in this ground. So not what they might be, any info would be appreciated like the other finds these were in a shallow valley in east suffolk under 1.5m of flinty sand and on top of or in the top layer of heavy grey clay with some chalk and slint in it.

Hi all, I was hoping for some help with this. Is it a fossil? It’s quite worn so I’m not expecting a detailed ID but some suggestions would be fantastic. I found it at Hunstanton which is chalk or Cretaceous age. I’ve also found lots of brachiopods and echinoids at this locality.

We found this in a pond we have dug on the site of an old pond at the juncture between the clay infill and the undisturbed clay under the old pond. depth 1.75m. Heavy clay with flint and chalk in it location Suffolk on boulder clay in the bottom of a very shallow valley I thought it was man made as it was so detailed but my my son and friend think it is a fossil so here are the pictures against a ruler showing inches and centimeters

Using vinegar/acetic acid to reveal small teeth in chalk
The Amateur Paleontologist posted a topic in Fossil Preparation
Hey everyone, hope you're all doing well! From what I've read, small shark/fish teeth can be occasionally encountered by dissolving samples of chalk/limestone in acid. I read Jeppsson et al's 1999 paper on using buffered acetic acid to extract phosphatic fossils (in my case shark teeth), but the method outlined is not that simple and requires access to certain laboratory equipment I don't really have access to right at the moment... All I have is some cheap white vinegar, and some trays and tins I've got some samples of chalk from the Late Cretaceous of Møns Klint, a f -
I live in Thanet, England - classic White Cliffs country, chalky and flinty. Found this amongst the gravel in my driveway, so may be local, might not. Centimetre rule, so about 3 cm by 2 cm by 2cm.

Need help in identifying problematic fish bone
The Amateur Paleontologist posted a topic in Fossil ID
Hey everyone Hope you're all doing well! While looking through unprepped/untouched blocks of chalk from last year's fieldwork session in the Late Cretaceous of Møns Klint (Denmark), I found one block that showed a little trace of fish bone. I scraped a bit around it with some dental tools, and managed to reveal the whole fossil. And I'm having quite some trouble identifying it... Could anyone help me? I've included pics and details of the specimen below. Pics: Note especially the 'ridges' in the upper half of the fossil Full detai -
Fossil hunting in the shed like many of us - I thought I'd lost this nice globular rhynchonellid in a house move years ago. From the top Campanian/bottom Maastrichtian Chalk of Norfolk, UK. I think it's Cretirhynchia sp.

Found this rock in Wisconsin US near Lake Michigan. At first I thought it was a collection of bones but looking closer I just don't know.

Since we have to avoid crowded places due to the current situation , it was a good excuse to go out fossil hunting in the open. We went to the beach at the Cenomanian chalk cliffs, and we were in for a big surprise. The day before we got there, there was a big spring tide, the high water levels cleaned up all of the scree piles from the winter landfalls. Lots of fossils were emerging from the lose boulders on the beach, sometimes even just laying around waiting to be picked up. We even got a few new species for our collection: Natalie found a nice Turillites scheuzerianus a

Hi I. New here. I’ve been collecting for about 5 months in central Texas. I found something that I’ve not come across before. It looks like something from a palm like plant but it could be an animal... it’s 3.4inches long . Thank You.

I'd be grateful for advice on this item found high on the South Downs in West Sussex, England.. The Downs are chalk, the item found Flint. I would like to know if this is a fracture pattern or a fossil bivalve - or something else altogether. The surface is corrugated.

Hey Everyone. I'm headed over to the Tuscaloosa area specifically to hunt some of the chalk banks along the Tombigbee. Instead of going on a wild goose chase, I was wondering if anyone knew of some spots around there where they had luck with shark and mosasaur teeth. Preferably, I am looking for spots that are not considered private property or hunting grounds. Thanks for the input!

Hi to all, I've been trying to find a positive id for this one for some time now, my guess is that it could be a partial conical shell with remains of the animal still inside it. The inner 'shell' and contents are pyrited (iron), found in Wiltshire,England in a predomately chalk and flint with a very thin topsoil area, iron pyrite nodules are very common in this location. Than you Tony

Preparations for my 3rd Møns Klint Fossil Excavation
The Amateur Paleontologist posted a topic in Fossil Hunting Trips
Hey everyone - It's Christian. For the past few months, I was inactive on TFF as I had a lot of schoolwork.. But now, I've got a lot more time on my hands - which means that I can get back to all things fossil related This of course includes making preparations for my 3rd Møns Klint Fossil Excavation (MKFE - the fieldwork aspect of my Møns Klint Fossil Research Program). I'll be going for 2 weeks, in mid-August - I'm really excited! As I said in a post from a few months ago, the collection policy of this MKFE is essentially the same as last time's (cephalopod, crustacean, echi- 10 replies

I'm used to find ammonites and invertebrates, but this time I took home piece of chalk from the beach with a bone inside. I have totaly no Idea of what kind of bone this is or even from what kind of creature. I am still prepping the piece, but those are already the 1st few pictures. hopefully someone got more info on this: Cenomanian from cap-blanc-nez France ( marine chalk deposits)

I was at the chalk cliffs at Seaford in April this year hunting for echinoids. However, I only found time to clean and prep these fossils this week, using a safety pin, a brush and water (Very low-tech, I know!). UKfossils.co.uk states the rocks here are Cretaceous, 89-86 million years old. I found a fist-sized chunk of chalk that yielded two enchinoderm plates (picture 4) and a very small, unknown fossil. Pictures 1-3 show the unknown fossil. 1 division on the ruler is 1mm. It is perfectly spherical, with a diameter of about 4mm and has raised dimples covering its surface. There are
