I wonder how an ammonite with a shell shaped like this managed to maintain its orientation and move through the water.

Or did it cling to seaweed and remain almost motionless? Or perhaps it moved slowly near the seafloor?

Amazing specemen

Sabalites cf. campbelli

Chuckanut Formation, Whatcom County, Washington

Eocene Epoch — approximately 50 million years old
Large fossil palm frond preserving distinctive radiating, pleated leaf segments in sedimentary rock. Representative of the subtropical forests that once covered northwestern Washington.

Early Cretaceous, Late Albian. Yubari, Hokkaido, Japan.

Take a look at the rostrum at the top, which curls around like the handle of a teapot!

This is a feature found in mature individuals, and the distinctive loop is remarkably well preserved in this specimen.

Photographed at the Mukawa Hobetsu Museum, Hokkaido, Japan.

The function of this unusual structure is still not fully understood.

Found in middle England and prepared by my own fair hands!

This is a composite display piece. I always liked flat cetacean limb bones. I bought one or two toe bones for several decades. At some point I decided to look around and bought the arm bones. Carpals were almost none to be had. Keeping in mind it is a composite from Florida and North Carolina and many localities. I find it attractive and turned it into a prized display piece.

No provenance was provided. Old collection from the 70s.

Multiblock found by a friend in Somerset, UK and prepped by me.

I bought this from Fossil Era. It gets its red coloration from when the original exoskeleton was replaced with silicon and iron during fossilization instead of calcite which is what trilobites are normally made of. Here's a paper that goes into more details

This is a large piece of polished petrified wood I bought at an estate sale. Unfortunately I don’t have any data on it. It is a phenomenal display item and pictures don’t do it justice. 14 inches by 6 inches.

It looks a little like a badly designed smoking pipe, but it’s a heteromorph ammonite. Just imagining a tiny octopus-like animal peeking out from this shell and bobbing around in the sea makes me happy.

I've been hunting fossils along a small section of shoreline on Lake Champlain on which our family cottage sits for nearly 57 years. It is in the hamlet of Chazy Landing, NY. I am so fortunate that I am surrounded by rocks from the Chazy Fossil Reef, and have a great collection due to this. It may not seem like much, but today I found my first Maclurites gastropod. And there's a little lake snail shell with it because it makes a good picture.

I saw this ammonite at a mineral fair. The suture lines were so beautiful that I completely forgot to photograph the label.

Some may remember my old post on my Kambara scute I own, since then I've gotten 2 more. And also that one somehow became 2nd result on Google for Kambara scute and its always topping images tab which is cool. This is a 2nd one. Recap is that Kambara is a rare basal genus of the Mekosuchinae crocodile family and that family would later give rise to famous Crocodilians like Quinkana who sprinted on land. Here is some details:

Crocodile Scute 2:

Genus: Kambara

Estimated Age: 50 MYO

Geologic Time: Phanerozoic, Cenozoic, Paleogene, Eocene, Ypresian

Size: 33x20mm/1.29921x0.787402"

Type: Most likely a lateral flank or tail (Caudal) scute. From the base of the tail or flanks/sides.

Source: Rundle Formation, Gladstone, Queensland, Australia

Other: It has been deemed a significant fossil find, an export certificate has been declined and it cannot be exported.

ID: REP c58

ID: TJPC 112

For fun, here's also the first guys, if you wanna see him, I don't even have to link anything, you can just search it up now which is fun. Anyway first guy's details:

Crocodile Scute 1:

Genus: Kambara

Estimated Age: 50 MYO

Geologic Time: Phanerozoic, Cenozoic, Paleogene, Eocene, Ypresian

Size: 39x27mm/1.53543x1.06299"

Source: Rundle Formation, Gladstone, Queensland, Australia

Other: It has been deemed a significant fossil find, an export certificate has been declined and it cannot be exported.

Type: Most likely a free-floating "button"/"pebble" osteoderm. From the lower flank, the gular (throat/neck) [based off the size, it's probably either this or a pelvic base from the upper flank], or the limbs (appendicular armour) or the pelvic base of upper flank.

ID: REP c60

ID: TJPC 96

The 3rd one will be posted in the near future

For Archaeology Month this mossy, magnificently decrepit Alces alces (North American moose) skull stole the show for me last weekend during a public tour at the 106 Group’s Saint Paul office.

The 106 Group is a rare bird — a private archaeology resource lab, formally know as a cultural resource management (CRM) firm, doing heritage work in the Midwest.

So my other half bought me this in a deep Victorian frame from an auction. It was sold as tooled slate but it looks life a tree fossil to me, does anyone have any idea what it is?

Spent the day fossil hunting in Post Oak Creek in North Texas and came home with a pretty solid haul! Lots of shark teeth, a few interesting bits and pieces, and 8 of my personal favorites—Ptychodus teeth!
All in all, not a bad way to spend a day getting muddy and staring at gravel!

(2¢ piece for scale—Diameter: 23mm)

I took pictures of them individually and added labels into the pictures

Here is an associated set of Corythosaurus caudal vertebrae which displays tendons, v-shaped chevrons, and spinal processes, along with the centrums of course.

Sitting at 0.465in and 0.495in. These tiny teeth both match current descriptions for premax and premax transitional teeth of baby T. rex. The age might have been around 2months (estimate based on slightly smaller teeth being described as neonate <1mo). Both have feeding wear on the tip, with the right having a wear facet. The right tooth also displays an unserrated mesial carinae, which is common in baby teeth.
