Pectinodon (meaning "comb-tooth") is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon (though being so small, I'd guess that few people actively search for them). It was a small Troodontid theropod, with teeth that couldn't handle stresses as well as their Dromaeosaurid and Tyrannosaurid cousins (Torices et al. (2018)). This coupled with their small size suggest that Pectinodon was a small/soft prey specialist, preferring the rodent-sized mammals of the ti-

Microfossil tooth & Other Questions about LaFarge Quarry in Harleyville, SC
dr00bie posted a topic in Fossil ID
I had the fortune of collecting at LaFarge quarry back over a decade ago. I didn't find a lot, but took home a 5 gallon bucket of material at the recommendation of another digger to go through for microfossils. Fast forward tp this weekend and I found the bucket of material. It has been drying for this long and is easy to break up. I am just getting started in the material and found a really neat tooth. At first it looked like a Great White tooth to me, but the root doesn't look right. I put under my microscope and found that the tooth appears more conical. The tooth is approximately 3mm in lo -

Orthacanthus (a Xenacathid Chondrichthyan) have squared-off, irregular serrations - distinct from those on say, Dimetrodon. -
From the album: Permian
I commonly see bite marks on many of these fossils. Some like those on this Orthacanthus cusp were likely made by serrations raking across the surface. -

Eagle Ford Hunt With a Fellow FF Member! Loads of Shark Teeth With Some Unexpected Micro Surprises!
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
A couple of weeks ago, @Jackito, his son, and I took a trip out to one of his favorite Eagle Ford sites. For those of you who are familiar with Carter's posts, this was once the famed location of the so-called "giving rock", so the bar was set high for the day. I've come across some of Austin's eagle ford material in the past, but it was always only the leftovers of what had been washed through miles of rushing creek water. This was my first time getting to poke through the source material, so I was eager to see what could be found. The water was low and the temperature mild. I was thankful I- 22 replies

Revueltosaurus was a Pseudosuchian, on the branch of the Archosaurs more closely related to the Crocodilians than the Dinosaurs. Despite the serrated teeth, it is thought to have been herbivorous. -

Lungfish are an ancient group of fish, with swim bladders that evolution co-opted as a kind of "lung," allowing them to breathe air. This may have proven invaluable in a seasonally dry climate in Pangea. -
From the album: Triassic
From the "dawn" of the Dinosaurs, this small tooth represents an early theropod. Unlike the other serrated archosauriform teeth present in the formation, this tooth is ziphodont - thin and labio-lingually compresed - the archetypical tooth form that most theropods adhered to since their beginnings. -
Hello again my good friends. I did a petrographic thin section in a marine consolidated sediment, and i found some elements that seems to be microfossils. It is worth noting that these sediments are in a mandatory-way marine since in all of them are marine bivalves fragments. I also was unsure if put this here or either in the microfossil zone of the forum, leaving it here because it is an ID question. For each I'll leave a views in PPL and XPL. Hopefully someone may be able to recognize them at least broadly, and tell apart them from being forams, big diatoms or even algae. Greetings from Chi

Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the ot

From the album: Chondrichthyan Teeth From The Pennsylvanian Period
Found in the Muncie Creek Phosphatic nodules sadly I do not have the other half, if it is found I will upload it to the comments or post it separately -
From the album: Permian

Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale Found this very small tooth like structure and was wondering if anyone could confirm if it is a tooth or not. Normally I can identify teeth if they are large enough, but this specimen is very small. I have found teeth before in these concretions but much larger such as a possible Symmorium or Glikmanius along with a tooth from a member of Eugeneodontida. Here are some images I edited that might make some details more clea

While fossil hunting last year, I collected some shale from between two lenses of Silurian dolomite in Ohio. I have since cooked it down and searched for microfossils, and all I've found (aside from contaminating insect parts) are what appear to me like marbled fragments of bone and what might be . . . denticles? I'm really not sure and would appreciate any suggestions; please see the attached photos. All fossils are about at most 2 or 3 mm in width. Thanks!
