JBkansas posted a topic in Fossil News
Perucetus colossus, new whale fossil (39mya) from Peru, estimated to have weighed upto 340 tons. https://www.washingtonpost.com/climate-environment/2023/08/02/largest-animal-whale-p-colossus/ Article (paywalled): https://www.nature.com/articles/s41586-023-06381-1 -
Perucetus colossus, Peruvian basilosaurid fossil, possibly larger than blue whale
rew replied to JBkansas's topic in Fossil News
My own collecting is mostly Paleozoic, but there are plenty of interesting fossils that come later. Like this early whale. https://www.cbc.ca/news/science/perucetus-whale-fossil-heavy-1.6925284 -
I’m starting to work on the Carcharhinus and related shark displays. I’ve got three teeth from the Pisco Formation, Sacaco location that I can’t quite nail down as far as ID. I know they could end up being Carcharhinus sp but I thought I’d give an ID post a chance. I’m not really confident in my ability to ID the gray sharks. The first two look like they might be C. obscurus to me but I know there would be other possibilities. They are both right around 13mm on the slant so not very large. The first one is in better shape, the second is pretty worn. The third tooth is actua

Carcharodon carcharias (Neonate) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru Right Upper Lateral A small tooth from a young-of-the-year great white (~ 1.5 m / 5 ft total length). Teeth of these very young individuals are narrower than adult teeth, and possess lateral "cusplets" - features that aid in their piscivorous (fish-dominated) diet. -

Carcharodon carcharias (Young Juvenile) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru 2nd? Left Upper Anterior A small tooth from a very young great white (< 2 m / 7 ft total length). Teeth of these very young individuals are narrower than adult teeth, and can possess lateral "cusplets" - features that aid in their piscivorous (fish-dominated) diet. -

Carcharodon carcharias (Neonate) Pisco Formation, Departamento de Arequipa, Sitio Sacaco, Peru 3rd Right Upper (Intermediate) A small tooth from a newborn great white shark (~ 1.5 m / 5 ft total length). This is a rare intermediate tooth which is mesially-slanted, and reduced in size relative to adjacent teeth. The smaller size of the 3rd upper anterior is an adaptation unique to the dentitions of Lamniforms, thought to concentrate the bite force in the first two upper anteriors. -
Identification Teeth of Carcharodon carcharias may be identified by triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Teeth of neonatal individuals (newborn/young of the year) possess small lateral "cusplets," with a deep "V" profile made by the root lobes, and are more narrow than adult teeth1. This narrow tooth form with cusplets is suited for the great white's piscivorous (fish-dominated) diet at a young age. Comments This is an exceptional upper right lateral tooth from a newborn or

Cool bichrome great white tooth from the Early Pliocene of Southern Peru. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -

Lower tooth from an early great white (Early Pliocene). Juvenile teeth are narrower than those of adults, more suited to a piscivorous (fish-eating) diet. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -

Nice color on this early great white shark tooth (Early Pliocene). This one comes from the desert of southern Peru, where a long period of sand blasting has smoothed this tooth to a near-polish, all but erasing the serrations. Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit by the BHI. -
Identification Teeth of Carcharodon carcharias may be identified by erect, triangular crowns with no nutrient groove in the root, no lingual dental band ("bourlette"), and irregular triangular serrations on the edges. Comments This tooth is Early Pliocene in age, which is about as old as great white shark fossils get. Fossils are now illegal to export from Peru. This tooth was collected by the BHI during a series of expeditions to Peru 1985-1990 under a government permit.

Found this tooth in ica, Peru. Anyone know what it’s from? From quick research it appears to be a shark, but what kind?
-
Can anyone identify this? Is it a fossil? All three pictures are of the same rock from different angles.

Great whites didn't start out "great." As young, small animals, they had narrower teeth suited for grasping slippery fish. As they age, the teeth broaden as their diet transitions to marine mammals. This small tooth measures ~ 1" on the slant and comes from the Early Pliocene of the Pisco formation in southern Peru. This is about as old as great white teeth get, they evolved from C. hubbelli near the start of the Pliocene (~ 5.3 Ma). Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit. As ethical collectors, please do -

These white sharks come from the deserts of Chile (left) and Peru (right). -

Some rare colors on this tooth! While it looks like Bone Valley, this great white actually comes from southern Peru (Pisco formation, Early Pliocene). This is about as old as GW teeth get - the modern species evolved from C. hubbelli around the Early Pliocene (~ 5 million years ago). Fossils are now illegal to export from Peru, this one was collected prior to 1990 under a Peruvian government permit. As ethical collectors, please do your due diligence to verify any Peruvian fossils you're interested in were exported prior to the ban. I respect any country's decision to protect their natural -

Basilosaurus' skull found in Ocucaje Desert, Peru - Possible new species
Oxytropidoceras posted a topic in Fossil News
Ferocious 'Ocucaje Predator' was a sea serpent-like mammal with knives for teeth Brandon Specktor, Live Science, March 19, 2022 In Peru, skull of ‘marine monster’ points to fearsome ancient predator Scientists think the ancient mammal was a Basilosaurus, part of the aquatic cetacean family, whose contemporary descendents include whales, dolphins and porpoises.

One of the newer teeth in my Megalodon tooth collection. I have been collecting Megalodon Teeth for some months. now. The tooth is around 4 8/16 inches big and has some restoration on the root. I love the colors and serrations! Show me your South American megalodon teeth!

On a recent trip in Perú, near the coastal town San Juan de Marcona, I saw several middle to late Pleistocene marine terraces. In this one, fossil fragile clams and stout scallops are well-preserved, separately packed in thin strata. I think they are Anomia peruviana and Argopecten purpuratus. clamsscallops Also found one unidentified gastropod Photo shows clam stratum just below scallop stratum.
