PHYLLOCERAS Fossil Ammonite, Aptian Stage, Cretaceous Period | Genuine Moroccan Specimen + COA

PHYLLOCERAS Fossil Ammonite – Aptian Stage, Cretaceous Period, Morocco

This beautifully preserved Phylloceras fossil ammonite represents an extinct genus of cephalopods that thrived during the Aptian stage of the Early Cretaceous, around 125 to 113 million years ago. Found in the fossil-rich strata of Morocco, this specimen offers a fascinating glimpse into ancient marine ecosystems and the evolution of ammonoids.

Fossil Type & Species:

Type: Invertebrate Fossil (Ammonite Shell)

Genus: Phylloceras

Order: Ammonitida

Suborder: Phylloceratina

Family: Phylloceratidae

Geological Age: Aptian Stage, Early Cretaceous (approx. 125–113 million years ago)

Geological & Stratigraphic Details:

Formation: Likely from Cretaceous marine deposits of the Atlas Basin or adjacent units in Morocco

Depositional Environment: Open marine setting with fine sedimentation that supported the fossilisation of delicate cephalopod shells

Biozone: Aptian ammonite-bearing marine strata (specific zonation not formally assigned)

Morphology & Features: This Phylloceras specimen exhibits the key traits of the genus:

Strongly involute, smooth shell with subtle, fine growth lines

Globular to slightly compressed whorls with continuous outer curvature

No ribs or nodes, unlike many Jurassic or Cretaceous ammonites

Intricate suture lines visible on polished or naturally weathered sections

Fossilised in iron-rich limestone or marl, typical of Moroccan preservation, displaying earthy hues of beige, grey, or brown

Notable: Phylloceras is considered one of the most primitive and long-lived ammonite genera, known from the Triassic through the Cretaceous. Its smooth shell and complex sutures are diagnostic and make it both scientifically significant and aesthetically desirable.

Shark News!! Fossil of an ancient shark that swam in the age of dinosaurs solves centuries-long mystery

🦈🦈🦈🦈🦈🦈🦈🦈🦈🦈🦈🦈🦈

[amnhnyc]

It’s Fossil Friday! If you’ve been inside the Museum’s Hall of Vertebrate Origins, you may have noticed this marine reptile hanging overhead. Meet Thalassomedon haringtoni, a long-necked plesiosaur that lived during the Late Cretaceous some 85 million years ago. This behemoth had a relatively small head and many sharp teeth. Its long, flexible neck probably helped in grasping rapidly moving prey. Plesiosaurs, a group related to lizards, lived in the sea. Although they weren’t dinosaurs, they became extinct at the end of the Cretaceous around 65 million years ago, at the same time as the non-avian dinosaurs.

The Museum is open daily from 10 am–5:30 pm! Plan your visit.

🐠 Daily Fish Fact: 🐠

Coelacanths were once known only from fossils and were thought to have gone extinct approximately 65 million years ago. Much to scientists' surprise, the first living coelacanth was discovered in 1938. Numerous characteristics are unique to this fish. Among them is the presence of a "rostral organ" in the snout that is part of the electrosensory system, and an intracranial joint or "hinge" in the skull that allows the anterior portion of the cranium to swing upwards, greatly enlarging the gape of the mouth.

fun fact, did you know that sharks existed before the North Star even formed? they also existed before TREES!

Trident Walliserops fossils.

These fossils come from a pre-historic animalia within the species of trilobite's. Spinose phacopid trilobite's, of the family Acastidae. This is one of other trilobite's which have back spines that exude upwards. This is also one among others like it in particular that stand out as they have their nose-like appendage exuding from its front-side facial carapace.

Gigantic Marine Reptile Fossil Found by 11-Year-Old Girl and Father

A massive jawbone found by a father-daughter fossil-collecting duo on a beach in Somerset along the English coast belonged to a newfound species that’s likely the largest known marine reptile to swim in Earth’s oceans.

Scientists consider the blue whale, which grows up to 110 feet (33.5 meters) long, to be the largest known animal ever to exist on the planet. But it’s possible that the 202 million-year-old reptile, known as an ichthyosaur or “fish lizard,” may have rivaled it in size.

The ichthyosaur’s jawbone, or surangular, was a long, curved bone at the top of the lower jaw just behind the teeth, and it measured more than 6.5 feet (2 meters) long. Researchers believe the creature, named Ichthyotitan severnensis, or “giant fish lizard of the Severn” in Latin, was more than 82 feet (25 meters) long, or the length of two city buses.

Justin and Ruby Reynolds, who live in Braunton, England, recovered the first pieces of the jawbone in May 2020 as they looked for fossils on the beach at Blue Anchor, Somerset. Ruby, 11 at the time, spotted the first chunk of bone, and then she and her dad found additional pieces together.

FIRST-EVER FOOTAGE OF INDONESIAN COELACANTH IN NORTH MALUKU REVEALS NEW INSIGHTS INTO RARE SPECIES

The coelacanth, often dubbed a "living fossil," is one of the most iconic and mysterious marine vertebrates. Long thought extinct until its rediscovery in 1938, only two species are known today—Latimeria chalumnae in the western Indian Ocean, and L. menadoensis in Indonesia. The latter, the Sulawesi coelacanth, lives in deep, difficult-to-access reef habitats and has rarely been observed alive. For the first time, divers using advanced technical diving equipment have filmed a live Indonesian coelacanth in situ, at a depth of over 150 metres in North Maluku, a region where the species had not previously been recorded.

- Localities from whence the Sulawesi Coelacanth, Latimeria menadoensis, has been reported in black stars. White star shows the North Maluku Province, where the first in situ sighting by technical divers was made.

This sighting is more than just a milestone in exploration—it provides critical data on the ecology and distribution of an animal that is evolutionarily unique and highly vulnerable. With few individuals ever seen in the wild, each observation adds valuable insight into how these ancient fish live and where they might still be found. It also underscores the urgency of protecting deep reef habitats that are increasingly at risk from human activities. Understanding and safeguarding the ecosystems that support the coelacanth is essential if we hope to ensure its survival into the future.

Daily Ray Fact:

The Fiddler Ray and their relatives are thought to be the oldest ray group, which explains why they are somewhere between a shark and a ray. It is understood that rays evolved from sharks and so really the Fiddler Ray is a visual demonstration of that change in biology, The earliest known fossil rays are only 150 million years ago and whilst there are very few well preserved fossils available there are whole bodies of ancient guitarfishes which very closely resemble that of modern day Fiddler Rays.
