AAH this is such a hard question haha

Thanks so much for asking @insectsinthestars ! I felt like this required some photos!

I truly do not think I have a favorite, I tried to pick one but I could not. I love them all so much. Here are a few that mean the most to me though!

This blob of Bryozoans! This one is special to me because it is a chunk of just pure Bryozoans, it is actually super light and REALLY delicate. Every time I set it down, it sheds some particles. The fact that this survived the elements for potentially hundreds of millions of years makes my heart tighten up.

These are also the largest branches I have found, by far! (Bryozoa are tiny tiny animals that live in colonies, similar to coral)

Of course, I have to include my ONE trilobite haha. Yeah, that was a good day. I kinda love that it is just his little booty, hehe. Maybe one day I will work up the courage to attempt to chisel the rest of it out, I just reallllly do not wanna damage it. But yea.. man, do i cherish it

And I would honestly feel bad not including any Brachiopods, since they make up 80% of my fossils. But again, I really can’t choose a favorite:( I have a lot and I love them all. So these one’s are from the very beginning of my fossil hunting days (2019) and I can still remember finding them and crying in the woods :’)

So apparently it is ‘Fossil Friday’:) I like this term!

I cracked open that one from my last post and was rewarded with my favorite genus of Brachiopod, ✨ Leptaena ✨!! so beautiful..

Also I cracked open this mush

I managed to weasel this lady out!!

I am honestly not too sure what I am looking at in the 2nd photo, I am 93% sure this is half of a Brachiopod, so I am guessing those are the innards, so I am also guessing that that circle is the pedical, maybe? It is just so large?. I have never found one with the inside visible like this. And I just can not find any references I need .. anybody know?

Also another Leptaena was also in there

And an adorable Bryozoan sheet that makes me crave honey:)

And here is a better photo of the chisel project I was working on the other day! I am a little stuck on this one, I really do not want to damage the Crinoid, it seems so fragile..

current CIP (chisel in progress) :D

Enrolled Phacops Trilobite Fossil | Devonian | Morocco | Authentic 5-10mm Specimen

Discover an exquisite and genuine specimen of an Enrolled Phacops Trilobite, dating back to the Devonian period, sourced directly from the renowned fossil-rich beds of Morocco. This fascinating fossil represents a small but distinct segment of Earth’s biological and geological history, perfectly sized at 5-10mm and ideal for collectors, educators, or fossil enthusiasts.

Phacops trilobites are particularly notable for their well-preserved compound eyes and ability to enroll as a defensive mechanism. The enrolled form adds to both the rarity and appeal of this piece. Please refer to the scale cube (1cm) and photos for accurate sizing and detail; the image shows an example of the specimen you will receive.

Each fossil is carefully selected to ensure quality and authenticity. All of our Fossils are 100% Genuine Specimens and come with a Certificate of Authenticity.

This Phacops trilobite belongs to the family Phacopidae, within the order Phacopida, and the superfamily Phacopoidea. While a more detailed taxonomic classification (such as biozone or formal discoverer) cannot be confirmed with certainty for this specific lot, Phacops trilobites are commonly associated with Devonian marine deposits, particularly within the Emsian to Givetian stages. The depositional environment was a shallow, warm, marine shelf conducive to the preservation of such detailed fossils.

Geisonoceras Orthoceras Fossil Orthocone | Middle Devonian Eifelian Morocco | Genuine Specimen with COA

Add a captivating piece of prehistoric marine life to your fossil collection with this genuine Geisonoceras (formerly grouped under Orthoceras) fossil orthocone from the Middle Devonian period, specifically the Eifelian stage, unearthed in the famous fossil-rich region near Alnif, Erfoud, Morocco. This exceptional specimen displays the long, chambered shell structure characteristic of ancient nautiloid cephalopods.

Fossil Type: Orthocone Cephalopod

Genus: Geisonoceras (previously Orthoceras)

Geological Period: Middle Devonian (~393 to 388 million years ago)

Geological Stage: Eifelian

Location: Alnif, near Erfoud, Anti-Atlas Mountains, Morocco

Scale Rule: Squares/Cube = 1cm (Please see photo for full sizing)

Specimen: Actual fossil shown in the photo is what you will receive

Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity

Geological and Paleontological Context

Geisonoceras is a genus of extinct nautiloid cephalopods from the Order Orthocerida, known for its long, straight (orthoconic) shell composed of internal chambers. These marine invertebrates lived in open marine settings and played an important role in the Paleozoic marine ecosystem.

Phylum: Mollusca

Class: Cephalopoda

Order: Orthocerida

Family: Geisonoceratidae

Superfamily: Orthocerataceae

Geological Stage: Eifelian (Middle Devonian)

Depositional Environment: Shallow marine shelf; fossil typically preserved in grey to black limestone indicative of low-energy sedimentation in a carbonate platform environment

Morphological Features: Long, slender conical shell (orthocone) with visible internal septa and a siphuncle running longitudinally through the chambers; polished specimens reveal exquisite detail of these features

Notable: Geisonoceras is distinguished from similar genera by the structure of its siphuncle and the spacing of septa. These orthocones are often used as biostratigraphic markers in Devonian carbonates

Biozone: Not specifically assigned without exact stratigraphic data

Identifier: Initially described and differentiated from Orthoceras by 19th-century paleontologists refining nautiloid classification

Why This Fossil Stands Out

This stunning Geisonoceras specimen has been carefully chosen and polished to enhance its natural features. It provides a detailed view of the phragmocone (chambered shell), ideal for both educational purposes and display. Sourced from one of the most prolific fossil sites in North Africa, it exemplifies the diversity and preservation quality of Devonian marine fossils.

Orthoceras vagans Fossil Orthocone | Devonian Morocco Hammar Laghdad | Genuine Specimen with COA

Enhance your fossil collection with this authentic and beautifully preserved Orthoceras vagans fossil orthocone, originating from the Devonian period and discovered in the renowned Hammar Laghdad site, near Erfoud, Morocco. This striking fossil represents an extinct genus of straight-shelled cephalopods, known for their long, conical shells and fascinating internal chamber structures.

Fossil Type: Orthocone Cephalopod

Species: Orthoceras vagans

Geological Period: Devonian (~419 to 359 million years ago)

Location: Hammar Laghdad, Anti-Atlas Mountains, Morocco

Scale Rule: Squares/Cube = 1cm (See photo for full sizing details)

Specimen: Actual item pictured is the specimen you will receive

Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity

Geological and Paleontological Information

Orthoceras vagans is an extinct nautiloid cephalopod from the Order Orthocerida, which flourished in the world's oceans during the Paleozoic Era. These marine invertebrates had long, straight shells composed of calcite and were divided internally into chambers. The animal inhabited the last chamber, with the earlier chambers used for buoyancy control via a siphuncle running through the center.

Phylum: Mollusca

Class: Cephalopoda

Order: Orthocerida

Family: Orthoceratidae

Superfamily: Orthocerataceae

Geological Stage: Likely from the Emsian to Givetian stages of the Middle Devonian (stratigraphic confirmation not provided)

Depositional Environment: Marine platform setting, part of a shallow epicontinental sea that covered the region; fossil-bearing layers consist mostly of black limestone and mudstone

Morphological Features: Long, straight conical shell (orthocone) with internal chambers; central siphuncle visible in some specimens; external ornamentation may include growth lines and faint ribbing

Notable: Hammar Laghdad is internationally known for its abundant and well-preserved Devonian marine fossils, especially orthocones and trilobites

Biozone: No specific biozone designation without exact stratigraphic layer

Identifier: While Orthoceras was first described in the 18th century, species-level classification such as vagans typically references work by subsequent 19th and early 20th-century paleontologists

Why This Specimen Stands Out

This particular Orthoceras vagans specimen has been carefully selected for its quality and visibility of features. The polished surface highlights the internal chambering and linear form that make orthocones so iconic. Whether you're a seasoned collector or new to paleontology, this piece is both educational and decorative.
