Fossil Friday: Copper Replacement

This is petrified wood but it has not been replaced by silica like it usually would be. It has been carbonized and replaced by copper minerals. It comes from  the Nacimiento Mining District, Sandoval County, New Mexico, USA. (Incidentally, I used to live in this county when I was a child. Beautiful deserts out there).

The copper minerals came about because the environment of deposition created oxygen-reduction in a river system (lots of rotting wood and buried plant material). This caused mineral precipitation when copper-bearing water flowed through the permeable sands.

Copper minerals found in the wood at this site include malachite,

azurite,

and chrysocolla.

It is rare for fossils to be replaced with non-silica or calcite minerals but every now and then the conditions are just right to allow that to happen.

Now you know about one more way to fossilize something. Tune in Monday to learn how to find copper in the wild. Fossilize you later!

Triceratops Dinosaur Fossilised Tooth Fossil Genuine Specimen

Triceratops, which literally means 'three-horned face’, is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago (mya) in what is now North America. The Triceratops had a sharp hard beak and rows and rows of teeth, some having as many as 800 teeth, allowing them to slice and crush all sorts of vegetation. Despite their fearsome appearance, they didn’t kill other dinosaurs for meat, but they likely would have defended themselves well from predators using their 3 horns which featured on one of the largest heads of any land dinosaur discovered.

Fossil promicroceras jurassic ammonite, marston magna, somerset, uk

Scale cube=1cm: Full sizing please see photo

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity

Specimen: Promicroceras

Age: Marston Magna, Somerset, UK

Location: Gloucestershire, UK

Fossil Promicroceras specimens from Marston Magna, Somerset, UK, offer a fascinating glimpse into the ancient marine environments that existed during the Early Jurassic period, approximately 200 to 175 million years ago. Promicroceras is a genus of ammonites, a group of extinct cephalopods with coiled shells, and their fossils are commonly found in the Jurassic rocks of the UK.

The geological formations in Marston Magna have proven to be a rich source of well-preserved ammonite fossils, including those of Promicroceras. These fossils are typically discovered in sedimentary rocks, providing a snapshot of the marine life and environmental conditions that prevailed in the region during the Early Jurassic.

Promicroceras ammonites are characterized by their small size and elegantly coiled shells. The species often has distinctive ribbing on its shell, creating a visually striking appearance. The fossils found in Marston Magna showcase the intricate details of these shells, including the ornamentation and sutures, which are the complex patterns where the internal chambers of the shell intersect.

The abundance and diversity of Promicroceras fossils in Marston Magna make them valuable for both scientific study and as prized additions to fossil collections. Their small size and intricate features make them popular among fossil enthusiasts, and their well-preserved nature provides researchers with insights into the taxonomy, ecology, and evolution of ammonites during the Early Jurassic.

Ammonites, including Promicroceras, are important index fossils, aiding in the dating and correlation of geological strata. The rapid evolution and widespread distribution of ammonites make them valuable markers for understanding the relative ages of rock formations.

Studying Promicroceras fossils from Marston Magna contributes to our broader understanding of the ancient seas and the diverse marine life that inhabited them millions of years ago. These fossils serve as tangible links to the past, allowing us to explore the dynamic history of life on Earth and the evolution of marine ecosystems during the Early Jurassic period.

Fossil hunting visit 2

I got a lot of few new fossils for todays post. Found another location with lot of stones & rubble. With the ok from the owner of his pile/ surrounding field area to search.

It was an fun time to search for rocks this time. Mostly broken upper and top fragments of flint urchins, nice finds to compare with others.

These are quiet big chunks of echinoid.

Two of them, after washing in my hand are mostly intact ones.

It‘s a shame all years thats pieces like this got lost and destroyed from the shipping for fundamental use or industrial constructions or street underground.

Oh there is no blood, it is the wet red marking of the inner flint layer.

Some fossils and rocks from Glen Harbor, Michigan.

A local winemaker in Gobelsburg, Austria, unearthed a mammoth discovery, literally: 300 mammoth bones dating back 30,000 to 40,000 years! Learn about this remarkable find and its implications.

I was at Giełda Minerałów i Skamieniałości (Minerals and Fossils Market) and I've got some stuff (fossils only of course) I will show at home later!

Felt my soul respawn when I saw this agatized dinosaur bone from Australia
