I've found a few decent sea urchins myself. Crinoids and blastoids are however quite rare in my area and the stars and other families of this order are even harder to come by, particularly when you tend, like myself, to restrict the majority of your collection to samples which you've found yourself in the field. This is why this section of my collection remains quite modest. I've just lately begun to trade a bit and some good friends have given me some nice samples, so things are improving.
An album containing some of my (@Max-fossils) photos from the Zandmotor (NL)!
The Zandmotor is a big beach on the coast of the Netherlands. It is known for its variety of fossils: abundant fossil seashells (mostly clams and cockles); fish material; sometimes bird material; the occasional shark teeth (some from the very early Holocene, others from the Eocene); and of course mammal material (mammoth, woolly rhino, cave lion, hyena, horse, etc.)! The bone material is either from the middle Pleistocene (600'000 years ago), from the late Pleistocene (40'000 years ago) or from the very early Holocene (9'000 years ago); about 90% are from the late Pleistocene. Most of the seashells are from the middle Pleistocene, more precisely the Eemian stage (120'000 years ago); however, seashells from other ages are found too.
Other (non-fossil) finds include: modern seashells and artifacts.
These fossils come from various channel deposits found in Wyoming's Lance formation which is contemporary in age and fauna to the more famous Hell Creek formation of MT, SD & ND. These fossils were all found on private property outside of Newcastle, WY.
My main interest is fossil fish, but here in this album, you will only find invertebrates:
Fossils from Solnhofen, Messel, Holzmaden, Liaoning, Bundenbach, Green River, Linton, Mazon Creek, Monte Bolca, Fiume Marecchia...
This album includes Carboniferous plant fossils my wife and I collected at St. Clair before the site was closed. I'm sorting the specimens now. We have specimens of Alethopteris, Annularia, Asterophyllides, Cordaites, Neuropteris (and Cyclopteris), Pecopteris, Sphenopteris, Stigmaria (tree roots), Lepidophylloides, Lepidodendron, Calamites, and more.
In the 6 years that we've been collecting fossils, paleobiological discoveries have clarified many of the form and species genera originally used to identify and group coal swamp fossils. In the 19th and 20th century, many Pennsylvanian plant fossils were identified by shape or configuration. Consequently, many fossils were mistakenly grouped together, and some differently shaped parts of the same frond were given different species names. For example, the round Neuropteris leaves often found at the base of a tongue shaped Neuropteris leaf are often identified as cyclopteris which is a "form genus" originally used to designate a round fern leaf with veins.
We are learning more about fossil seeds, also. Trigonocarpus was the general catch-all name given to most Carboniferous seeds but now we are learning which seeds were associated with which trees and fossil leaves, most notably seeds that grew on the Medullosa family of trees.
Like most fossil collectors, we are still attempting to understand the ecology of fossil plants and trees, how they evolved, and the role they played in evolution in general. We believe that preserving fossils and displaying them are better than leaving them in the ground to decay.
My main interest is fossil fish, but you will also find some other vertebrates like amphibians, mammals, reptiles and birds here in this album:
Fossils from Solnhofen, Messel, Holzmaden, Liaoning, Bergisch Gladbach, Green River, Linton, Mazon Creek, Monte Bolca, Fiume Marecchia.....and other places around the world.
