The Pinecrest Sand Member of the Tamiami Formation is a series of beds which contain an incredible diversity of marine life from the Upper Pliocene ranging from approximately 4.5 to 2.5 million years ago. Primary among the organisms that draw attention to these deposits are the gastropods which are so well preserved that they appear to have just recently washed upon the shore. Although both professional and amateurs have collected from the Sarasota quarries which have mined the mollusk shells for construction for over 50 years, a single monograph has never beeen produced. In addition, I am also picturing gastropods from the Tamiami coral reef facies, the Golden Gate Member which contains some of the same species as the Pinecrest but also many endemics. Although short on description which is essential in peer reviewed scientific publications, I hope this gallery will serve as a guide to those who have trouble in acquiring the few out of date works that have delt with the Pinecrest.
Echinoderms in question do not get preserved apart from isolated fragments and spines which are in turn abundant in some locations. For example, echinoid spines are numerous in Fili Park of Moscow, but their tests are impossible to find. Crinoid stem fragments are large in Callovian/Oxfordian (calyx still unknown) but get tiny in the late Volgian turning almost invisible. Callyxes and complete specimens are yet to be found in the region. Known genera:
Mostly Fili Park, Moscow, Late Jurassic, Middle Volgian (Tithonian), Epivirgatites nikitini zone. Known from this location:
1. Sphenodus shark
2. Palealbula fish
3. Lots of other shark genera (much rarer), marine reptiles (O phthalmosauridae , Colymbosaurinae, Pliosaurus), ratfish, etc.
4. Lots of indeterminate fish vertebrae and occasional bones
A number of my finds from many places.
Everything is self found.
Mostly Ordovician, Carboniferous, and Cretaceous fossils.

I was inspired a while ago by the artistic activity of some of our members, particularly Kane, to have a go at doing some drawings of my own of specimens from my collection. This has turned into an ongoing project, so I will probably be posting things here fairly regularly.
Approximately 70 million years ago, during the Late Campanian Age of the Cretaceous Period, the Earth's oceans were teeming with a diverse array of wildlife. The streams and tributaries where these fossils are found go by many names: New Jersey, United States, and North America. Yet, these designations for the Earth are simply concepts created by humankind; they are arbitrary when held against the eons of nature and life that have preceded humans and that will come after humans. Through fossil collecting, a new appreciation for life on Earth is had. A humbler stance on existence is usually taken by those people who take the time to postulate the intricacies and wonders of nature. These fossils I present to you in this album are a small but beautiful glimpse into one of the many lost worlds that our Earth once was. I hope you may find use for or enjoyment from this album.
Example of an 8.5 hour fossil collecting trip (mixture of surface scanning and gravel sifting):
A snapshot of one drawer from my growing collecting as of (May, 2020):
Artifacts are uncommon, but can be found in many of the streams where fossils are found.
Sharktooth Hill is located in the arid, rolling foothills near Bakersfield, California. It's one of the most productive Miocene bone layers in the world. Fossils of various Sharks..Cosompolitodus Hastalis & Planus, Carcharocles megalodon,Galeocerdo Aduncus,Squalus Occidentalis to name a few...rays,fish and various mammals are some of the items that can be unearthed there as well as a mortality shell layer on the south side of the Kern River...there is even a makeshift cross in the Ant Hill area where someone lost their life digging for the prized sharks teeth...more than one person has been caught in an overburden collapse.It is, and can be dangerous..I was buried before through a freak collapse of the hill side..When starting to dig it's so important to remove the overburden FIRST....sometimes this takes longer than actually digging for teeth...but it will save your life! The layer is composed of the Round Mountain Silt Formation which in turn is part of the Temblor Formation. The bonebed is approximately 15.97 - 13.65 million years old.The age of the bonebed has been extended to 18 m.y.o.range. This can be found in the East Quarry area of the Ernst Property. Active collecting has gone on since the late 1800's. On the south side of the Kern River, Ant Hill, Hang Glider, Sheep Hill, have all been productive sites to collect from..many of the "fire zone teeth" have come from this side of the river. This area though IS PRIVATE PROPERTY so I'd advised contact be made to dig there....Recently on the north side of the Kern River Rob Ernst and Mary Ernst opened up their property to collecting. The dig areas are made up of Slow Curve & the East & West Quarries as well as Snakepit. Sean and Lisa Tohill own the 85 acre Whale Quarry that was once part of the Ernst property. This site is off limits to collecting. The collecting layer is roughly from 6 to 18 inches in depth..it can range from a hard compacted area of gypsum composition to a easy to dig in loose sandy matrix. It wasn't a sudden die off that makes up this bone layer..it was just an area that had remained sediment free for ages and remains accumulated over time.

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.
