Here is another from the neuse river in NC. Eocene and cretaceous material found there. Scale is mm. How did I do on my guess? Thanks

Allophyllus flexifolia Fossil Leaf SITE LOCATION: Parachute Creek Member-Green River Shale of Garfield County, Colorado TIME PERIOD: Eocene (56 to 33.9 million years ago) Data: Allophylus is a genus within the plant family Sapindaceae. The Sapindaceae are a family of flowering plants in the order Sapindales known as the soapberry family. It contains 138 genera and 1858 accepted species, including maple, ackee, horse chestnut and lychee. The Sapindaceae occur in temperate to tropical regions, many in laurel forest habitat, throughout the world. Many are laticiferous, i.e. they contain latex, a milky sap, and many contain mildly toxic saponins with soap-like qualities in either the foliage and/or the seeds, or roots. The largest genera are Serjania, Paullinia, Acer and Allophylus. The largely temperate genera formerly separated in the families Aceraceae (Acer, Dipteronia) and Hippocastanaceae (Aesculus, Billia, Handeliodendron) were included within a more broadly circumscribed Sapindaceae by the APG. Recent research has confirmed the inclusion of these genera in Sapindaceae.

Eocene Kyiv suite, Lutetian-Bartonian. Personal find. 3 fused scutes: C1,2 - costal scutes, N - neural scute, R- rib. Approximate position of the specimen is shown on the diagramm. -
Periarchus sp. is found in Zullo & Harris (1987) sequence 3 of the Castle Hayne Formation ( Kier, (1980) middle biozone). It is differentiated from Periarchus lyelli only by the placement of the periproct. In P. sp the periproct is below the midpoint between the peristome and the posterior margin of the test. On P. lyelli it is slightly above. Kier (1980), identified this sand dollar as Protoscutella plana; however Osborne, Mooi and Ciampaglio (2013) determined the oral plate structure separate these specimens from Protescutella plana and belonged in the Genus Periarchus.

Collected at the Martin Marietta Castle Hayne Quarry. This is a very common find, though most are limestone or marl encrusted or broken. P. lyelli is found in Zullo & Harris, 1987 sequence 4 of the Castle Hayne (Kier, 1980 middle to late biozone). A very similar species; Periarchus sp. is found in Sequence 3. P. lyelli is most easily identified and differentiated from Protoscutella and Periarchus sp. by the placement of the periproct. The periproct is located slightly above the central point between the peristome and the posterior margin of the test.

Blue Forest Fossil Wood SITE LOCATION: Blue Forest, Eden Valley, Sweetwater Co., Wyoming, USA TIME PERIOD: Eocene (~ 50 million years ago) Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the stem tissue. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried under sediment or volcanic ash and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. Mineral-laden water flowing through the covering material deposits minerals in the plant's cells; as the plant's lignin and cellulose decay, a stone mold forms in its place. The organic matter needs to become petrified before it decomposes completely. The Blue Forest digs have been producing fossil wood for many generations and the locality still continues to give up its treasures. It is located in the west end of Eden Valley approximately 30 miles west of Farson. The fossil wood found in this area is well known for the light blue chalcedony that can be associated with many of the specimens. This chalcedony is frequently found enveloping the fossil wood with botryoidal layers making for very attractive specimens. Those that know say that there is still tremendous collecting potential in the Eden Valley of Wyoming and the Blue Forest digs -- and if a collector spends enough time and energy exploring these deposits his efforts will surely pay off with great finds.

Baltic Amber Gemstone, Fossil, Formicidae, Ant 0.jpg

Baltic Amber, Fossil, Formicidae, Ant Probably Kalingrad area, Russian Federation Eocene epoch, circa 44 million years ago The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It dates from 44 million years ago (during the Eocene epoch). It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014,[3] 400 tonnes in 2015. "Baltic amber" formerly thought to include amber from the Bitterfeld brown coal mines in Saxony (Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited from a more southerly section, in a similar manner as Rovno amber. Other sources of Baltic amber have been listed as coming from Poland and Russia. Because Baltic amber contains about 8% succinic acid, it is also termed succinite. Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago, and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hymenoptera Family: Formicidae -

A tiny tooth of an Abdounia minutissima. Bought from an old collection. The site at which it was collected, the Egem quarry, is now unfortunately closed. (Thanks to @darktheumbreon for finding the family!)

From the album: Some of my best Sheppey fossils
This is a selections of my nautilus collection from the Isle of Sheppey's London clay. The nautilus on Sheppey are often crushed or heavily pyritised but occasionally good quality 3D specimens can turn up.- 1 comment
