Fossil seed fern leaves from the Late Carboniferous of northeastern Ohio. A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression. While it is uncommon to find animals preserved as good compression fossils, it is very common to find plants preserved this way. The reason for this is that physical ...
"Nama-type preservation" is an Ediacaran type preservation that presents sandstone castings of fossil creatures in which organisms are preserved in three dimensions, within fine-grained beds that were deposited in single storm or mudflow events: an example is Ausia fenestrata.
Fossil collecting (sometimes, in a non-scientific sense, fossil hunting) is the collection of fossils for scientific study, hobby, or profit. Fossil collecting, as practiced by amateurs, is the predecessor of modern paleontology and many still collect fossils and study fossils as amateurs.
Ginkgo huttonii is known largely by compression fossils of its leaves. Similar to other members of the Ginkgoites, the fossil leaves of G. huttonii are simple, four-lobed, and have dense, radially disposed venation. [3] [2] G. huttonii fossil seeds are frequently found as well as at least a few fossilized male catkins. [4]
It is known from compression fossils found in the Oligocene age Ningming Formation of southern China. Calocedrus huashanensis is known from branches and leaves. southern China †Calocedrus suleticensis: known from fossils found in the Early Oligocene of Probostov (Holy Kluk Hill) in the volcanic complex of the Ceske stredohori Mts., Bohemia.
Fossils have been recovered from every rock type in the Llewellyn but are predominantly found in the siltstone, shale, and coal layers. The compression fossils from the Llewellyn formation are well known for the striking white color on the dark stone. An important location for these fossils is near St. Clair, Pennsylvania.
The fossils within the shale show a remarkable clarity and preservation due to the unique depositional characteristics of the lake and so the Messel pit represents a Konservat-Lagerstätte. The upper stratifications of the lake most certainly supported a variety of organisms, but the bottom was subject to little disturbance by current, spawning ...
A Burgess Shale trilobite showing soft-part preservation. Burgess Shale-type deposits occur either on the continental slope or in a sedimentary basin.They are known in sediments deposited at all water depths during the Precambrian (Riphean stage onwards), with a notable gap in the last 150 million years of the Proterozoic.
