Paleodictyon nodosum is a living creature thought to produce a certain form of burrow nearly identical to Paleodictyon fossils. The modern burrows were found around mid-ocean ridge systems in the Pacific and Atlantic Oceans. Although scientists have collected many of the burrows of Paleodictyon nodosum, they have never seen a live one. What a ...
The history of paleontology traces the history of the effort to understand the history of life on Earth by studying the fossil record left behind by living organisms. Since it is concerned with understanding living organisms of the past, paleontology can be considered to be a field of biology, but its historical development has been closely tied to geology and the effort to understand the ...
Palaeozoology, also spelled as Paleozoology (Greek: παλαιόν, palaeon "old" and ζῷον, zoon "animal"), is the branch of paleontology, paleobiology, or zoology dealing with the recovery and identification of multicellular animal remains from geological (or even archeological) contexts, and the use of these fossils in the reconstruction of prehistoric environments and ancient ecosystems.
San Pedro High School discovered a deposit of marine fossils on campus in 2022 and began collaborating with local paleontologists to uncover secrets from the Palos Verdes Peninsula's geological past.
Thus modern invertebrate paleontologists deal largely with fossils of this more strictly defined Animal Kingdom (excepting Phylum Chordata), Phylum Chordata being the exclusive focus of vertebrate paleontology. Protist fossils are then the main focus of micropaleontology, while plant fossils are the chief focus paleobotany.
A fossil preparator handles fossils found in Petrified Forest National Park at the museum's demonstration lab. Visitors are not allowed to take fossils from the park.
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.

The fossil has been identified as a new silesaurid, an extinct group of reptiles. Paleontologists debate whether silesaurids were true dinosaurs or possibly a precursor to the creatures that once ...
