Abstract Coleoid cephalopods are characterized by internalization of their shell, and divided into the ten‐armed Decabrachia (squids cuttlefish) eight‐armed Vampyropoda (octopuses vampire squid). They have a rich fossil record predominantly limited biomineralized skeletal elements they possess: arm hooks, statoliths, mouthparts (the buccal mass) internal shell (gladius or pen), although exquisitely preserved soft tissue coleoids known from several Lagerstätten worldwide. Recent studies shown...
One of the best records late Paleozoic ecosystems, Mazon Creek Lagerstätte is world famous for its striking flora and fauna preserved within siderite concretions. Distinct from other Carboniferous concretionary Lagerstätten because remarkable fidelity soft tissues pigments that are frequently preserved, has seen a revival in investigations during last 10 years using modern palaeontological techniques. However, many these build upon literature incorrectly interprets palaeoenvironment separate...
Abstract Replacement of soft tissues by calcium phosphate can yield spectacular fossils. However, in the fossil record, phosphatization internal organs is highly selective; some organs, such as muscles, stomachs, and intestines, appear to preferentially phosphatize while other seldom phosphatize. The reasons for this are unclear but one hypothesis that, during decay, create distinct chemical microenvironments only fall below critical pH threshold mineralization occur (i.e. carbonic acid...
Concretions are an interesting mode of preservation that can occasionally yield fossils with soft tissues. To properly interpret these fossils, understanding their fossilization is required. Probabilistic models useful tools to identify variations between different Konservat-Lagerstätten separated spatially and temporally. However, the application probabilistic modeling has been limited Early Paleozoic preserved in shales. In this paper, patterns three concretionary...

Hundreds video games, spanning a huge variety genres and platforms, use extinct animals and/or palaeontological themes as basis for their gameplay. Because this, many players, especially children, spend long periods time engaging with being immersed in concepts themes. may be first medium implicit or tangential science communication they engage with, regards to palaeontology.

The fossils of the Lebanese Upper Cretaceous Lagerstätten, especially articulated fish, are world renowned. Famous for their soft tissue preservation and highly sought after by fossil collectors, provide key information concerning evolution several major extant extinct groups Mesozoic organisms including cephalopods, crustaceans, hagfish, sharks, marine reptiles pterosaurs. In fact, from Lebanon so exceptional that historical documentation describing them extends back to Roman Empire....
The southeastern part of the Tejon Quadrangle, California, is interest to economic geologists for light its history may throw upon that near-by-oil-producing and potentially productive regions. rocks are both crystalline sedimentary; sediments, Tertiary Quaternary age, aggregate more than 30,000 feet in thickness. Faulting dominant structural feature. area divided into three units by Clearwater Palomas Canyon faults. fault has had a complex history, vertical horizontal movements having...
Dredge samples of a coarse sediment taken from depth 150 fathoms water off the southeast end Santa Catalina Island, California, exhibit characteristics that suggest to be beach origin. The conclusion is reached island has subsided approximately 600 feet in post-Middle Miocene time, and possibly post-Pleistocene time.
Abstract Data compilations expand the scope of research; however, data citation practice lags behind advances in use. It remains uncommon for users to credit producers professionally meaningful ways. In paleontology, databases like Paleobiology Database (PBDB) enable assessment patterns and processes spanning millions years, up global scale. The status quo creates an imbalance wherein publications drawing from PBDB receive significantly more citations (median: 4.3 ± 3.5 citations/year) than...
Because of physiology coleoids, their fossils preserve soft-tissue-remains more often than other cephalopods. Sometimes, the phosphatized soft-tissues, particularly parts muscular mantle, display dark circular patterns. Here, we showcase that these patterns, here documented for fossil coleoids from Jurassic Germany and Cretaceous Lebanon, superficially resemble chromatophores (which enable living to alter coloration). We examined chemically analyzed structures in specimens, describe them,...
Controversy regarding the origin of furrows or trails occurring on surface Racetrack Playa in Death Valley National Monument led to search for evidence same phenomenon other playas. Such was found Little Bonnie Claire Nye County, Nevada, first form a few nearly obliterated trails, and later numerous fresh following protracted rain wind storm. The author is opinion that are made wet slippery clay playa by rocks propelled wind.
ABSTRACT The positions of submarine epicenters seismic shocks occurring during a twelve and one-quarter year period were plotted on bathymetric chart the area off southern California. data show: (1) that sea floor is active seismically, (2) activity topography are related. It appears major topographic features tectonic origin forces which brought them about still active.
Abstract Landscape architects are challenged to create places that promote human interaction, involvement, and experience. While there is a growing body of literature providing performance-driven design guidelines, dearth direction for those wanting landscapes more engaging landscape experiences. This paper addresses this gap by posing theoretical relationship between an individual's perception cognition, the use elements their qualities in site design. The posits Csikszentmihalyi's flow...

Abstract The Jarrow assemblage is a Lagerstätte of Pennsylvanian tetrapods and fish preserved in the Leinster Coalfield, Ireland. Fossils from this site have an interesting taphonomy that not observed other coal swamp assemblages. tetrapod bone material has undergone alteration eventual coalification, causing specimens to become poorly defined surrounding matrix. Bone at traditionally been linked early diagenesis. A multi‐analytical approach, combining x‐ray scanning electron microscopy,...
