Three-Dimensional Modeling of Tidal Delta Reservoirs Based on Sedimentary Dynamics Simulations

open access: yesApplied Sciences
To increase the reliability of three-dimensional (3D) geological models in areas characterized by sparse well data and poor seismic quality, a sedimentary dynamics simulation was conducted on the J7 tidal delta sedimentary reservoir in the Y gas field ...

Visualization of three dimensional earth fissures in geological structure

open access: yes, 2015
This paper proposes a new method for visualizing the earth fissures of geological structure in three dimensional (3-D) domains on the basis of the seismic data and features information of earth fissures. The seismic data were interpreted for obtaining

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

A three-dimensional geological model of the Paleozoic bedrock of southern Ontario

open access: yes, 2021
An updated regional three-dimensional (3-D) lithostratigraphic model of the Paleozoic bedrock of southern Ontario has been produced using Leapfrog© Works software, improving a model completed in 2019. The model encompasses the entire Phanerozoic succession of southcentral and southwestern Ontario consisting of approximately 1500 metres of Paleozoic ...

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).

True three-dimensional trishear: A kinematic model for strike-slip and oblique-slip deformation [PDF]

open access: yes, 2004
Most structural/kinematic models are inherently two-dimensional; even several recent three-dimensional models are "pseudo-three-dimensional" in that they consist of a series of parallel two-dimensional cross sections.

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation

open access: yesThe Anatomical Record, EarlyView.
Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...
