چکیده
More than 20,000 siderite concretions from the Mazon Creek area of northern Illinois, United States are housed in paleobotanical collections Field Museum. A large proportion contain fossil plants Middle Pennsylvanian age that often have excellent three-dimensional morphology and sometimes anatomical detail. Approximately eighty plant taxa been recognized Lagerstätte, but few studied detail, some cases systematic affinities these fossils need reevaluation. The (3D) preservation makes them ideal candidates for study using x-ray micro-computed tomography (μCT), here we apply techniques to more accurately reconstruct specimens Tetraphyllostrobus Gao et Zodrow Crossotheca Zeiller. mineralogical composition was elemental maps Raman spectroscopy. In-situ spores were with differential interference contrast, Airyscan confocal super-resolution microscopy, scanning electron which reveal different features degrees clarity. Our analyses show μCT can provide detail on structure fossils, nature associated mineralization enhancing obscuring critical information. Results guidance selecting prioritizing preserved future research.

متن کاملComparison of transportation and centering ability using RECIPROC and iRace: A cone-beam computed tomography study
BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...

The objective of this study was to evaluate the pituitary gland dimensions due to age and weight using computed tomography (CT) in dogs and cats. The CT images of pituitary gland were assessed in 11 client-owned dogs (six males and five females; age range, 1 to 9 years) and 15 client-owned cats (eight males and seven females; age range, 1 to 14 years) with no evidence of pituitary diseases. The...
