Fig. 12 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 12. Frequency distribution of adult-specimen abundance in 10-specimen size classes for the Elmo entomofauna.

Fig. 11 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 11. Abundance of adult specimens of Elmo entomofauna. Values are plotted from species with fewest known specimens to species with the most known specimens. The species with the greatest numbers of specimens are identified.All labelled taxa are Grylloblattida except for D. tinctum (Psocoptera).

Fig. 10 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 10. Size distributions of the Wellington Formation entomofauna by major taxonomic groups. Size is based on average forewing length in mm.

Fig. 8 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 8. Distribution of size in the Wellington Formation entomofauna. Size is based on average forewing length in mm, plotted from smallest species to largest species. The 13 largest (forewing length>100 mm) and 2 smallest (forewing length <2 mm) species are identified. The two smallest species are both in the family Lophioneuridae. Ten of the largest species belong to the order Protodonata; M. grandis, to Palaeodictyoptera; G. carpenteri, to Caloneurodea; and S. ingens, to Megasecoptera.

Fig. 9 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 9. Frequency distribution in 5-mm size classes of average forewing lengths for the Wellington Formation entomofauna.

Fig. 7 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 7. Species diversity of the Wellington Formation entomofauna by Order (Suborder for the Grylloblattida). Orders are placed in three groups, Apterygota, Pterygota: Palaeoptera, and Pterygota: Neoptera, and are arranged in decreasing order of number of species. Bars show the number of species in each taxon unique to Elmo, unique to Midco and common to both. The nearly 200 species represent some 21 orders, 53 families and 106 genera.

Fig. 5 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 5. Proportion of Wellington Formation entomofauna Neoptera and Palaeoptera subgroups unique to or shared between the Elmo and Midco localities, illustrating that the greater percentage of unique fauna at Elmo arises from the Neoptera. This reflects the fact that no review of the Neoptera from Midco has yet been published.

Fig. 6 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 6. Comparison of the distribution of the Elmo Permian and World extant entomofaunas by major groups: Apterygota, Palaeoptera, Polyneoptera, Paraneoptera, and Holometabola.

Fig. 4 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 4. (A) Gilbert O. Raasch (1903–1999) discovered the Midco fossil insect beds and documented the stratigraphy of the Oklahoma Wellington Formation in his PhD Thesis (Raasch 1946) (photo courtesy University of Wisconsin-Madison); (B) Paul Tasch of Wichita State University studied the palaeolimnology of the Wellington Formation in Kansas and Oklahoma and discovered additional Wellington Formation fossil insect localities in the late 1950's and early 1960's (photo courtesy of Wichita State University Department of Special Collections, Wichita, Kansas).

Fig. 3 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 3. The settlement of Elmo, Kansas, as it appeared in the early 1900's. The fossil beds, located a few miles southeast, were named after the town. (Photo courtesy of the Wichita State University Libraries Department of Special Collections.)

Fig. 1 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA

Fig. 1. Location and extent of the North American mid-continent Lower Permian Wellington Formation insect fossil deposits. The formation runs north to south some 270 km along eight counties, with major sites at the northern (Elmo, Kansas) and southern (Midco, Oklahoma) extremities.

University of Oklahoma CopterSonde Files from LAPSE-RATE

This dataset contains quality-controlled thermodynamic (temperature, pressure, humidity) and kinematic (wind speed and direction) measurements from the University of Oklahoma Center for Autonomous Sensing and Sampling team during the LAPSE-RATE campaign from 14--19 July 2018. These files are from the fleet of 3 individual CopterSonde rotary-wing UAS used during the campaign. Differences between them have been accounted for through calibration. See README_v1.txt for more information.

Data for "To heal or not to heal? Part I: The effect of pore fluid pressure on the frictional healing behavior of Oklahoma lithologies"

This dataset includes the original data files for each experiment in csv format, the mat version with an additional friction column, the hold picks, the velocity step picks, and the RSFitting results. They have the following names: <ul> <li>UC####.csv</li> <li>UC####.mat</li> <li>UC##_hold_picks.mat</li> <li>UC##_healing_picks.mat</li> <li>UC##_VS_RSFit.mat</li> </ul> The CSV and mat files include the on-sample shear displacement data labeled LVDT1 and LVDT2 and the on-sample radial displacement data labeled LVDT3. All data files except for the RSFit include an OG_Index column which is consistent across files for each experiment, such that it provides a unique indicator for each datapoint. Note that all experiment numbers are available in the main text, except for UC0094, which is shown in the supplement text S6.
