The north-striking, 19 km-long Cliff fault passes 1.5 km west of the Sevilleta National Wildlife Refuge headquarters. My study uses stratigraphic relationships to interpret tectonic activity of the Cliff fault during the early Pleistocene. Previous work had suggested the latest movements occurred during the late and middle Pleistocene (Machette, 1978), but early Pleistocene activity remained uncertain. It is necessary to use Santa Fe Group stratigraphy because potential early Pleistocene activity on the Cliff fault antedates preserved geomorphic surfaces or fault scarps. The Cliff fault is the easternmost of a trio of Quaternary normal faults in the southwestern Albuquerque Basin, the other two being the east-down Loma Pelada and Loma Blanca faults to the west. Because these faults have been mapped as extending southward into the northern Socorro Basin, interpreting their long-term displacement behavior is important in understanding how strain is transferred between the Albuquerque and Socorro Basins. Long-term (10 6 -10 7 yr) paleoseismic records of the fault trio can also be used to evaluate if fault activity has migrated towards the center of the basin. The Cliff fault offsets strata of the Sierra Ladrones Formation, a Pliocene-early Pleistocene deposit composed mainly of sand with lesser gravel and silt-clay. The studied sediment lies stratigraphically above a sample locality of a 3 Ma tooth fossil. My field research illustrates several lithofacies in the Sierra Ladrones formation, including two different types of channel fills, floodplain deposits, hyper-concentrated or debris flow deposits, and possible colluvium and slope wash deposits. The two different types of channel fills are: (1) sandstone-dominated and trough cross-stratified, with southerly paleoflow and abundant chert clasts,

I first went public with contrarian views on uranium during the depth of the global financial crisis in the late fall and early winter of 2008-2009. In addition to speaking about the commodity in interviews, I initiated coverage of two Athabasca explorers and both were eventually acquired by major mining companies. One produced more than a double (Mercenary Musing, November 24, 2008) and the other a triple (Mercenary Musing, January 14, 2009) respectively for my portfolio and subscribers who chose to follow my lead.

Metoposaurs (Temnospondyli: Metoposauridae) were large, ubiquitous amphibians of the Late Triassic. They were important members of the Upper Triassic Chinle Group fauna of New Mexico and are found in these strata across the state. One of the most important metoposaur bonebeds in the world occurs in the Adamanian (upper Carnian) Garita Creek Formation near Lamy, NM, where the fossils of hundreds of individuals were hydraulically concentrated on a Late Triassic floodplain. In nearly all metoposaur populations, worldwide, many skull features show shape change throughout ontogenetic growth (allometry). Some workers have believed these allometric growth trajectories to be of taxonomic value. Here, using the largest populations available (for maximum statistical sample size), we investigate the taxonomic utility of these shape changes. Skull allometry in three populations of the metoposaur Koskinonodon perfectum (Lamy, NM; Rotten Hill, TX; Popo Agie Formation of WY) was compared to establish intra-specific variation. Then, three populations representing different genera ( Dutuitosaurus ouazzoui from northern Africa; Koskinonodon perfectum from western North America; Metoposaurus diagnosticus from eastern Europe) were compared to show variation at the generic level. Anteroposterior movement of the orbits and relative skull width at three positions (snout tip at the anterior nares, basal snout at the anterior orbits, greatest width across the quadratojugals) with respect to midline length throughout ontogeny were determined. Relative orbit position moved anteriorly in D. ouazzoui and K. perfectum (Rotten Hill), posteriorly in K. perfectum (Lamy) and K. perfectum (WY), and remained approximately fixed in M. diagnosticus . Skull width allometries were of mixed values, but with rare exceptions, the snout grew wider with respect to length throughout ontogeny, whereas the posterior skull became relatively narrower. Thus, the skulls of juveniles were somewhat triangular, and they grew to be more parallel-sided with a wider, blunter snout in adults. Comparison of the calculated allometric constants from the various populations yielded a surprising result: intra-specific variation in growth patterns was as great as or greater than inter-generic variation. The three K. perfectum populations, including the Lamy metoposaurs, were not significantly more similar to each other than they were to different genera. The salient point of this preliminary work is that allometric skull growth trajectories in metoposaurs probably have little or no taxonomic value, and metoposaur taxa should probably not be erected based solely on variations in growth patterns.
