As part of a continuing investigation of trace fossils from the lower-most, Albian Sarten Member of the Mojado Formation, we report the first description of Curvolithus simplex at Cerro de Cristo Rey, Sunland Park, New Mexico. C.simplex is a horizontal, three-lobed trace interpreted as a repichnia. Other traces in this ichnoassemblage that are commonly associated with the Cruziana ichnofacies include Thalassinoides, Arthrophycus, Planolities, scratch marks (and others not yet reported). Our Curvolithus specimensare preserved exclusively in convex epirelief on iron-stained, massive sandstones, interbedded with thin grey shales. At this location the lower contact of the Sarten Member is easily distinguishable from the Mesilla Valley Formation below. Although the base of the Mojado Formation was originally defined arbitrarily by the thickness of sandstone interbeds, or a change in sandstone lithology, we see a distinct change in ichnoassemblages between these two Formations, which may be used to define the contact in the future.
作为对最底层Mojado组Albian Sarten成员的痕迹化石的持续调查的一部分，我们报告了在新墨西哥州桑兰公园的Cerro de Cristo Rey的首次描述。单纯弧菌是一种水平的，三叶状的痕迹，被解释为一种螺旋体。该组合中通常与克鲁齐亚纳鱼相相关的其他痕迹包括Thalassinoides、Arthrophycus、Planolities、划痕(以及其他尚未报道的)。我们的弯曲岩标本仅保存在铁染的大块砂岩的凸面上，这些砂岩与薄的灰色页岩互层。在这个位置，萨滕成员的较低接触很容易与下面的梅西拉山谷地层区分开来。虽然Mojado组的基底最初是由砂岩互层厚度或砂岩岩性变化随意确定的，但我们发现这两个组之间的岩石组合有明显的变化，这可能用于确定未来的接触。

Earth resistivity measurements near Fort Stanton Cave were begun shortly after the discovery of the Snowy River passage in 2001. Resistive anomalies were frequently detected ahead of the progress of underground exploration and survey of the cave passages, and later shown to represent cave passages when the survey lines passed through the anomalies. Many other anomalies are present between and adjacent to the passages currently known.

The Early Cretaceous (late Albian) dinosaur tracksite at Clayton Lake in Union County encompasses approximately 533 dinosaur tracks, 182 of which are organized into 28 trackways. Most of the trackways were made by bipedal ornithopod dinosaurs, but two trackways were made by bipedal theropods, and one was made by a quadrupedal ankylosaur. To estimate dinosaur speeds from the trackways, we employed the methods of Alexander (1976, 1989) and Thulborn (1990) that rely on footprint lengths and strides as the raw data from which to estimate size and speed. On the Clayton tracks, we measured total length and width as highest edge to highest edge (rim to rim) of the maximum track shape. Though not ideal, this approach was dictated by the quality and nature of track preservation and provided a consistent methodology. For deeper tracks, these measurements are similar to the “negative vertical displacement” approach, but less than the “maximum zone of deformation.” This approach neither captures the true footprint dimensions nor the full extent of extramorphological variation but does represent the maximum lengths and widths on the bedding plane surface. Track length was measured from the anterior tip of digit III to the base of the “heel” margin, actual or inferred. In some cases, our measured track lengths exceed the true foot length of the trackmaker, and these tracks are unsuitable for size and speed estimates. However, some trackways have a “best” track(s) that exhibit(s) some combination of clear track outline, high angle footwalls, and “impressed” positives. We estimated size and speed for these. The results (using the method of Alexander, 1976) are that all of the ornithopod trackways show walking speeds of ~ 2-to 7 km /hour. The relatively fastest dinosaur speed at Clayton Lake may be
