Were Going BIG This Fossil Friday. Like, Really Big. At 122 Ft (37.2 M) Long, Patagotitan Mayorum Is

We’re going BIG this Fossil Friday. Like, really big. 🦕At 122 ft (37.2 m) long, Patagotitan mayorum is the Museum’s largest dinosaur on display and one of the largest animals to have ever walked the Earth! This gigantic herbivore, which lived some 95 million years ago during the Late Cretaceous, was heavier than 10 African elephants—tipping the scales at roughly 70 tons. In fact, The Titanosaur is so big that it barely fits in the Museum’s halls: It’s longer than the gallery it sits in—and its head, which would graze the ceiling, extends outwards toward the elevator banks! We're open daily from 10 am-5:30 pm! Plan your visit.

HiPOD: Layered Deposits in Uzboi Vallis

Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it. These deposits may record deposition into a large lake that once filled Uzboi Vallis when it was temporarily dammed at its northern end by the rim of Holden Crater and before it was overtopped and breached allowing water to drain back out of the valley.

Layered deposits similar to those here may remain preserved where they were protected from erosion during drainage of the lake. Data from the CRISM instrument onboard MRO shows that clays are within these deposits that may differ from clays found elsewhere on the valley floor. Hence, the clays in these layers may have been washed into the lake from surrounding clay-bearing surfaces. (Enhanced color cutout is less than 1 km across.)

Holy shit holy shit holy Schist!!!!!

A hydrothermal explosion happened Yellowstone!! And I’m alive to see it! I wish I was there.

From USGS Facebook:

A small hydrothermal explosion occurred in Yellowstone National Park today (July 23, 2024) around 10:00 AM MST in the Biscuit Basin thermal area, about 2.1 miles (3.5 km) northwest of Old Faithful. Numerous videos of the event were recorded by visitors. The boardwalk was damaged, but there were no reports of injury. The explosion appears to have originated near Black Diamond Pool.

Biscuit Basin, including the parking lot and boardwalks, are temporary closed for visitor safety. The Grand Loop road remains open. Yellowstone National Park geologists are investigating the event.

Hydrothermal explosions occur when water suddenly flashes to steam underground, and they are relatively common in Yellowstone. For example, Porkchop Geyser, in Norris Geyser Basin, experienced an explosion in 1989, and a small event in Norris Geyser Basin was recorded by monitoring equipment on April 15, 2024. An explosion similar to that of today also occurred in Biscuit Basin on May 17, 2009.

More information about hydrothermal explosions is available at https://www.usgs.gov/observatories/yvo/news/hydrothermal-explosions-yellowstone-national-park.

Monitoring data show no changes in the Yellowstone region. Today’s explosion does not reflect activity within volcanic system, which remains at normal background levels of activity. Hydrothermal explosions like that of today are not a sign of impending volcanic eruptions, and they are not caused by magma rising towards the surface.

Additional information will be provided as it becomes available.

The Yellowstone Volcano Observatory (YVO) provides long-term monitoring of volcanic and earthquake activity in the Yellowstone National Park region. Yellowstone is the site of the largest and most diverse collection of natural thermal features in the world and the first National Park. YVO is one of the five USGS Volcano Observatories that monitor volcanoes within the United States for science and public safety.
