The Papaloapan rises in the Sierra Madre Oriental on the border between the states of Veracruz and Oaxaca.

The Colorado River Delta is the region where the Colorado River flows into the Gulf of California,. The delta is part of a larger geologic region called the Salton Trough. Historically, the interaction of the river’s flow and the ocean’s tide created a dynamic environment, supporting freshwater, brackish, and saltwater species. Within the delta region, the river split into multiple braided channels and formed complex estuary and terrestrial ecosystems.

The SC/MP from National Semiconductor is an early microprocessor, which became available in early 1974. The name SC/MP (pronounced "Scamp") is an acronym for: "Simple Cost-effective Micro Processor". It features a 16-bit address and an 8-bit data bus. The program counter will roll-over on 12-bits (4096), there are separate instructions to alter the program counter to set the upper 4-bits, which are subsequently output on the address bus along with status signals.
Madtsoiidae are an extinct group of mostly Gondwanan snakes with a fossil record extending from early Cenomanian to late Pleistocene strata located in South America, Africa, India, Australia and Southern Europe. Madtsoiid snakes include very primitive snakes, which like extant boas and pythons would likely dispatch their prey by constriction, such as Gigantophis, one of the longest snakes known at an estimated 10.7 meters, and the Australian Aboriginal mythology-named Wonambi and Yurlunggur.
