Coral Pinnacle Sedimentation, Alacran Reef Lagoon, Mexico: ABSTRACT
AAPG Bulletin, 1966Coral pinnacles growing in Alacran Reef lagoon can be characterized by three different depositional environments. These are: (1) pinnacle crest--a rigid framework of living colonial corals and unconsolidated sediment which is poorly sorted, consisting of 2.5^phgrv coral sand, with relatively high permeability, 20% calcite (90% aragonite), and 1-1.7 ...

Opisthobranch fauna from the National Park Arrecife Alacranes, southern Gulf of Mexico
2012The opisthobranch mollusks recorded in the National Park Arrecife Alacranes, a marine protected area and the largest coral reef in the southern Gulf of Mexico, were studied during three survey periods in 2009-2010. Several substrate types: rocks, sponges, corals, sand, Thalassia beds and drifting Sargassum were analyzed.

A new species of Alacran (Scorpiones: Typhlochactidae) from a cave in Oaxaca, Mexico
Zootaxa, 2009Alacran chamuco sp. nov., a new eyeless, troglobitic scorpion from Te Cimutaa, Valle Nacional, is described. This is the second known species in the genus; sharing with Alacran tartarus a very similar trichobothrial pattern and the lack of “petite” trichobothria—both unique characters in the family Typhlochactidae.

Thickest recorded Holocene reef section, Isla Pérez core hole, Alacran Reef, Mexico
Geology, 1977The Isla Perez core hole (Alacran Reef, Mexico) records the thickest Holocene section (33.5 m) known from either Atlantic or Indo-Pacific reefs. The high rate of deposition of reef material—a maximum of 12m/l,000 yr—is attributed to accumulation of the open framework constructed by the rapidly growing coral Acropora cervicornis .

Island Transport of Marine Shells by Birds on Perez Island Alacran Reef, Campeche Bank, Mexico
The Journal of Geology, 1962The Brown Noddy Tern (Anoiis stolidus) lines its nest with marine shells and debris. The weight of shells in ten nests on Perez Island, Alacran Reef, Campeche Bank, totaled 12,435 gms. The shell accumulations in nests contain species common to shell deposits on nearby beaches.
