While researching anomalous events , our attention was drawn to text from a discussion regarding unusual characteristics of the surface outcrop in Belize's Boundary Stratigraphy at the Albion Quarry (AQ). An excerpt is shown here:

"Diamictite in Belize is like direct ejecta from other craters in carbonate terrain, notably the 15-Myr old Ries Crater ejecta in Germany, in that high percents of both the matrix and large clasts are locally derived (Horz and Banholzer, 1980). However, the diamictite in Belize lacks significant amounts of glass and glass byproducts and is internally bedded, among other significant differences with Ries ejecta."Bedding in Belizan ejecta diamictite is particularly interesting because it suggests that different parts of the ejecta flow were moving at slightly different speeds or took slightly different flow paths. Further, it is possible that the layers were deposited at significantly different times or originated at different points. The similarity of sedimentary structures and textures within beds suggests that common processes were operative within each sedimentological unit during emplacement. It is unclear at this time what role secondary impacts may have had in rearranging diamictite stratigraphy, but such impacts may help explain bedding characteristics.""Belize ejecta is also notable for its lack of 1) shocked quartz (and other shocked framework silicates), 2) iridium-bearing sediments, and 3) true tektites "



The PZ hypothesis may offer an explanation for the unusual amount of unstratified and undifferentiated sand and gravel deposits as well as intact strata with seemingly dislocated magnetic alignment or unusual geomorphic characteristics, across the globe. The theory suggests that a series of cometary impacts from elements of the Taurid stream is responsible for these landforms. The terrestrial ejecta landforms identified by the theory often manifest themselves as ovoid, teardrop shaped landforms, or distributed in teardrop shaped arrays.

Our investigation shows that the area the Yucatan peninsula is indicative of being overlaid by terrestrial ejecta from a Perigee: Zero impact. We are aware of the immediate location of the Chicxulub crater, however our deduction is drawn from the satellite photographic record of the area. This discussion in no way detracts form the solid evidence of that crater's existence, although we do question the existence of surface-level unconsolidated strata being attributed to events 65 million years ago. Any sedimentary or ejecta strata from that age should have been eroded into the ocean long ago. Normally a glacier would be assumed as causal, but that certainly won't work here.

The expected characteristics of our PZ ejecta do not include high quantities of glass or glass byproducts due to the high percentage of water in the ejecta waves and the "power wash" action of the trenching comet body. The ejecta is excavated with shearing force, so no shock cones are expected. The PDF graphic attached identifies the indicated span of the emplacements, ovoid - teardrop shaped fields we interpret to be terrestrial ejecta from a comet impact event. Additional PZ ejecta correlation with the paper's description of the Belizian ejecta comes from the expected accretion over the ejecta field by components arriving at slightly different time, and from different locations along the linear cratering path.The Goggle map service presents the satellite photo of the zone described. In the graphic below, we display our generic ejecta overlay on the Yucatan to offer a suggested ejecta emplacement.

The Albion Quarry is along the souther boundary of thee fields.The location of the Perigee: Zero impact event responsible for this ejecta is interpreted as being located SE along azimuth 135º.

We have placed the timing of this event at ~900 AD, coincident with the rapid decline of Mayan population centers in the lowlands of the Yucatan.

"During the 9th century the population centers of the central lowlands declined significantly. This decline was very rapid and is attributed to famine, drought, breakdowns in trade, and political fragmentation. .... As the cities in the lowlands declined, urban centers sprung up in the Northern Yucatán, including Uxmal (near Mérida)."
