Describes the chronological occurrences of the Pre-Classic mushroom stones in 
the Central Highland area of Guatemala. Asserts that simple stone sculpture probably 
begins during the Early Pre-Classic Las Charcas phase (1000 to 500 B.C.) in the 
Maya Highlands with the fashioning of effigy mushroom-like objects. Also mentions 
the finding of the Jaguar-shaped tripod mushroom stone (Type B) in tomb 1, at 
Mound E-III-3 at Kaminaljuyu (cf Shook and Kidder, Entry 103, p 112, fig 78f, and 
no 15 in Borhegyi’s chart, above cited). Shook’s premise, that mushroom stones were 
manufactured during the Las Charcas phase, is not yet fully substantiated. However, 
mushroom caps (Type A) were discovered in Las Charcas deposits (Guatemala 
National Museum, Lot nos C-s50, C-69, C-43) and are reproduced as nos 8, 10, in 
Borhegyi’s chart. It is also possible that the jaguar mushroom stone (no 12 in Bor- 
hegyi’s chart) is of Las Charcas date.

Shook and Kidder describe the finding of an exquisitely carved tripod effigy mush- 
room stone (Type B) in the rich Mid-Pre-Classic (Miraflores phase, 300 B.C. to 200 
A.D.) tomb 1 at Kaminaljuyu. This jaguar-shaped mushroom stone is reproduced 
as no 15 in Borhegyi’s chart. Kidder and Shook earlier contended (1946) that 
mushroom stones are products of the Classic period. The finding of this mushroom 
stone in a sealed Miraflores phase tomb (fig 13, no 193) establishes with finality that 
at least certain types of mushroom stones (Types A, B, C) are of Pre-Classic date, 
and that the mushroom stone cult among the Highland Maya was in vogue as early 
as 300 B.C. The specimen is now in the Guatemalan National Museum collection 
(Cat no 3450). This Pre-Columbian jaguar mushroom stone is the first reported from 
a tomb.

In his archeological survey of the Central Guatemalan Highlands, Shook describes 
103 archeological sites, their location, architecture, and the specimens collected 
from each site. Seven sites yielded mushroom stones of the effigy (Type B and C) 
and tripod (Type D) variety. The seven sites are Aeropuerto, Agua Caliente, Alux, 
Aurora, Cementerio, Eucaliptus, and Kaminaljuyu. They are reproduced as nos 2, 3, 
4, 8, 10, 12, 13, 15, 17, 18, 19, 20, 27, 28, 29, 31, 38, 39, 40 in Borhegyi’s chart 
Shook’s article represents the first attempt to survey the distribution of mushroom 
stones in the Central Guatemalan Highlands. Most of the specimens referred to in 
Shook’s article are in the collections of the Guatemalan National Museum.
