Iberian Dogster Phenomenon (Arantxa Daza Perea, 2017)

Beginning sometime between the LN and Early Iberian Chalcolithic, dog remains start appearing in notable arrangements: in people burials, in pits and apparently near ditch entrances of ditched enclosures.  These dog depositions are significant enough and strange enough to say that there exists an 'Iberian Dogster Phenomenon'.

This paper by Daza begins looking at Peninsular dogs from the Late Neolithic to the Bronze Age beginning with, at least in this preliminary paper, grading on osteometric traits against other populations.  Already the results are surprising as all Neolithic dogs are tightly clustered.  However with the apparent emergence of the Bell Beaker phenomenon, it is possible to see greater morphological diversity that begins moving toward modern improved breeds.

There are several interesting formats in which dogs are found, but one that sticks out begins in the Iberian Bronze Age when dogs often appear in child burials.  Within the context of Bronze Age beliefs about the sequence of events following death, these dogs may have been intended to help shepherd children through the underworld.  Dog #7 is one such child-shepherd.

But the most interesting dog in this set is dog #1 as seen below in the Canonical Variate Analysis below.  This dog was buried with a Bell Beaker man in the Meseta (plateau) region of Spain.  If I am reading this correctly, it appears that the dog clusters with a morphology consistent with a sighthound.

For this body-type to be found within the pseudo-steppe ecology of the Spanish grasslands is fairly significant, since it strongly suggests that this was a working dog.  Dog #1 appears between the physical dimensions of a greyhound and the pre-Columbian viringo (being that the modern dog reference set was limited to only a few major types).

#6 was a ditch dog and is kind of hovering out there by itself.  In any case, this is the preliminary paper, a thesis will follow, and then apparently a larger study.

On that note, I pasted this from the Perdigoes research blog last year.  This is the presentation, publishing may follow:
"...a synthesis about the Bell Beaker phenomena at Perdigões will be presented at a meeting to be held in the University of Lisbon next May."
This will be interesting because Perdigoes is large and old, but also because it is within a geological region that likely supplied copper ingot or works to the castillos on the coast.  So something interesting may have gone on at this location.  Also from the Perdigoes research blog, there will also be before long a very large archaeogenetic study on ancient Iberian aurochs and cattle.

Abstract
This paper aims to highlight developments in archaeological knowledge relating to dog remains found in deposits from Late Prehistoric contexts at sites along the Iberian Peninsula. Preliminary results from ongoing osteometric and 2D Geometric Morphometric studies applied to these remains are here presented and discussed to contextualize future studies by the author.

  1. Unsure if any connection, but geographically Iberia is in between:

    1. That's awesome. Thanks for sharing.

      It will be interesting to see the understanding develop on Bronze Age dog classes because this will have huge implications. For example, dog #1 is located in the Meseta and it is obviously improved, and of course rabbit hunting was a very big deal for ancient Iberians so the context makes connecting dots a bit easier.

      Another area of interest is the physique of common flushing hounds like modern spaniels, pointers and setters. There is some evidence of hawking in the Beaker period and dogs are commonly used to flush quarry.

  2. Bell Beakers don't seem like cat people to me, although you never know. I haven't seen any cat remains mentioned yet.
