pollen, however, is known to be under-represented 
in palynological records and investigations in north 
Germany have suggested that cereal pollen may not 
be recorded in deposits at distances greater than 
one kilometre from a site and even by 500 m little is 
recorded (Behre and Kucan 1986). 
Aquatic plants 
The absence of substantial evidence for aquatic 
plants or organisms in the pollen profile suggests 
that when the sediments were forming the 
waterhole was kept clean of vegetation, or utilised 
in such away as to prevent the water becoming 
stagnant and plants such as_ waterlilies or 
pondweeds colonising. 
The later use of the waterhole 
A high percentage of pollen grains in the sample 
from 0.66-0.665 m are crumpled or badly corroded 
precluding identification. A high percentage of 
dandelion-type pollen, which is resistant to 
corrosion and easily identified, however poor the 
pollen preservation, indicates that some of the 
pollen may be derived from secondary deposition. 
The likelihood of material either washed or thrown 
into the waterhole, supports the possibility that the 
fill 419 results from the disposal of rubbish. 
Conclusions 
In conclusion, this analysis has indicated that the 
settlement at Latton Lands was not delimited on 
two of its four sides by trees, and that woodland was 
less important to the local environment in 
comparison with Latton ‘Roman Pond’. 
RADIOCARBON DATING 
Two samples, both of waterlogged wood, were 
submitted to the Radiocarbon Dating Laboratory 
at the University of Waikato, New Zealand. The 
results are summarised in Table 16 below. Sample 
no.8 was recovered from layer 481 (an organic rich 
deposit associated with further waterlogged wood 
including part of a wooden bowl) within waterhole 
42] (Figure. 5) and was also associated with Deverel- 
Rimbury style pottery . 
The aim of the dating programme was to 
establish the date of the waterhole in relation to the 
middle Bronze Age (1500-1150 cal BC) sequence, 
and to provide an associated date for the wooden 
bowl (SF109) and for the lower part of the pollen 
sequence (Sample 9). Figure 21 and Table 16 
demonstrate that the two radiocarbon results 
obtained are virtually indistinguishable at the two 
sigma range and confirm the date of the waterhole
