In a note to palaeontologists, this further information was compiled. It gives a brief overview pending the publication of correlated geological data:
"The geology of the era matches exactly what I now propose. In Wales and elsewhere we have huge lias deposits and near my home there are vast clay beds hundreds of feet deep as reminders of the huge shallow lakes that existed for millions of years; where as in the USA we have the Morrison Formation - at least 1,600,000 km2 of those rocks in the USA alone. Reinterpreting the geological findings has given me endless substantiation for my view. Those strata are all siltstone, mudstone, limestone and sandstone; they are sedimentary and are the legacy of the of vast shallow lakes I now propose.
"The accepted interpretation as 'flood plains' is unsatisfactory.
"In the Morrison strata you have the huge sauropod fossils throughout these beds; all are characterized by elongated necks and high body mass. The conventional interpretation is for seasonal lakes with grazing dinosaurs at the periphery; I argue that the body mass is unsustainable and conclude instead that the dinosaurs evolved as essentially aquatic genera walking on the mud at the bottom of enduring shallow lakes. The mass of their bodies, being of neutral density, was borne by the surrounding water rather than by the limbs; and wherever you see reconstructions it seems clear to me (as a biologist) that the drawings and models make far more sense if – in the mind’s eye – one envisions them being largely immersed in water. The theory also accounts for the shallowness of the fossil footprints (the vast mass of sauropoda would have led to them becoming entrapped in alluvial mud were they walking on land).
"It also answers one of the main metabolic controversies - dinosaurs seem to have the properties of homoeothermic organisms, yet all the reptilia are poikilothermic; according to my theory, their immersion in lakes provides the thermal buffer an an aquatic environment. The fact that the mean water temperature was about 37'C is a further supportive factor. They could thus have the metabolic constancy of endotherms coupled with ectotherm physiology ..."
Journalists were briefed on the topics they might raise with conventional palaeontologists, which the new theory alone can address:
a) How dinosaur limbs could otherwise have borne such weight
(up to 100 tonnes)
b) Why they would expend such a large amount of metabolic energy holding tails erect
(There are no tail drag marks in the fossil footprints; there are for crocodiles)
c) How they maintained their steady body temperature without the cushion of a huge body of warm water
(Isotope analysis shows they maintained a constant body temperature and no reptiles evolved a mechanism to do so)
d) Why the abundant fossil footprint are proportionately comparable
(They'd have sunk up to the armpits were they standing on dry land)
e) Why they claim that Spinosaurus - and a host of similar dinosaurs! - simply dipped their heads beneath the waves
(Their snout glands are like those of crocodiles; clearly they spent most of their lives in water)
Further details will be posted above as further publications and presentations appear.
