SuBSCRIPTIONS

Traditionally a summary of the accounts has been published in this circular prior to the AGM.

This has not been possible for the financial year ending 31 August 2010. A full set of audited

accounts will be presented to the AGM in Leeds and published as part of the Society’s

annual report.


The end-Permian mass extinction was the greatest crisis ever to be faced by life on Earth.

Even conservative estimates of the extinction losses recognise that less than 10% of species

survived. Almost unique amongst such extinction crises, the event affected the entire

biosphere including groups that are normally resilient to such calamities including the insects

and plants. Thus, the high-latitude forests of the southern hemisphere characterised by

Glossopteris leaves went abruptly extinct. So severe was the effect on global plant

communities that peat-forming conditions disappeared for several million years of the

succeeding Early Triassic with the result that there is a unique “coal gap” at this time. In the

oceans there is an equivalent “chert gap”. Chert is a siliceous rock made up of the tiny

skeletons of radiolarians, the dominant fossil plankton group for much of the Phanerozoic.

For hundreds of millions of years

radiolarians rained down to the seabed

where they formed a slowly accumulat-

ing siliceous ooze that over time

hardened to form chert. This chert

record temporarily disappears in the

Early Triassic to be replaced by

organic-rich shales: black shales.

The last two decades have seen a

dramatic increase in studies on the

end-Permian mass extinction and, in my

second Presidential address, I will review

some of this research and focus on the

ideas that have been put forward to

explain this crisis. The Siberian Traps

The international type section of the

China. The rocks consist of alternating limestones and shales with a pale, rustyweathering ash band. The mass extinction

is recorded in the limestone immediately

above the hammer head, and below the ashband, whilst the Permian/Triassic boundary is just above the top of the hammer shaft at

a level of a bedding plane within a limestone

bed. Except for the ash band, these strata

accumulated very slowly and record several100 thousand years of deposition in a deep

marine setting.


have emerged as by far the most popular “culprit”. The Traps are the remnants of a

formerly vast expanse of flood basalts that erupted onto the West Siberian craton at

precisely the same time as the mass extinction. Only half a million cubic kilometres of this lava

currently remain but the original volume has been estimated as up to ten times this

amount, making it the greatest manifestation of terrestrial volcanism known on Earth. The best

link between this volcanism and the extinction comes from the timing; a link that is also

strengthened by the fact that other similar flood basalt eruptions have coincided with other

extinction events (as discussed in my first Presidential address). However, the actual “kill

mechanism” has proved elusive. How can giant lava flows in Siberia kill tropical reefs in South

China? The Siberian eruption style is

likely to have been dominated by fire

fountains. These are great walls of

ascending lava, which may have been

several kilometres high, extruded from

fissures tens to hundreds of kilometres

in length. Whilst obviously impressive,

this is not the most effective eruption

style for injecting material into the

stratosphere. Thus, typical effects of

volcanism, such as cooling caused by

stratospheric aerosols and dust need

not necessarily have been as severe as

expected from the scale of the

volcanism. Nonetheless, most geologists

link the Siberian eruptions and the

end-Permian extinctions via a series of

steps connected to the atmospheric

effects of the eruptions. The two

principal volcanic gases (other than

harmless water vapour) are sulphur

dioxide and carbon dioxide. The former

generate clouds of sulphate aerosols

and are rapidly removed from the

atmosphere as acid rain. These effects

operate over just a few years, a

geological instant; whereas carbon

dioxide’s well-known greenhouse effect

is more pernicious and protracted. The observed stagnation of the world’s oceans and shift

to black shale deposition has been linked to stagnation related to warming and this may form

the ultimate link with volcanism and extinction.

Problems still remain with this volcanic link: gas emissions are large but, when modelled, do

not appear to be excessively so. More indirectly, almost-as-large volcanic eruptions at other

times are not linked with extinctions which begs the question: what was so lethal about the

Siberian eruptions? A possible solution to the extinction-volcanism impasse may come from

consideration of the indirect effects of flood basalt eruptions. Such volcanism requires the

passage of huge volumes of magma through the upper crust where it will have a baking effect

on sedimentary rocks. Given the wrong kind of rocks some of the gases released by this

sediment baking could be especially damaging. Thus, recent papers have highlighted the

nature of the subsurface geology in western Siberia and the possibility that thermal

metamorphism may have released lots of especially noxious gases such as methyl chloride.

Such halocarbons affect the production of atmospheric ozone raising the possibility of an

Earth without an ozone shield.

Finally, like all mass extinction studies, there are plenty of other competing theories that do

not involve volcanism. Inevitably these include giant meteorite impact but, despite several

claims, substantive evidence is lacking. Even less plausible ideas invoking death from outer

space include the transit of the Earth through an especially dense patch of dark matter and

the effects of a nearby supernova. Imaginative as these ideas are, it remains likely that the

great end-Permian mass extinction was caused by Earth-bound causes.

The meeting assembled at the small car park at Crook Ness and twenty members and guests

enjoyed a bright September day in which the threatened rain never materialised beyond a

short blustery shower.

After descending to the shore the leaders introduced the stratigraphy of the Ravenscar

Group and of its highest unit, the Scalby Formation. In particular they discussed the Long

Nab Member (Nami & Leeder 1978) and also gave a brief account of the three

sedimentary prisms recognised by Eschard et al. (1991), since the top of Prism III is well-

displayed on the shore in Burniston Bay as sandstones of a meander belt. The group then

examined the succession by the steps, which shows the junction between the top of Prism

III and the overlying, more flat-lying, mudrocks and sandstones which make up the upper part

of the Long Nab Member (the Level-Bedded Series of Black 1929). Tridactyl footprints

were seen both in situ in the overhanging base of the Burniston Footprint Bed (Romano

and Whyte 2003) and in loose blocks on the shore.

The group then walked south to

Cromer Point and spent much of the

rest of the day examining the

exposures within Burniston Bay,

between Cromer Point and Crook

Ness, before finally, towards the

end of the day, looking at outcrops

to the north of Crook Ness. At

Cromer Point the group clambered

onto and examined cross-bedded

sandstones deposited within a small

channel which cuts down from the

Level-Bedded Series into the top of

Prism III. The channel is capped by

a heavily dinoturbated sandstone

(Fig.1) and within the channel

sandstones other disturbances caused by dinosaur footprints were examined. One

particularly large transmitted print of a sauropod dinosaur was pointed out and discussed.

The leaders explained the detailed sedimentary logging that they had done round Burniston

Bay and demonstrated some of the sedimentary features and associated footprints and other

trace fossils. Structures seen and placed within the local succession included heterolithic

sandstones with syneresis cracks and footprints, mud filled channels cutting down into the

Burniston Footprint Bed, palaeosols with rootlets, sphaerosiderite and sandstone dykes,

rippled surfaces, beds with climbing ripple structures, and penecontemporaneous rotational

slips within channel fills. Particular attention was given to a sheet sandstone on the base of

which there are spectacular gutter casts. This sandstone also displays Ophiomorpha-like

burrow systems, infilled shrinkage cracks and dinosaur footprints and is in places cut out by

an irregular erosion surface. Other tridactyl and sauropod footprints were also seen

including a well-displayed tridactyl print on a block which had fallen from a higher sandstone

horizon. Typically some of the exposures and loose blocks examined showed abundant

plant material and there was debate about one particular specimen, preserved at a high

angle to the bedding, which was

considered to be either a root bundle

or a stem. The leaders also drew

attention to a thin bed of fine-grained

sandstone, whose consistent set of

internal structures led them to interpret

it as an event bed. Structures on the

base of this bed are more problematical

and the leaders each outlined their

contrasting theories as to the origin of

these structures.

One of the highlights of the day was the

discovery of a large block with an

extensive bedding surface bearing the

walking trackways of several horseshoe

crabs (Limuloid xiphosurans) (Fig.2).

The preservation of the small delicate prints in these

trackways highlights one of the features of the

Yorkshire dinosaur ichnofauna, namely the scarcity of

very small dinosaur footprints. The leaders have

previously recorded horseshoe crab traces from

elsewhere in the Ravenscar Group (Romano &

Whyte 1996,1997, 1999).

After the end of the meeting, some members of

the group extended their visit northwards to

examine boulders on the shore south of Long Nab.

Here they saw a number of blocks with fine tridactyl

footprints (Fig. 3) including a block with several

dinosaur trackways.
