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
PRESIDENTIAL ADDRESS 2:THE END PERMIAN MASS ExTINCTION: DEATH BY FIRE
Professor Paul Wignall
The international type section of the
Permian/Triassic Boundary, Meishan, SE
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.
www.yorksgeolsoc.org.uk YGS 2010 7
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.
