Supplementary Figure 1 | 238U-234Th isotope activity ratio plot for all measurements on coralline bone coatings from Leaena’s Breath Cave. Three coatings were analysed, here shown in different colours. Most of this material was observed to be chalky and potentially altered prior to analysis and indeed plots to the right of the 1000 kyr isochron, which is not possible through closed-system U-series decay and means ages cannot be calculated. The least-altered (on the basis of physical appearance) sub-samples of each of the three coatings are shown in bold and with one exception resolve finite age estimates. Whilst it is likely that the least-altered subsamples are themselves altered in the same sense (i.e. towards larger values of both isotope ratios shown) and thus in this case overestimate their ages, it is unlikely that the degree of alteration is large relative to the most-altered subsamples, again on the basis of observed differences in physical appearance. The best-preserved sub-sample of LBC Cor03 (here shown in bold green) lies on the U-Th evolution curve predicted by the initial [234U/238U] ratio of ~0.8 (bold curved line) observed in well-preserved coralline samples from LTC, making its apparent age of ~390 kyr the most reliable estimate determined from these samples.

Optical dating
Optical dating provides an estimate of the time elapsed since luminescent minerals, such as
quartz, were last exposed to sunlight2–4. In this study, therefore, the event being dated is the time of
entry of the sediment grains into the Thylacoleo Caves. Buried grains will accumulate the effects of the
nuclear radiation flux to which they are exposed, and the burial dose (palaeodose) can be estimated
using the optically stimulated luminescence (OSL) signal. Optical ages were calculated from the
palaeodose divided by the dose rate due to ionising radiation (Supp. Table 2).
We extracted quartz grains of 90–125 µm diameter from the sediment samples under dim red
illumination using standard procedures, including etching by hydrofluoric acid to remove the external
alpha-dosed layer2. Palaeodoses were obtained from aliquots composed of between ~8 and ~800 grains
(to check for insufficient bleaching of the quartz grains at deposition), using the single-aliquot
regenerative-dose protocol, statistical models and experimental apparatus described elsewhere5,6.
Aliquots were stimulated using either blue (470 nm) or green-plus-blue (420–550 nm) light for
100 s at 125 °C, after a preheat of 160–300 °C for 10 s (or a cut-heat to 160 °C for test doses). The
ultraviolet emissions were detected by an Electron Tubes Ltd 9635QA or 9235QA photomultiplier tube
fitted with 7.5 mm of Hoya U-340 filter, and laboratory doses were given using a calibrated 90Sr/90Y
beta source. Palaeodoses were determined from the first 3 s of OSL, using the final 30 s as background.
Standards tests of protocol performance were made (e.g., preheat plateau and dose recovery tests,
and checks on thermal transfer and test-dose sensitivity correction), which revealed no significant
problems for any samples. In addition, samples were analysed at two OSL laboratories using different
instruments, and the resulting palaeodoses were in agreement.
For four of the samples (FS02, LT02, LB01 and LB02), the natural OSL signals from most
aliquots were saturated with respect to dose, so only minimum (infinite) palaeodoses and ages could be
obtained. By contrast, some aliquots of samples FS04 and LT01 gave palaeodoses well below the
saturation limit (~200 Gy). A minimum age model5 was used to estimate the smallest finite palaeodose
for each sample. This conservative approach takes into account any bias due to small palaeodoses for
aliquots composed of grains that experienced below-average beta dose rates, as can occur in limestone
cave deposits7.
A pulsed-irradiation regeneration technique8 was applied to sample LB02 to ensure that the
palaeodoses had not been overestimated; no reduction in palaeodose was achieved. Additional tests
were made on sample LB02 in an attempt to measure larger finite palaeodoses. A search was made for
individual ‘supergrains’ of quartz9, and other proposed methods for extending the age range of
luminescence dating were also explored10–12, but without success.
The total dose rate for each sample was calculated as the sum of the beta and gamma dose rates
due to 238U, 235U, 232Th (and their decay products) and 40K (making allowance for beta-dose

www.nature.com/nature 4
attenuation13 and sample water content14), which were deduced from the radionuclide activities
measured by high-resolution gamma-ray spectrometry15. Account was also taken of the cosmic-ray
contribution (adjusted for site altitude, geomagnetic latitude, and thickness of rock and sediment
overburden)16 and the effective internal alpha dose rate (estimated from measurements made previously
on quartz grains from southeastern Australia17). Gamma rays can penetrate up to 30 cm through most
soils and sediment, but none of the samples was buried this deeply. Accordingly, the gamma dose rate
for each sample was adjusted using Table H.1 of ref. 14.
For all samples, a condition of secular equilibrium currently exists in the 232Th decay series, as is
commonly the case for Australian terrestrial sediments7,15, but the 238U decay series is in disequilibrium.
The 210Pb/226Ra ratios are consistent with 11–35% loss of radon (222Rn) gas to atmosphere, as observed
previously for cave sediments on the Nullarbor Plain7; we assume that the measured ratios prevailed
throughout the period of sample burial. Samples FS02, LT01, LT02 and LB02 also exhibit 13–35%
excess of 238U with respect to 226Ra, which we attribute to the incorporation of bone in the sediment
samples and the absorption of uranium by bone after burial. But the presence of excess uranium of this
magnitude has a negligible effect on the total dose rate7,15 and would, in any case, make the optical ages
appear younger. Hence, use of the minimum age model is appropriate in this context also.

Supplementary Figure 2 | Palaeomagnetism results from the test excavation in Leaena’s Breath Cave, plotted as latitude of Virtual Geomagnetic Pole against sediment depth. All
samples from the upper 6 monoliths contain a stable magnetization of normal polarity
(northerly declination and negative inclination). NRM intensities were moderately strong, in the
range 130–420 mA/m. Samples from the lower two blocks are characterized by a low
coercivity component (removed by a.f. level <10 mT) of normal polarity and a stable high
coercivity component of reversed polarity (southerly declination and positive inclination).
Results are summarized in Supp. Table 3. The mean direction of the 18 normal samples is
statistically indistinguishable from that of the 6 reversed specimens, and also not significantly
different from the dipole field direction for the latitude of the site. Calculated Virtual
Geomagnetic Pole (VGP) latitudes define an upper zone of normal polarity and a lower zone
of reversed polarity, interpreted to represent the Brunhes Normal Chron and the Matuyama
Reversed Chron respectively. Thus the Matuyama/Brunhes boundary, with an estimated age
of 0.78 Ma19, is placed between 50 and 70 cm depth.

Depositional environments
Fossils within the Thylacoleo Caves, large collapse chambers floored by boulder piles and
sediment expanses (Supp. Fig. 4a) and entered via narrow solution pipes (Supp. Fig. 4b), occur in three
general contexts:
1. Cave floors. Fossils lie atop or wedged between boulders, or atop sediment expanses.
Specimens may be complete skeletons, which have sustained minimal disturbance since death (Supp.
Fig. 4e–f), partial skeletons (Supp. Fig. 4g), or isolated subassemblies or elements (Supp. Fig. 4h). The
distances of many skeletons from the photic zone below the entrances indicates that animals survived
falling into caves. Species across a broad size range (0.01–250 kg) have been retrieved from cave floors,
but smaller species are rarer due to higher chances of disintegration or loss down fissures.
2. Infill sediments. There are two major silty clay expanses in the Thylacoleo Caves. The largest
is a 510 m2 expanse in Leaena’s Breath Cave (LBC) (Supp. Fig. 4d). While sequence depths are not yet
known (a test excavation extended down to 1.3 m), it is probably several metres deep. Remains of
dasyurids, bandicoots, murid rodents, lizards and birds predominate.
3. The Ossuary (Supp. Fig. 4c). A sink deep in Last Tree Cave (LTC) contains a dense
concentration of bones resting atop and within sediment formed from limestone breakdown. No
erosional or breakage-pattern features suggest sediment winnowing or bone transport by water, although
water likely ponded in this area during moister intervals (see below). Fossils are among the best
preserved in the caves. Associated remains are common, and complete skeletons have been found below
the surface. As one of the two lowest points in LTC, there was evidently a tendency for animals to move
toward the Ossuary. We suggest that the deposit largely represents a carcass gravity lag. Carcasses
mummified in the cool, dry conditions (as is common with Holocene material in Nullarbor caves24),
then gradually slid down due to the effects of gravity and disturbance upslope from living animals.

Notes on cavern formation and deposition
Leaena’s Breath Cave (LBC). Cavern formation via large-scale collapse development ceased prior
to the widespread deposition of early-stage dark calcite (4.1–3.8 million years ago25) in LBC.
Subsequently, it has undergone only minor cavern enlargement through limited dome rifting and
boulder pile settling, as indicated by fracturing and alignment of speleothems. In the same period, LBC
has undergone some modification through collapse in approximately 25% of the total cavern area. This
includes a 620 m2 collapse that occurred prior to the deposition of the upper sediment layer, which was
deposited between 400 and 200 kyr ago. Limited collapse of ~140 m2 occurred after upper sediment
layer accumulated. Late-stage coralline calcite speleothems (~400 kyr, see main text) was deposited
over early-stage speleothems in an area concentrated but not confined to the northwest of the erosional
pit underlying the solution pipe entrance. Coralline calcite is deposited in relatively humid cave
environments when entrances are largely blocked, but sufficiently open to facilitate some air
interchange. A further 30% of the LBC cavern area, consisting of the more elevated section of cave, has
been covered in a fine powder up to 30 cm deep. This powder is formed as a result of roof exudation
and overlies areas with dark calcite, also to lesser extent areas of late-stage coralline calcite. Around
20% of the cavern area located in the lower lying section to the south of the entrance pit has been
covered with silty clay infill sediments. Present-day water flow within the cave is drained into the rock
pile within the confines of the entrance pit. The volume of water flow necessary to overflow the pit and
flood the 510 m2 expanse is prevented by the present entrance size and current surface topography.
The single solution pipe entrance to the cave penetrates 11 m of limestone along a near-vertical
joint. The upper 3 m of the pipe changes from a more irregular narrow form to a more rounded wider
form, reflecting greater limestone exudation. The current opening is a small ~0.36 m2 hole in a fragile
~4 cm thick layer of calcrete (kankar), which is formed at the base of the overlying clay soil horizon
during a period when the upper portion of the entrance pipe was last blocked. The soil layer remaining
above the calcrete cap is up to 1.2 m thick (Supp. Fig. 5). Dimensions of the pipe immediately below
the calcrete are 1.7 x 1.4 m. When open during the Pleistocene, the entrance had minimum dimensions
of 1.4 x 1.2 m (Supp. Fig. 6).

Pleistocene faunal remains were found on all surfaces in LBC, except for the base of the entrance
pit and area of last-stage collapse. They were found embedded in exudation sediments formed from
limestone breakdown, and atop coralline speleothems. The fossil-bearing, upper infill sediment layer
also overlies coralline speleothems. Three fossil specimens (WAM 04.6.02, WAM 04.6.3, WAM
03.5.9) were located under coralline calcite crusts.
Flight Star Cave (FSC) and Last Tree Cave (LTC). Large-scale collapse modification of FSC has
continued subsequent to the early Pliocene, as evidenced by voids in fallen roof blocks in-filled by dark
calcite of early Pliocene age25. The single solution pipe entrance of FSC is no longer a focus for
floodwater drainage, in contrast to the interval during which Pleistocene faunal remains and sediments
were accumulating in the cave. While the doline surrounding the FSC entrance retains some residual
soil, the doline surface is composed primarily of highly weathered calcrete and exposed limestone,
indicating that it has been open for a longer period than either LTC or LBC. Here the dolines show
limited clay erosion and the entrances occur in freshly fractured calcrete. LTC shows little evidence as
to the timing of the main collapse, apart from limited speleothem growth in the upper chamber along
with limited sections of collapse subsequent to Pleistocene faunal accumulation. Other blocked
entrances northeast of the present entrance are revealed by extensive floodwater scours in the accessible
lower levels within the corresponding section of this cave. Development in this area indicates a standing
water level that is tentatively suggested to have influenced the deposition of the Ossuary deposit (see
above).
