“…The extension rate of Campanile shells, and therefore the maximum temporal resolution that can be resolved in these archives, also exceeds other (nonmollusk) archives commonly used in paleoenvironmental reconstructions, such as coralline algae (up to 5 mm/year; Adey & Vassar, 1975) and the fastest growing coral species (e.g., Acropora valida ; up to 24 mm/year; Harriott, 1999; Nothdurft & Webb, 2007; and Acropora palmata , with maximum growth rates up to 90 mm/year; Bak et al, 2009). These growth rates are only matched by other giant gastropods, such as L. gigas (>400 mm/year along helix, Radermacher et al, 2009), Triplofusus giganteus (>100 mm/year along helix, Strauss et al, 2014), and C. symbolicum (>300 mm/year; this study; see Figure 7), demonstrating that these gastropod shells are among the fastest‐growing marine archives available for reconstructions. The warm, “tropical” climate conditions in the Lutetian Paris Basin (see section 4.5) may have contributed to Campanile gigantism, as such conditions are shown in modern seas and oceans to lower the relative cost of shell production in mollusks (Evans et al, 2018; Watson et al, 2017).…”

“…Fast‐growing mollusks like C. giganteum are especially valuable in this respect, since they potentially allow bridging the gap between reconstructions of climate and weather patterns by enabling sampling on the scale of hours to days (e.g., Warter et al, 2018). Other species that achieve similar high growth rates, such as giant gastropods like L. gigas (Berg, 1976) and Triplofusus giganteus (Strauss et al, 2014) and fast‐growing bivalves such as T. gigas (Warter et al, 2018) can be used to achieve similar results for a range of time periods as far back as the Cretaceous. Future studies should therefore focus on exploring the limits of these unique archives both in terms of temporal resolution and proxy interpretation.…”

Giant gastropods are among the largest mollusks in the fossil record, but their potential as paleoseasonality archives has received little attention. Here, we combine stable isotope and trace element analyses with microscopic observations and growth modeling on shells of two species of the gastropod genus Campanile: the extinct Campanile giganteum from Lutetian (~45 Ma) deposits in the Paris Basin (France), the longest gastropod known from the fossil record, and its modern relative Campanile symbolicum from southwestern Australia. The C. giganteum shells contain original aragonite and have pristine nacre in their apertures. We show that these gastropods attained growth rates exceeding 600 mm/year along their helix, depositing over 300 cm 3 aragonite per year. High growth rates and excellent preservation make C. giganteum excellent archives for reconstructing environmental change at high (potentially daily) temporal resolution, while providing enough material for methods such as clumped isotope analysis. Growth models show that Campanile gastropods grew nearly year-round, albeit slower in winter. Stable oxygen isotope ratios in modern C. symbolicum faithfully record a seasonal variability of 18-25°C in sea surface temperature, only failing to record the coolest winter temperatures (down to~16°C). Similarly, C. giganteum specimens likely record a nearly complete seasonal temperature range. Assuming constant sea water isotope composition, their oxygen isotope seasonality of up to 2.5‰ would translate to a Lutetian temperature range of 21-32°C in the Paris Basin. We hypothesize that these high and seasonally variable temperatures formed the breeding ground for the Lutetian shallow marine biodiversity hotspot in the Paris Basin.

Abstract. The aim of paleoclimate studies to resolve climate variability from noisy proxy records can in essence be reduced to a statistical problem. The challenge is to isolate meaningful information on climate events from these records by reducing measurement uncertainty through a combination of proxy data while retaining the temporal resolution needed to assess the timing and duration of the event. In this study, we explore the limits of this compromise by testing different methods for combining proxy data (smoothing, binning and sample size optimization) on a particularly challenging paleoclimate problem: resolving seasonal variability in stable isotope records. We test and evaluate the effects of changes in the seasonal temperature and hydrology cycle as well as changes in accretion rate of the archive and parameters such as sampling resolution and age model uncertainty on the reliability of seasonality reconstructions based on clumped and oxygen isotope analyses in 33 real and virtual datasets. Our results show that strategic combinations of clumped isotope analyses can significantly improve the accuracy of seasonality reconstructions if compared with conventional stable oxygen isotope analyses, especially in settings where the isotopic composition of the water is poorly constrained. Smoothing data using a moving average often leads to a dampening of the seasonal cycle, significantly reducing the accuracy of reconstructions. A statistical sample size optimization protocol yields more precise results than smoothing. However, the most accurate results are obtained through monthly binning of proxy data, especially in cases where growth rate or water composition cycles dampen the seasonal temperature cycle. Our analysis of a wide range of natural situations reveals that the effect of temperature seasonality on isotope records almost invariably exceeds that of changes in water composition. Thus, in most cases, isotope records allow reliable identification of growth seasonality as a basis for age modelling and seasonality reconstructions in absence of independent chronological markers in the record. These specific findings allow us to formulate general recommendations for sampling and combining data in paleoclimate research and have implications beyond the reconstruction of seasonality. We discuss the implications of our results for solving common problems in paleoclimatology and stratigraphy, including cyclostratigraphy, strontium isotope dating and event stratigraphy.
