 NOTE ADDED IN PROOF
 A fragment from a leaf-bearing rock from site 1 has revealed two 
fossil fruit specimens (Fig. 15.1-15.4). 
Also, a new cuticle morphotype was found from site 2, due to improved 
fluorescence equipment (Fig. 15.5-15.6). 
These specimens were discovered after manuscript acceptance. The fruits are 
preserved as compression-impressions with some three-dimensionality. These 
occurrences include the following three specimens. All scale bars in
Figure 15 equal 0.2 mm; all photographs 
were taken on the Nikon SMZ-1500 stereomicroscope.
 USNM 536213 (Fig. 
15.1, 15.2, part and counterpart). Icacinaceae cf. Palaeophytocrene (Reid, 
E.M., and Chandler, M.E.J. 1933. The London Clay Flora. British Museum 
[Natural History], London, England, 561 p.).  Oval, tuberculate endocarp. 
Tubercules extend towards center of fruit, tubercles in vertical rows. 
Dimensions preserved: 2.7 mm length, 1.2 mm width.  USNM 536214 (Fig. 
15.3, 15.4, part and counterpart). Juglandaceae sp., endocarp. The single 
specimen is ovoid and basally lobed internally. The endocarp is apparently 
without a wing and two-lobed, but more specimens would be needed to determine 
these characters and better assign this fruit taxonomically. Dimensions 
preserved: 1.3 mm length, 0.8 mm width. USNM 536215 (Fig. 
15.6; Fig. 15.5 shows a separated fragment of the same morphotype, on the 
same rock). Dicot cuticle morphotype with densely spaced, diffuse paracytic 
stomata and trichome bases, visible under fluorescence microscopy with long-pass 
green filter. Spherical resin bodies are also visible in the carbon film between 
cuticle layers (Fig. 15.5), and these 
are probably organically preserved oil/mucilage idioblasts common in tissues of 
Laurales, Magnoliales and basal ‘ANITA’ grade angiosperms. These resin bodies 
are also visible, under fluorescence, in the Lauraceae leaf morphotype exemplar 
(Fig. 2.3), further confirming that 
specimen as Lauraceae. |
