content: Fragment of fossilized impressions of a dicot leaf left in rock. It measures around 19 cm x 14 cm x 5 cm in size or less. These fossils show evidence of hole feeding and margin feeding insect damage. Hole feeding is caused when an insect with chewing mouthparts eats through a portion of a leaf. Margin feeding is when an insect with chewing mouthparts eats from the edge in towards the center of the leaf. The specific type of hole feeding is identified as damage type (DT) 01: small-sized circular perforations, less than 1 mm in maximum diameter. Two specific types of margin feeding are identified as damage types DT12: circular, shallow to deep excision of leaf margin, < 180 degrees of arc and DT15: a deeply incised or otherwise trenched excision of the leaf blade that expands inwardly from the leaf margin.
