#WormWednesday traditionally referred to as 'Filograna avita', this calcareous worm commonly encrusted shells of inoceramid #bivalve molluscs on the chalk seafloor during the early Turonian (~94 million years ago). This association is found throughout southern 🇬🇧 and northern 🇫🇷 at the same horizon.
