Impressions of vertebrate bodies or their parts, such as trace fossils and natural molds of bones, are a valuable source of information about ancient faunas which may supplement the standard fossil record based on skeletal elements. Whereas trace fossils of animal activity are relatively common and actively studied within the field of ichnology, and natural impressions of internal or external surfaces are a frequent preservation mode in fossil invertebrates, natural molds of bones are comparatively rare and less extensively documented and discussed. Among them, internal molds (steinkerns) of turtle shells are a relatively well-known form of preservation, but the mechanisms and taphonomic prerequisites leading to their formation are poorly studied.

Nasal leech infestation is a rare etiology of epistaxis. Due to its insidious presentation and inconspicuous site of infestation, it is possible for the primary care setting to miss the diagnosis. We report a case of nasal leech infestation in an eight-year-old male child who was repeatedly treated for upper respiratory infection before finally being referred to the otorhinolaryngology clinic.

Leeches are an unusual cause of epistaxis and haemoptysis that should be considered in places with poor access to water. In this case report, we present a 7-year-old girl previously mismanaged as bacterial pharyngitis but later discovered to be a leech in the pharynx. She had ingested a leech from a spring that caused a foreign body sensation in the throat, frequent throat clearing, epistaxis, haemoptysis, and mild anaemia.
