Ramphosus rastrum (Volta, 1796) Eocene Monte Bolca near Verona Italy Length 5cm -
A few weeks ago I was looking for a new case for my iPhone. So I browsed around a Chinese internet shop. I came across cases with fossil pictures on the back: Icaronycteris from the Green River Formation, a Seymouria from the Permian, Aipichthys velifer from the Cretaceous of Lebanon, Archaeopteryx from Solnhofen, a fossil turtle (Green River?) and finally a Sparnodus vulgaris from the Eocene of Monte Bolca, Italy. Funny only that this Sparnodus vulgaris seemed so familiar to me! No wonder - the original is in my collection and hangs on the wall in the corridor. The Chinese company searched for some templates in the internet and found them at TFF. They probably downloaded the picture here in the forum. Now I have an IPhone housing with the image of a fish from my own collection. Thomas

Taxonomy from Bannikov & Carnevale, 2017. Bannikov & Carnevale 2017, p. 319:" Its type species, †P. lessinii Blot, 1980, was described based on a single partially complete specimen in the collections of the Museo Civico di Storia Naturale, Verona (Blot, 1980, p. 365; pl. VI, fig. 3). Subsequently, an additional incomplete specimen housed in the Carnegie Museum of Natural History, Pittsburgh, was referred to †P. lessinii and figured by Frickhinger, 1991, p. 769); however, this specimen lacks the characteristic cranial horn emerging just above the orbit considered diagnostic by Blot (1980)." Photo of the holotype of Prosolenostomus lessinii in Bannikoy & Carnevale 2017, p. 320: This here is the third known specimen of Prosolenostomus. Like the specimen from the Carnegie Museum of Natural History, Pittsburgh, illustrated by Frickhinger 1991, p. 769, this Prosolenostomus has no cranial horn, and is therefore a new, as yet undescribed species. A. Bannikov wrote (personal communication, 13.12.2021) " the "cranial horn" is not a conservation artifact, but a genuine diagnostic feature. Therefore your specimen belongs to the till undescribed taxon. Overall, pipefishes are very rare in Monte Bolca." Diagnosis for the genus Prosolenostomus from Blot, 1980, p. 365 (translated from French by oilshale); "Very elongated body. Cuirass constituted by cruciform scutes, imbricated the ones in the others, delimiting more or less abundantly reticulated beaches. Very large branchial opening. Short head with very high rostral tube and terminal mouth; very strong mandibles. A rather high horn rises above the orbit. " Identified as cf. Prosolenostomus sp. by A. Bannikov (Borisyak Paleontological Institute, Russian Academy of Sciences).

Prosolenostomus lessinii Blot 1981 Eocene Monte Bolca near Verona Italy The species of the family Syngnathidae belong to the order Syngnathiformes. The name "Syngnathiformes" means "conjoined-jaws". Syngnathiformes is an order of ray-finned fishes that includes among others false pipefishes, ghost pipefishes and tubemouth fishes (Solenostomidae), pipefishes and seahorses (Syngnathidae), razorfishes (Centriscidae), trumpetfishes (Aulostomidae) and cornetfishes (Fistulariidae). Fishes of this order have elongate, narrow, bodies surrounded by a series of bony rings, and small, tubular mouths. The tubular mouth shows that these members of the Syngnathiformes fed on small Crustaceans and such, much as their modern-day relatives Seahorses and Pipefishes. The family Syngnathidae includes the pipefishes and seahorses as well as the leafy and weedy sea dragons. The species of the subfamily Solenostomidae (false pipefishes) have elongated, thin, snake-like bodies with a highly modified skeleton formed into armored plating. The head is elongate with a long and slender, tubular snout; the mouth being small and toothless. The dorsal fin is the main part of locomotion. They are very weak swimmers in open water, moving slowly by means of rapid movements of the dorsal fin. In many respects, they are similar to the pipefishes (Syngnathidae), but can be distinguished by the presence of pelvic fins, a prominent, spiny, dorsal fin and star-shaped plates on the skin. The species of the subfamily Solenostomidae are abundant on coasts of the tropical and temperate zones. Most species of pipefish are usually no longer than 15 cm in length and generally inhabit sheltered areas in coral reefs, seagrass beds and sandy lagoons. -
