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).

Lates is a genus of freshwater and marine fish belonging to the order Perciformes. The lates species are now native to the Indian and western Pacific Oceans and to rivers and lakes in Africa. The lates species are generally carnivorous, feeding on invertebrates and other fish. The Nile perch, Lates niloticus, is one of the largest freshwater fish, it reaches a maximum length of nearly two metres (more than six feet), weighing up to 200 kg (440 lb).

Recent Sphyraenea barracuda, own work of Laban712 (from Wikipedia): The genus Sphyraena (from Latin: "pike-like") belongs to the order Perciformes. Members of the genus Sphyraena, better known as Barracudas, are elongated fish, pike-like in appearance, with large pointed heads and jaws. The two dorsal fins are widely separated with the anterior fin having five spines, the posterior fin having only one spine and nine soft rays. The posterior dorsal fin is similar in size to the anal fin and is situated above it. Barracudas normally have an under bite with prominent sharp-edged fang-like teeth in sockets. The oldest known barracuda fossil found so far dates to the Eocene period. All members of the genus Sphyraena are voracious predators; they feed upon cephalopods and crustaceans but mainly prey on fishes. Young barracudas can be often seen in small schools. Adult barracudas are considered to be solitary when it comes to hunting. The great barracuda can swim up to 35 mph, yet it can move forward slowly with no apparent effort; thus increasing its stealth. Barracuda are found primarily in tropical and subtropical waters of the Atlantic, Indian, and Pacific oceans, but certain species such as the Great Barracuda lives in brackish water.

Taxonomy from Fossilworks.org. The order Beryciformes, a poorly understood group, is represented in Monte Bolca with at least two species: Eoholocentrum and Berybolcensis, both from the subfamily Holocentrinae or squirrelfish (L. Sorbini, 1984). Both species seemed to be largely or entirely nocturnal and lived in deep marine waters; their eyes are amazingly large. References: Sorbini, L., 1979.

Diodon holocanthus, inflated (own work of Ibrahim lujaz from Rep. Of Maldives) Diodon nicthemerus (own work of user Springcold at da.wikipedia) Porcupinefish belong to the family Diodontidae within the Tetraodontiformes order and are also commonly called blowfish. They have the ability to swallow water or air and to inflate their body making it harder for predators to swallow them. When the fish inflates, sharp spines radiate outwards as a second defense mechanism. Some species are poisonous, having tetrodotoxin in their internal organs. Fugu is the Japanese word for pufferfish and is also a Japanese dish made out of the pufferfish meat. Because fugu is lethally poisonous if prepared incorrectly, fugu has become one of the most celebrated and notorious dishes in Japanese cuisine. Porcupinefish are medium to large sized fish and are found in shallow temperate and tropical seas worldwide. Monte Bolca is an important lagerstatte for Tetraodontiformes with Diodon tenuispinus as one of its oldest records. References: J. C. Tyler and F. Santini (2002) Review and reconstructions of the tetraodontiform fishes from the Eocene of Monte Bolca, Italy, with comments on related Tertiary taxa.
