Description
Original diagnosis after Ivanov, 2020 [28808]: Tricuspid teeth with pyramidal crown labio-lingually flattened; overhangs labially behind the base, with a triangular large central and two small lateral cusps fused at the base and separated upward by triangular notches; cusps thickened in the upper part; lateral carinae well-developed along the entire crown; distinct ornamentation from inverted “V”-nested and longitudinal ridges with incurved cristae on both of the cusp sides; a narrow groove marks the crown/base junction; considerably vascularized, lingually extended base, with rows of numerous foramina on the occlusal and basal sides; vascular network formed of transverse horizontal, ascending and large longitudinal canals.
